In the electroplating industry, maintaining a stable and appropriate temperature is crucial for the quality of the plating process. This is where the choice between water cooled chillers and air cooled chillers becomes a significant decision. Let's explore the pros and cons of each to help you make an informed choice for your electroplating operations.​   Cooling Efficiency​ Electroplating water cooled chillers generally offer higher cooling efficiency. Water has a much higher heat - transfer coefficient compared to air. In an electroplating plant, where large amounts of heat need to be dissipated quickly, a electroplating water chiller can transfer heat more effectively. For example, in a large - scale electroplating production line with high volume plating tanks, a electroplating water cooled chiller can rapidly cool the plating solution, ensuring a consistent temperature. This is essential for achieving uniform plating thickness and high quality finishes.​   On the other hand, electroplating air chillers rely on air to dissipate heat. While they are suitable for some applications, their cooling efficiency is relatively lower. The heat transfer in air cooled systems is slower, which may not be sufficient for high heat load electroplating processes. However, for smaller electroplating shops with lower heat generation, an electroplating air cooled chiller might be adequate.​   Installation and Space Requirements​ Air cooled chillers are more straightforward to install. They do not require a complex water cooling tower or a dedicated water supply system. This makes them an attractive option for facilities where space is limited or where the installation of a water cooling infrastructure is not feasible. For instance, in a compact electroplating workshop located in an urban area with restricted space, an electroplating air cooled chiller can be easily placed on the floor, saving valuable floor space.​   Water cooled chillers, in contrast, need a cooling tower and a network of pipes for water circulation. The installation of these components requires more space and careful planning. The cooling tower needs to be placed in an area with good air circulation, which may not always be available in some electroplating facilities. Additionally, the plumbing work for the water cooled system can be more complex and time consuming.​   Energy Consumption​ Electroplating coating water cooled chillers tend to consume less energy in the long run, especially in large scale operations. Their higher cooling efficiency means that they can achieve the same cooling effect with less power input compared to electroplating coating air cooled chillers. In an electroplating factory that operates around the clock, the energy savings from using a plating water cooled chiller can be significant over time.​   Air cooled chillers, due to their lower efficiency, generally consume more energy. The fans used to dissipate heat in air cooled systems require continuous power, and this can add up to a substantial energy cost, especially for high duty electroplating processes. However, for intermittent or low load electroplating operations, the energy consumption difference may not be as pronounced.​   Maintenance​ Air cooled chillers are relatively easier to maintain. They have fewer components compared to water cooled systems. The main maintenance tasks involve cleaning the air filters and checking the fan motors. In an electroplating environment, where there may be contaminants in the air, regular filter cleaning can ensure optimal performance.​   Water cooled chillers, on the other hand, require more extensive maintenance. The cooling tower needs to be cleaned regularly to prevent the build up of scale and algae. The water treatment system, which is essential for preventing corrosion in the pipes and the chiller itself, also needs to be monitored and maintained. In an electroplating facility, where the water used in the cooling system may come into contact with various chemicals, proper water treatment becomes even more critical.​   Cost​ In terms of initial cost, air cooled chillers are often more affordable. Their simpler design and lack of a need for a complex water - cooling infrastructure result in lower purchase and installation costs. This makes them an attractive option for small to medium sized electroplating businesses with budget constraints.​   Water cooled chillers, while more expensive to purchase and install initially, can offer long term cost savings due to their lower energy consumption and higher cooling efficiency. For large scale electroplating operations with high heat load requirements, the investment in a water cooled chiller may be well worth it in the long run.​   In conclusion, the choice between a water cooled and an air cooled chiller in the electroplating industry depends on several factors, including the scale of the operation, available space, energy costs, and maintenance capabilities. For large scale, high heat load electroplating plants, a water cooled chiller may be the better choice despite its higher initial cost. However, for smaller facilities with limited space and lower heat load requirements, an air cooled chiller can provide a cost effective and convenient solution.   Choose Hengde, Choose Perfect Electroplating Chillers!

