In recent years, with the improvement of shipbuilding technology and the development of offshore fishing, marine chillers have attracted more and more attention. Marine chillers are high-end models designed for marine environments. The use of environmentally friendly refrigerants, improved energy-saving effects, optimized structures, reduced consumables, reduced volume, reduced weight, reduced noise, and improved comfort are all important features that reflect the development of marine chillers to meet the needs of ship modernization.   Marine chillers usually use a vapor compression refrigeration cycle, and their working principle is similar to that of land-based chillers. It compresses the low-temperature and low-pressure refrigerant gas into a high-temperature and high-pressure gas through a compressor, and then sends it to the condenser, dissipates heat through the cooling medium (usually seawater), and condenses the refrigerant gas into liquid. The liquid refrigerant enters the evaporator after being reduced in pressure by the throttling device, and absorbs the heat of the cooled medium (such as air, water, etc.) in the evaporator, thereby achieving the purpose of refrigeration. The cooled medium is then transported to the equipment or system that needs to be cooled through a pipeline to complete the entire cooling cycle.   The main components of marine chillers are compressors, condensers, evaporators, throttling devices and control systems. The compressor is the core component of marine chillers. Common types include piston, reciprocating compressors, screw compressors (semi-closed or open) or scroll compressors. The condenser usually adopts a shell and tube structure, the interior is generally nickel-copper, and the cooling medium is seawater. In order to prevent seawater from corroding the condenser, the condenser is usually made of corrosion-resistant materials, such as titanium alloy, stainless steel, etc. The evaporator usually adopts a shell and tube or plate structure, which can be replaced with stainless steel according to customer needs. The design of the evaporator needs to take into account the space limitations and cooling requirements of the ship, and usually needs to have the characteristics of efficient heat exchange, small size and light weight. The function of the throttling device is to reduce the pressure of the liquid refrigerant discharged from the condenser, making it a low-temperature and low-pressure refrigerant liquid, and enter the evaporator for evaporative cooling. Common throttling devices include capillary tubes, thermal expansion valves and electronic expansion valves. The control system monitors and controls the operating status of the chiller to ensure the safe and stable operation of the chiller. The control system usually includes temperature sensors, pressure sensors, controllers, displays and other components. Marine control systems usually need to have high reliability and strong anti-interference capabilities to adapt to the complex electromagnetic environment of ships.   Hengde Marine Chiller: When customers purchase marine chillers, the cooling capacity is basically 12HP+; The main engine uses compressors such as Bitzer, Copeland, and Hanbell, which are of stable quality and reliable operation;  The shell and tube heat exchanger designed for seawater is adopted, and corrosion-resistant materials such as nickel white copper, aluminum brass, titanium alloy, and stainless steel are used, with high heat exchange efficiency and long service life. Control system: Industrial-grade centralized control system, Chinese and English operation interface, you can check the unit operation status at any time, adjust the working mode, accurately control the matching of the unit's cooling capacity and cold load, ensure the unit operates at normal efficiency, and reduce operating costs. It integrates multiple protection functions such as water flow, low temperature, high and low pressure, antifreeze, reverse phase loss, delayed start, overload, overtemperature, and oil pressure difference. Accurate control can control the temperature within the range of ±1℃, easy to operate, stable and reliable, etc.   Solution: Five years ago, a marine shipyard in Maldives found us. According to the feedback from its customers, the current ships have no refrigeration equipment. Many fish died after being caught on board due to the large temperature difference. Therefore, they wanted to equip all ships with chillers. Since equipped with our chillers, the water temperature has been maintained to keep the fish fresh. The customer was impressed by the performance and function of our chillers. Now they are building a new factory to build ships and prepare to equip all subsequent ships with Hengde's marine chillers.

Mold temperature controllers for the plastics industry: Mold temperature controller is mainly used to control the temperature of plastic molds to ensure that plastic products can be quickly cooled and maintain the desired shape during the injection process.    In plastic injection molding, blow molding, extrusion and other processes, the appropriate mold temperature can ensure that the plastic melt flows, fills and solidifies well in the mold. For example, for some engineering plastics that require a higher mold temperature to achieve a good molding effect, the mold temperature controller can accurately control the mold temperature within the required range, improve the surface quality, dimensional accuracy and mechanical properties of the product, reduce surface marks and internal stress, prevent the product from shrinking and deforming, facilitate demolding, and accelerate product shaping to improve production efficiency. The mold temperature controller can also be used for circulating water supply of the cooling system of the injection molding machine to improve the efficiency and stability of the injection molding machine.   Chillers for the plastics industry： Chillers are mainly used to cool plastic products and molds. During the plastic processing process, a large amount of heat will be generated. If it is not cooled in time, it will affect the quality and production efficiency of the product. The industrial chiller quickly reduces the temperature of the mold and plastic products by circulating cooling water to prevent the product from deforming due to overheating and generating internal stress. In addition, industrial chillers can also play an important role in some plastic processing processes that require a low temperature environment. For example, injection molding, extrusion molding. Mold temperature controllers and chillers for the rubber industry: In the rubber processing industry, mold temperature controllers are widely used in industries such as rubber film calendering and hot press vulcanization. They can control the vulcanization process of rubber materials by heating and cooling the molds, thereby obtaining the required hardness and elasticity, and accurately controlling the temperature of the rubber mold. In the vulcanization process of rubber products, the appropriate temperature can ensure that the rubber is fully vulcanized and improve the physical properties and quality stability of rubber products. For example, for some special rubber products, the mold temperature controller can stabilize the mold temperature within a specific range according to the process requirements, thereby ensuring the dimensional accuracy and appearance quality of the product. At the same time, the mold temperature controller helps to improve production efficiency and shorten the vulcanization time.   Chillers are mainly used to cool rubber products, such as the production of automobile tires and rubber seals. They can also be used to cool production equipment, such as rubber mixers, calenders, etc. In the rubber processing process, the operation of the equipment will generate a lot of heat. If it is not cooled in time, it may affect the normal operation and service life of the equipment. The chiller can quickly reduce the temperature of the equipment by circulating cold water to ensure stable operation of the equipment. For rubber products, the chiller can quickly cool the products after vulcanization to prevent deformation and improve the dimensional stability and quality of the products.   Project Cases：

The food, beverage and packaging industries require precise temperature control to meet the requirements of their manufacturing processes. Hengde mold temperature controllers can accurately control the temperature during food processing to ensure that all types of food are processed within the most appropriate temperature range. Whether it is grains, oils, chocolates, biscuits or other different foods, the temperature must be strictly controlled during the processing. Only in this way can the excellent quality of the product be guaranteed; in beverage production, some raw materials need to be processed at a specific temperature. For example, when producing tea beverages, the mold temperature controller can heat water to a suitable temperature for tea extraction, improve the extraction efficiency and the quality of the tea soup.     Hengde chillers are mainly used for cooling canned products and beer. During the beverage filling process, the filling equipment will generate heat, and the chiller can provide it with cooling water in time to ensure the quality and taste of the beverage. For example, on the filling line of bottled beverages, the chiller can provide cooling water for the filling head and conveyor belt to prevent the beverage from generating bubbles or deteriorating due to excessive temperature during the filling process. In the process of food fermentation, temperature is a key control factor. The chiller can control the speed and temperature of fermentation by cooling the temperature of the fermentation tank or fermentation chamber to ensure the stability and consistency of the fermentation process. For example, in yogurt production, the water chiller can control the temperature of the fermentation tank at around 40℃, providing a suitable temperature environment for the growth of lactic acid bacteria and ensuring the fermentation quality of yogurt.     At the same time, Hengde mold temperature controllers and Industrial chillers are also used in the packaging supporting industries of food and beverages. For example, when producing food plastic bottles such as PET, PE and PP, the mold temperature controller can keep the plastic raw materials at a stable temperature during the extrusion, blow molding and other process links, thereby ensuring the quality and production efficiency of the film and meeting different packaging needs; in the process of printing packaging materials, the appropriate temperature can make the fluidity and drying speed of the ink reach the best state, and the mold temperature controller can control the temperature of the printing plate, ink, etc. of the printing press, improve the clarity and color saturation of the printing, and ensure the quality of the printed pattern. In addition, for some special printing processes such as hot stamping and laminating, the mold temperature controller can also provide a stable temperature environment to ensure the smooth progress of the process; the mold temperature controller can also provide accurate temperature for the heat sealing equipment, so that the packaging material can be quickly and evenly heated during the heat sealing process, thereby forming a firm seal.    In the food packaging industry, water chillers are mainly used for equipment cooling, packaging material cooling and product cooling. Many equipment in the packaging industry will generate a lot of heat during operation, such as aluminum-plastic blister packaging machines, heat sealing machines, etc. Water chillers can provide cooling circulating water for these equipment, take away the heat generated by the equipment in time, and keep the temperature of the equipment within the normal range. Thereby improving the stability and reliability of the equipment and extending the service life of the equipment; in the molding process of plastic packaging materials, the plastics after high-temperature processing need to be cooled quickly in order to shape them. Water chillers can provide low-temperature cooling water to accelerate the cooling speed of plastic packaging materials and improve production efficiency. At the same time, the size of the cooled packaging materials is more stable and not easy to deform, which is conducive to subsequent packaging operations; for some products that need to be cooled before packaging, such as food after high-temperature cooking, water chillers can quickly cool them to a suitable packaging temperature. This can avoid deformation, deterioration and other problems caused by excessive temperature during the packaging process, and ensure the quality and safety of the product.