When it comes to purchasing an industrial chiller, one of the most important decisions you'll face is whether to go with an air cooled chiller or a water cooled chiller. Both options offer effective cooling solutions, but each comes with its own set of advantages and limitations depending on your specific needs, operational environment, and budget. In this blog, we’ll break down the differences between these two types of chillers and help you determine which one is best suited for your business.   What Are Air Cooled and Water Cooled Chillers? Before diving into the pros and cons, it’s important to understand the basic differences between air cooled and water cooled chillers. Air Cooled Chillers: These chillers use the surrounding air to dissipate heat. The condenser is equipped with fans that blow air through the condenser coils to cool down the refrigerant. Water Cooled Chillers: These units use water to absorb and carry away heat from the refrigerant. A cooling tower, often placed outside the building, circulates water to absorb heat and releases it into the atmosphere.   1. Installation and Space Considerations Air Cooled Chillers are generally easier and quicker to install. Since they rely on air for cooling, there's no need for external cooling towers or additional water treatment systems. This makes them an ideal choice for businesses that may have limited space or those that need a more flexible, less complex installation process. They are perfect for smaller facilities or those located in areas where space is limited. On the other hand, Water Cooled Chillers require additional infrastructure, including a cooling tower and water circulation systems. This means they take up more space and may require more time and cost to install. They are typically used in larger operations or facilities with more space available for the required systems.   2. Energy Efficiency When it comes to energy consumption, Water Cooled Chillers generally perform better in larger applications or facilities that require consistent and reliable cooling. They are more energy-efficient in the long run because they tend to operate at a lower temperature, which can reduce overall energy usage. Water’s higher thermal conductivity allows it to absorb more heat, making these chillers better suited for high-capacity cooling needs. However, Air Cooled Chillers can be a more cost-effective solution for smaller systems or applications with less demanding cooling requirements. While they might consume more energy than their water cooled counterparts under heavy loads, they are typically sufficient for moderate cooling needs and may result in lower initial installation costs.   3. Maintenance and Operation Costs Air Cooled Chillers are generally easier to maintain because they do not have the additional components of a cooling tower or water circulation systems. Maintenance tends to be simpler, with fewer parts to inspect and clean. However, because they rely on outdoor air for cooling, they can accumulate dirt and debris, which might require more frequent cleaning of the condenser coils. Water Cooled Chillers require more regular maintenance, especially for the cooling tower, water pumps, and pipes. Additionally, you need to keep an eye on water quality, as scaling, corrosion, and bacteria growth can develop in the system if not treated properly. While maintenance costs can be higher, the overall lifespan and efficiency of water cooled systems can make them more cost-effective in larger, industrial applications.   4. Environmental Impact and Noise Air Cooled Chillers tend to be more environmentally friendly in terms of water consumption since they don’t rely on large amounts of water for cooling. However, they can generate more noise due to the fans used to circulate air through the condenser. This can be a concern in noise-sensitive areas or in places where sound regulations are strict. Water Cooled Chillers, on the other hand, tend to operate more quietly, but they require a constant supply of water, which can be a concern in regions with water shortages or strict water usage regulations. Moreover, the energy consumption of water cooled chillers can indirectly contribute to environmental impact, especially in regions where electricity comes from non-renewable sources.   5. Best Use Cases Air Cooled Chillers are a great choice for: Small to medium-sized operations. Facilities with limited space or where water use is a concern. Locations where installation speed and simplicity are critical. Situations where quieter operation is less important.   Water Cooled Chillers are ideal for: Large industrial applications or facilities with high cooling demands. Locations with ample water supply and space for cooling towers. Operations looking for long-term energy efficiency and higher cooling capacity. Businesses that require quieter operation and can handle the maintenance demands.   Choose an air cooled chiller if you’re operating in a smaller facility, have limited space, or need a simpler, lower-cost solution. Opt for a water cooled chiller if you need more energy efficiency, have the space for additional infrastructure, and are running a large-scale operation with heavy, continuous cooling requirements. At the end of the day, both types of chillers can provide reliable and efficient cooling solutions—it's all about choosing the one that best aligns with your business needs and operational goals.   Hope this helps guide you in your decision-making process!