With the continuous advancement of science and technology, mold temperature controllers and water chillers are increasingly used in the chemical industry. Hengde mold temperature controllers and water chillers are mainly used for temperature control and cooling of reactors.     As the core equipment for various chemical reactions, many chemical reactions will release a lot of heat. If they are not cooled in time, the reaction temperature may be too high, causing danger or even causing the reaction to get out of control. Hengde water chillers can provide low-temperature cooling water for the reactor, quickly take away the heat generated by the reaction, and ensure that the reaction is carried out within a safe temperature range. For example, in some highly exothermic reactions, the water chiller can accurately control the temperature of the reactor through a circulating cooling system to ensure the smooth progress of the reaction. At the same time, the water chiller can also adjust the cooling water volume and water temperature according to the progress and needs of the reaction to achieve precise control of the reaction temperature. In addition, the agitator, seals and other equipment components in the reactor are easily damaged in a high temperature environment. The cooling effect of the water chiller can reduce the equipment temperature, extend the service life of the equipment, and reduce the cost of maintenance and replacement.   Hengde mold temperature controller can accurately control the temperature in the reactor to ensure that the reaction is carried out under the optimal temperature conditions. With stable heating or cooling functions, the reaction temperature is always maintained within the set range to avoid the reaction rate, selectivity and yield affected by temperature fluctuations. For example, in some polymerization reactions, the mold temperature controller can accurately control the temperature, promote the formation of polymers, and improve product quality. For some reactions that need to be started at a specific temperature, the mold temperature controller can quickly and evenly heat the reactor so that the reaction system quickly reaches the required temperature and speeds up the start-up of the reaction. For example, in some catalytic reactions, the catalyst needs to be activated at a certain temperature, and the mold temperature controller can provide an accurate heating process to ensure that the catalyst performs at its best.   Of course, Hengde mold temperature controllers and chillers can also be used in other areas of the chemical industry, such as preheating and insulation of materials, cooling and storage of materials, and are also widely used in fine chemical production fields such as pharmaceuticals and cosmetics. In the production process of chemical equipment, compressors, vacuum pumps, agitators, etc. can be cooled; in the process of chemical cleaning, coating and other links, it can also play a cooling role.   The chemical industry usually operates in a high temperature environment, and the requirements for mold temperature controllers and chillers are extremely strict. First, they must operate stably in high-temperature environments, which requires their components to be resistant to high temperatures and the cooling system to be able to effectively dissipate heat at high temperatures. Second, chemical-specific mold temperature controllers and water chillers must operate stably in high-pressure environments and achieve precise temperature control to achieve temperature control effects. Third, given the characteristics of the chemical industry, many buyers tend to choose explosion-proof mold temperature controllers and explosion-proof chillers when purchasing mold temperature controllers and chillers.

In some special processes in the electronics industry, such as the assembly of LCD screens and the packaging of electronic chips, hot pressing operations are required. The mold temperature controller can provide stable high temperature and pressure to ensure the smooth progress of the hot pressing process and improve the reliability and performance of the product; in the processes of shell molding and circuit board manufacturing of electronic products, the mold temperature controller helps to improve product quality and production efficiency by maintaining the stability of the mold temperature. Especially in plastic processing processes such as injection molding, blow molding, and extrusion molding, the application of mold temperature controllers is particularly critical because it can control the temperature of the mold to obtain high-quality finished products.   The application of Hengde chillers in the electronics industry is mainly reflected in the cooling of equipment and process cooling. Many equipment used in the electronic manufacturing process, such as lithography machines, etching machines, deposition equipment, etc., also need cooling to maintain a stable operating temperature. The chiller can provide low-temperature cooling water for these equipment to ensure that the accuracy and performance of the equipment are not affected by temperature. For example, the optical system of the lithography machine is very sensitive to temperature, and even a slight temperature change may affect the exposure accuracy. The chiller can ensure that the optical system of the lithography machine works at a constant temperature by accurately controlling the cooling water temperature, thereby improving production efficiency and product quality.   In the laser cutting, welding, marking and other processes in the electronics industry, the laser generator generates a lot of heat. The chiller can provide cooling for the laser generator to prevent overheating damage while ensuring the stability and accuracy of the laser output. For example, when laser cutting electronic circuit boards, water chillers can cool the laser head to prevent overheating and reduce cutting accuracy; during the testing of electronic components, the components need to be cooled to a specific temperature for performance testing. Water chillers can provide precise low-temperature cooling to meet the requirements of electronic component testing.  

Hengde's state-of-the-art mold temperature controllers and industrial chillers provide the precise temperature control, reliability and durability required by the automotive industry.   Application of mold temperature controllers in the automotive industry: Hengde mold temperature controllers can accurately control the mold temperature during the injection molding process of auto parts to ensure that the plastic melt flows and fills evenly in the mold. For example, for the injection molding of automotive interior parts, mold temperature controllers can make the plastic surface smoother and reduce defects such as shrinkage marks and warping.   Mold temperature controllers are also used in the vulcanization process of automobile tire manufacturing. The appropriate vulcanization temperature can fully cross-link the rubber material of the tire, improve the strength, wear resistance and durability of the tire, and reduce the defective rate.   In the automotive painting process, the mold temperature controller can provide a stable heat source for the drying furnace and accurately control the drying temperature. The appropriate drying temperature can make the paint dry and solidify quickly, form a solid coating, improve the quality and durability of the coating, reduce production costs, and make it meet the energy-saving and environmental protection requirements of the automotive industry.   Application of chillers in the automotive industry: During the automobile manufacturing process, Hengde chillers can cool various equipment. Such as stamping equipment, various welding equipment and coating equipment. Ensure that the equipment operates within the normal temperature range to prevent overheating from affecting the accuracy and service life of the equipment. For example, the punch and die of the high-speed stamping machine will heat up rapidly during operation. The chiller will take away the heat in time through the circulating cooling system to ensure the stability of the stamping process; the laser head of the laser welding equipment needs to work within a specific temperature range. The chiller can accurately control the cooling water temperature to ensure the stability of the laser output and the welding accuracy; the fan and heating elements of the drying furnace will generate a lot of heat after long-term operation. The chiller can cool the fan motor and extend its service life.   With the development of the times, the new energy vehicle industry is booming. Hengde Company also keeps up with the trend of the times and has done a lot of cases about the new energy vehicle industry. In the lithium battery industry, the roller press is a very important processing equipment. Hengde mold temperature controller can be used for roller pressing to control the thickness of the grade. Hengde chiller can be used to cool the slurry trolley.

In the die casting process, precise control of the mold temperature is essential. The mold temperature controller can ensure that the mold works within the appropriate temperature range, so that die casting materials such as aluminum alloys and magnesium alloys are fully filled, uniformly solidified and cooled in the mold. For example, for die casting parts with complex structures, the appropriate mold temperature can allow the molten metal to flow smoothly in the mold, avoiding local overheating or overcooling, so as to obtain high-quality castings. Different die casting materials have different requirements for mold temperature. The mold temperature controller can flexibly adjust the mold temperature according to different materials and casting requirements to meet various die casting process requirements. For example, the mold temperature is usually between 180℃ - 250℃ during aluminum alloy die casting, while magnesium alloy die casting requires a higher mold temperature, generally between 250℃ - 350℃.   During the die casting process, the mold will heat up rapidly, and excessive temperature affects the casting quality and mold life. The chiller provides low-temperature cooling water to quickly reduce the mold temperature and restore the mold to a suitable working temperature in a short time. For example, after completing a die-casting cycle, the chiller quickly reduces the mold temperature from high temperature to the set cooling temperature to prepare for the next die-casting. For high-precision die-casting parts, the chiller can control the mold temperature within ±1℃ to ensure stable casting quality. The die-casting workshop is usually hot, especially in summer, and the high temperature environment affects the work efficiency and health of workers. The chiller cools the mold and equipment to reduce the workshop temperature and improve the working environment. In large die-casting workshops, the operation of the chiller can reduce the workshop temperature by 5℃ - 10℃, improving the working comfort of workers.     Hengde's mold temperature controllers and industrial chillers are designed to meet the extreme thermal dynamics of die-casting applications and have proven to be a reliable, efficient and durable choice.  