Choosing a chiller that suits your needs requires considering multiple factors. Here are some suggestions for purchasing a chiller:   1. Determine the cooling capacity of the chiller Determine the cooling capacity of the required chiller based on actual needs. For example, factories, hospitals, etc. have high requirements for cooling capacity and need to choose chillers with larger cooling capacity, such as 200kw chillers, 500kw chillers, 1000kw chillers, 1500kw chillers, etc.; while some small injection molding equipment need to choose chillers with smaller cooling capacity. Such as 5ton chillers, 8ton chillers, 10ton chillers, etc. If you don’t know or are not sure how big an industrial chiller to buy, you can tell the application industry, equipment flow, inlet and outlet water temperature, ambient temperature, refrigerant type, voltage and other special requirements, such as pump flow, pressure requirements, explosion-proof requirements, etc. Hengde Company will recommend an industrial chiller that suits your company’s needs based on all your requirements.   2.Consider the brand and after-sales service of the chiller  The quality and after-sales service of well-known brands of chillers are better, which can ensure the long-term and stable operation of the equipment. At the same time, you should also understand the warranty period and maintenance policy of the chiller. Hengde Company has more than 15 years of experience in the chiller industry, passed ISO9001, CE, SGS and other certificates, and obtained 8 patent certificates. At the same time, Hengde Company has a complete pre-sales and after-sales system, providing 24-hour customer service.

For places with sufficient water source and high cooling requirements, you can choose water-cooled chillers, which generate relatively less noise during operation.   4.Consider the price of the chiller When purchasing a chiller, price is an important consideration. You need to choose a cost-effective device based on your budget and actual needs. But price is not the only factor. The cost-effectiveness of the chiller needs to be comprehensively evaluated based on product quality, technical support and after-sales service.   5. Safety performance and maintenance convenience Check whether the chiller has complete safety protection measures, such as high and low voltage protection, overload protection, leakage protection, etc. High and low voltage protection can prevent the compressor from being damaged under abnormal pressure, overload protection can prevent the motor from burning due to long-term overload, and leakage protection ensures the safety of the operator. Choose a chiller that is easy to maintain. For example, the structural design of the equipment should be easy to disassemble and overhaul, and key components (such as compressors, water pumps, etc.) should be easily accessible. At the same time, the manufacturer should provide detailed maintenance manuals and technical support to facilitate users to perform daily maintenance and troubleshooting.   In short, when purchasing an industrial chiller, you need to consider the above factors comprehensively according to your actual needs and situation and choose the equipment that suits you. At the same time, pay attention to the maintenance and care of the equipment to ensure its long-term stable operation.   Choose Hengde, Choose Perfect Industrial Chillers!

Mold temperature controller, also known as mold temperature machine, was originally used in the temperature control industry of injection molds. Later, with the development of the machinery industry, mold temperature controllers were used more and more widely. Now mold temperature controllers are generally divided into water mold temperature controllers and oil mold temperature controllers. If the selected mold temperature controller matches the temperature requirements of product molding, it can greatly improve the quality of the product and reduce the operating cost of the product. So how to choose a mold temperature controller that matches your process requirements?   1. Heat transfer medium: thermal oil / water. * Water mold temperature controller: Water-type mold temperature controller uses water as a heat transfer medium and is suitable for occasions where the temperature control requirement does not exceed 200°C. Its advantages are high heat transfer efficiency, environmental friendliness, and relatively low cost. * Oil mold temperature controller: Oil-type mold temperature controller uses oil as a heat transfer medium and is suitable for high-temperature occasions. The temperature control range can reach 350°C. Oil type mold temperature controllers are suitable for industries with high temperature control requirements, such as the hot pressing mold industry.   2. Cooling method: direct cooling / indirect cooling * Direct cooling: Direct cooling is suitable for applications that require rapid cooling, such as certain plastic processing processes. This method can quickly reduce the temperature of the heat transfer medium and improve production efficiency. * Indirect cooling: Indirect cooling uses a cooling circuit separated from the main circuit. It is suitable for applications that require more precise temperature control, such as precision mold processing. With an independent cooling circuit, temperature changes can be controlled more finely.   3. Temperature control range: low temperature application / high temperature application * Low temperature application: Taking the plastics industry as an example, due to its relatively low temperature requirements, water mold temperature controllers can meet the requirements. The temperature control accuracy of water temperature controllers is roughly ±1℃, which is sufficient to meet the needs of most industrial application scenarios. * High temperature application: In the case of high temperature applications, such as rubber pressing or metal casting, where high temperature control is required, oil mold temperature controllers are suitable. Oil type mold temperature controllers can not only achieve a wider temperature control range, but also perform better in thermal stability.   