The application of Hengde mold temperature controller and chiller in the construction industry is mainly used for temperature control of aluminum-plastic panel production lines and concrete mixing plants.   Aluminum-plastic panels can be used for building exterior walls or home decoration. In the production process of aluminum-plastic panels, aluminum panels and plastic core materials need to be compounded. The mold temperature controller can accurately control the heating temperature in a short time to ensure that the aluminum panel and plastic core material are evenly heated during the compounding process. This helps to improve the bonding strength and flatness of the aluminum-plastic panel and reduce surface defects such as bubbles and delamination. For example, after heating the aluminum panel and the plastic core material to a specific temperature, they are tightly combined through a hot pressing process. The uniform heating of the mold temperature controller can ensure the consistent quality of the entire panel. At the same time, by accurately controlling the temperature, the mold temperature controller can avoid overheating or unnecessary heating, thereby reducing energy consumption.   The mold temperature controller can also provide a stable temperature to accelerate the hydration reaction of concrete, thereby shortening the curing time. For example, during winter construction, the mold temperature controller can control the curing temperature within a suitable range to prevent the concrete from being damaged by freezing due to low temperature. In a concrete mixing plant, raw materials such as cement, aggregates and water will generate a lot of heat during the mixing process. If not cooled in time, the temperature of the concrete will be too high, affecting the quality and construction performance of the concrete. The chiller can provide cooling water for the concrete mixing plant to reduce the temperature of the concrete. For example, in hot summer weather, the chiller can control the temperature of the concrete below 30℃ to ensure that the slump and fluidity of the concrete meet the construction requirements. At the same time, the chiller can also adjust the cooling water volume and water temperature according to the concrete mix ratio and mixing time to achieve the best cooling effect.

The textile industry is an important manufacturing field. In production, many equipments need rapid heating and cooling. Mold temperature controllers are widely used for heating textile drying ovens. They offer better stability and precise temperature control than steam heating systems. The mold temperature controller heats circulating medium and exchanges heat with the oven for heating and constant temperature control. It can also control the temperature of textile equipment molds and heat setting equipment.   Industrial chillers are used for cooling textile equipment like coating machines and printing machines. They can cool equipment generating heat and provide cooling for fabrics. Chillers can also be a cold source for air-conditioning systems in workshops.  

Now the mold temperature unit, or MTC, is generally controlled by a water temperature controller and an oil temperature controller. In the oil and gas industry, oil mold temperature controllers are generally used more. It is mainly used for crude oil extraction, natural gas processing, pipeline transportation, oil storage and transportation, and chemical reactions such as reactor temperature control.     In cold areas or in winter, the viscosity of crude oil will increase due to low temperature, and the fluidity will deteriorate. The mold temperature controller can heat the wellhead equipment and pipelines to maintain the appropriate temperature of crude oil, ensure that it is smoothly extracted from the ground and flows in the pipeline, and improve the extraction efficiency; the wax contained in crude oil is easy to precipitate and adhere to the inner wall of the oil pipe at low temperature, affecting the normal production of the oil well. By controlling the temperature within a certain range through the mold temperature controller, the precipitation of wax can be prevented, the frequency of wax cleaning operations in the oil well can be reduced, and the maintenance cost can be reduced. Many chemical reactions in the refining process, such as cracking, reforming, hydrogenation, etc., need to be carried out at a specific temperature. The mold temperature controller can provide accurate and stable temperature control for the reactor, so that the reaction can be carried out efficiently and safely, and the quality and yield of the product can be improved. High-viscosity oil products need to flow smoothly at higher temperatures. Mold temperature controllers can be used to heat oil storage tanks and delivery pipelines to ensure the normal storage and delivery of oil products.   Since oil and natural gas are flammable and explosive substances, when purchasing a mold temperature controller, you must choose a mold temperature controller that meets explosion-proof standards and regularly check the explosion-proof components of the equipment, such as explosion-proof motors and explosion-proof controllers, to ensure their normal operation. The explosion-proof mold temperature controller is a new type of temperature control equipment product designed based on the standard mold temperature controller. It adopts an excellent explosion-proof structure, complies with relevant safety certification standards, and is provided with an explosion-proof grade certificate by the manufacturer. It is particularly suitable for the petrochemical industry.   Solutions: When a contractor in oil and gas contacted Hengde company, we accepted the challenge. They need two-75kw oil heaters with PCEC standard. Our oil heater has two explosion-proof type, CT gas explosion-proof and BT dust explosion-proof, they need CT-Gas Explosion Standard. As they working in the oil field, the electrical systems must be explosion proof. Finally, we successfully made a 75kw oil temperature controller that met the customer's requirements. The customer was very satisfied and ordered several other models of mold temperature controllers in the later cooperation.    

In daily life and production, many surface treatment processes use chillers, such as electroplating, micro-arc oxidation, electrophoretic coating, anodizing, vacuum coating, etc.   Chillers for electroplating (electroplating chillers, electroplating water chillers, electroplating refrigeration units, electroplating chillers) are widely used in zinc plating, nickel plating, chromium plating, copper plating, tin plating, aluminum oxidation and other enterprises. Their micro-arc oxidation production lines, electroplating production lines, electrophoretic production lines, and anodizing production lines will use this process. It includes many physical and chemical methods such as pre-treatment, electroplating, coating, chemical oxidation, thermal spraying, etc., using acidic or alkaline solutions to react chemically with oxides and oil stains on the surface of the workpiece, so that they are dissolved in acidic or alkaline solutions to remove rust, oxide scale and oil stains on the surface of the workpiece. In these process processing, temperature has an important influence on the surface quality and efficiency of electroplating, because when the solution temperature is too high, it will overheat and cause waste of energy and evaporation of the plating solution. And it will also cause damage to the processed products themselves. The electroplating special chiller solution is designed to solve this problem. In the electrogalvanizing process, the appropriate temperature range is 20℃-40℃, and the chiller water temperature is usually set to about 10℃ to cool the zinc plating solution.   Vacuum coating chillers are suitable for various surface treatment fields such as vacuum coating. They are ideal supporting equipment for scientific instruments such as ultra-high vacuum sputtering instruments, X-ray machines, vacuum furnaces, coating machines, accelerators, etc. The medium-frequency magnetron sputtering target in the vacuum coating equipment has a high frequency and a large current. When it is fired, it will generate high temperature and deform the gun. Therefore, a medium-hole tube is used as a conductor and water is added in the middle to cool the gun. Hengde vacuum coating chiller can provide cooling water with constant temperature, constant pressure and constant flow, and can accurately control the temperature of the vacuum coating machine to ensure the high quality and high efficiency of the plated parts.   Anodizing process: This process requires strong electrical bonding at high temperature to complete the surface treatment, which will generate a lot of heat. The chiller uses a heat exchanger or a coil containing liquid to reduce the temperature level, maintain normal temperature, protect the industrial environment from high temperature, ensure the smooth progress of the process and the quality of the product. For example, when aluminum oxidation is carried out, the temperature of the solution in the oxidation tank will rise. When it is higher than a certain temperature, the quality of aluminum oxidation will be affected and the expected effect cannot be achieved. Therefore, it is necessary to use an aluminum oxidation chiller to cool the solution in the tank. The aluminum oxidation industry is very corrosive and special anti-corrosion treatment must be used. According to the temperature, it can be divided into high-temperature oxidation (ordinary oxidation) and low-temperature oxidation (hard aluminum oxidation). High-temperature oxidation generally controls the temperature at around 20°C, and an ordinary chiller can be used; while the low-temperature oxidation temperature is between -4 and 4°C, and a low-temperature chiller must be selected (ethylene glycol must be added to the water).   Micro-arc oxidation process: During the micro-arc oxidation process, a large amount of heat will be generated, and the reaction system needs to be cooled. The chiller can provide a stable low-temperature environment for the process, ensure the normal progress of the reaction, and improve the quality and performance of the oxide film.   Electrophoretic coating process: In this process, the paint needs to be electrophoretically deposited at a certain temperature. If the temperature is too high, it will affect the performance and coating effect of the paint. The chiller can cool the electrophoretic paint, keep the temperature of the paint within a suitable range, and improve the quality and efficiency of the coating.