4. Mold size and heat capacity Large molds often require mold temperature controllers to have sufficient heating or cooling power to quickly reach and maintain the required temperature. Molds with large heat capacity require more energy during heating or cooling. For example, a large automotive parts injection mold has a much larger heat capacity than a small plastic toy mold, so a more powerful mold temperature controller needs to be selected. The heat capacity can be estimated by calculating the volume of the mold and the specific heat capacity of the material, thereby determining the appropriate mold temperature controller power.   5. Pump flow and pressure The flow of the circulation pump determines the circulation speed of the heat transfer medium (such as water or heat transfer oil) between the mold and the mold temperature controller. Insufficient flow will cause uneven mold temperature and affect product quality. Generally speaking, the flow rate is determined according to the size and complexity of the mold. For small molds, a circulation pump flow of 10-30L/min may be sufficient, while a large and complex mold may require a flow of more than 50L/min. The pressure of the mold temperature controller must be able to overcome the resistance of the pipeline and the resistance inside the mold to ensure the smooth circulation of the heat transfer medium. If the pressure is not enough, local overheating or overcooling may occur. When selecting a mold temperature controller, consider the impact of factors such as the mold's pipeline length, pipe diameter, and number of elbows on the pressure. To meet the needs of different molds.   6. Control system Hengde mold temperature controller adopts imported microcomputer control mode. According to customer requirements, PLC control and RS485 communication function can be selected to achieve automatic management.   7. Safety Check whether the mold temperature controller has perfect safety functions, such as overheat protection, leakage protection, overload protection, etc. For industrial occasions with dangerous environments such as flammable and explosive gases, steam, dust, etc., such as chemical, oil and gas, pharmaceutical and other industries, when purchasing a mold temperature controller, you also need to consider the explosion-proof function and choose Hengde's explosion-proof mold temperature controller.   8. Purchase cost / operating cost Compare the prices of mold temperature controllers of different brands and functions. Under the premise of meeting the application requirements, choose the most cost-effective mold temperature controllers. At the same time, the operating cost of the mold temperature controller, including energy consumption, maintenance costs, etc., should also be considered.   For more questions about the purchase of mold temperature controllers, please visit Hengde's website (www.hengdechiller.com).

Industrial chillers are widely used in industrial refrigeration equipment. Their maintenance is very important to ensure their normal operation and extend their service life. The specific maintenance measures and cycles are as follows:   Daily maintenance of the industrial chillers Wipe the outer shell of the chiller regularly to check for signs of damage, deformation or corrosion. Check whether there are blockages at the inlet and outlet of the chiller, such as dust, debris, etc. If there is a blockage, it should be cleaned in time to ensure good ventilation. Check whether the pipe connection of the chiller is firm and whether there is damage, deformation, or leakage on the appearance. Especially for pipe joints, valves and other parts, ensure good sealing. If there is a problem, the pipe should be replaced in time to prevent leakage or affect the cooling effect. Check the operating status of the chiller, such as whether the compressor, water pump and fan have noise and abnormal sounds. Check the outlet water temperature and return water temperature of the chiller to ensure that the temperature is within the set range. Check the pressure of the system, including the refrigerant pressure and water pressure, to ensure smooth water circulation.   Regular maintenance of the industrial chillers For some important parts of the chiller, special attention should be paid during maintenance: 1. Condenser of the chiller The condenser of the water cooled chiller is prone to scaling, and the condenser of the air cooled chiller is prone to dust accumulation. These two factors will not only affect the heat dissipation effect of the chiller, resulting in a decrease in cooling capacity, but will also affect the increase in the power of the chiller and easily damage the compressor of the chiller. Therefore, the condenser must be cleaned regularly, and the specific maintenance time should be determined according to the actual use environment of the customer.   2. Compressor of the chiller After the compressor of the chiller has been running for 1,000 hours, check whether the compressor refrigeration oil is normal; whether the current is normal during operation; and whether there is any abnormal sound during operation.   After the machine has been used for a certain period of time, due to various factors, the pressure switch needs to be tested to see whether it can alarm high and low pressures. For the electric control box, the dust inside should be blown clean regularly, and the screws should be checked for looseness to avoid damage to the machine.   Attached is the regular maintenance schedule for common parts of Hengde chillers Item Maintenance Period Clean the condenser 3 months Check the chilled water pump 3 months Check the wires (corner insulation)  1 month Check the cooling water supply (water-cooled) 1 week Check various safety protection devices 1 month Check the operating current of the compressor and water pump 3 months   Choose Hengde, Choose Perfect Industrial Chillers!
