Industrial Chillers

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!

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!

Hengde Company, a renowned leader in the industrial refrigeration sector, offers top - notch Industrial Chillers that are crucial for various industrial processes. To ensure the optimal performance and long - term reliability of these chillers, proper installation is of utmost importance. Before commencing the installation, the following preparations are essential.   Pre - installation Preparations 1. The chiller unit should be installed in a dedicated machine room. Measures must be taken to exhaust the heat generated during the chiller unit's operation from the machine room. The ventilation volume should be sufficient to maintain the room temperature below 40°C.   2. The chiller unit should be installed on a non - deformable rigid base or a concrete foundation. This foundation should have a flat surface and be capable of bearing the weight of the chiller unit during operation.   3. There should be drainage measures such as drainage ditches around the chiller unit's foundation with sufficient discharge capacity. This is to facilitate the discharge of water in the system during seasonal shutdowns or maintenance.   4. The machine room should have enough space for the installation, maintenance, and repair of the chiller unit. There should be sufficient space for tube extraction. Also, no pipelines or wire ducts should be laid above the compressor.   5. To ensure the normal operation of electrical components, do not install the chiller unit in places with dust, dirt, corrosive fumes, or high humidity. If such conditions exist, they must be rectified.   Installation Requirements 1. For water-cooled chillers, select a cooling tower that matches the refrigeration capacity of the chiller. When installing the piping of the chiller, install it according to the diameter of the cooling water pipe. Do not reduce the size of the cooling water pipe, as this will cause high - pressure overload, affect the refrigeration effect, and increase power consumption.   2. For air-cooled chillers, they must be installed in a space more than 1m away from the wall to avoid poor heat dissipation, which can lead to high - pressure overload, affect the refrigeration effect, and increase power consumption.   Notes 1. For power load and grounding parts, please construct according to relevant regulations! 2. The chilled water pipes of newly installed chillers must be insulated!   Hengde Company is committed to providing not only high quality Industrial Chillers but also comprehensive technical support and after - sales services.

With the continuous advancement of technology, industrial chillers have found increasingly widespread applications in various industrial fields. They play a crucial role in ensuring the efficient operation of industrial production and enhancing product quality. However, as mechanical equipment, industrial chillers are inevitably prone to certain issues during long - term operation. One of the common problems is equipment corrosion. To effectively prevent the corrosion of industrial chillers and extend their service life, Hengde Company elaborates on the six major common causes of chiller corrosion and provides corresponding preventive measures.   1. Corrosion Issues Caused by Unreasonable Engineering Construction, Design, and Installation Some factories, especially when selling ordinary industrial chillers, cut corners to reduce costs and neglect essential anti - corrosion and anti - rust treatments. Once customers expose the chiller to the outdoor environment for an extended period, the equipment shell is highly susceptible to corrosion. This corrosion risk resulting from the neglect of anti - corrosion measures in the early construction and installation stages can severely affect the normal operation and service life of the chiller.   Preventive Measures: When purchasing equipment, choose suppliers with good reputations and quality guarantees to ensure that the chiller has undergone comprehensive anti - corrosion and anti - rust treatments before leaving the factory, such as spraying high - quality anti - corrosion paint and using corrosion - resistant materials for the shell. Before installation, assess the installation environment and avoid placing the equipment in humid, dusty, or corrosive gas environments. If outdoor installation is unavoidable, build a protective shed to shield the equipment.   2. System Pipeline Corrosion Caused by Incorrect Installation or Abnormal Operation of the Water Processor In water cooled chillers, the cooling water pipeline is a key passage for cooling water circulation. The quality of the water directly determines whether scale and rust will form in the system pipelines. If the water processor is installed improperly or operates abnormally, it cannot effectively treat the water quality, thereby triggering pipeline rust. This not only reduces the heat exchange efficiency of the chiller but may also lead to pipeline blockages, affecting the stable operation of the entire system.   Preventive Measures: Before installing the water processor, strictly follow the product manual for correct installation and conduct debugging after installation to ensure its normal operation. Regularly maintain and service the water processor, checking whether all its functions, such as filtration, sterilization, and descaling, are normal. Meanwhile, regularly test the cooling water quality and adjust the operating parameters of the water processor or replace consumables like filter elements in a timely manner according to the water quality conditions.   3. Insufficient Filtration of Fine Impurities by Y - type Filters Currently, the commonly used dirt removers in industrial chillers are mostly Y - type filters. They have the advantages of easy installation and convenient dirt cleaning and can conduct preliminary rough filtration of mechanical impurities, iron filings, and sand grains. However, their filtration effect on tiny impurities is unsatisfactory. As the unit operates for a long time, the condenser is extremely likely to accumulate dirt, sludge, and other impurities. These deposits not only reduce the heat transfer performance of the condenser but may also accelerate the equipment's corrosion process due to the formation of a local corrosion environment.   Preventive Measures: Based on the Y - type filter, add a precision filter to conduct more refined filtration of tiny impurities. Regularly clean and maintain the Y - type filter and the precision filter, and promptly remove the impurities inside the filters. At the same time, regularly clean the condenser. Chemical cleaning or physical cleaning methods can be used to remove the dirt and deposits inside the condenser and maintain its good heat transfer performance.   4. Absence of a Quick Drain Valve in the Chilled Water System The quick drain valve plays an important role in draining in the chiller or chilled water system. It has a simple structure, good sealing performance, small size, and light weight, and is especially suitable for regular draining of the system. It also has the advantages of corrosion resistance, impact resistance, and long service life. However, currently, many industrial chiller end plates in enterprises do not have a quick drain valve installed, which is likely to cause system pipeline corrosion. During the daily operation of the chiller, it is recommended to open and close the drain valve three times a week to ensure smooth system drainage and maintain the good operation of the system.   Preventive Measures: For chilled water systems that have not installed a quick drain valve, install a quick drain valve that meets the system requirements as soon as possible. In daily use, strictly follow the recommended operation frequency to open and close the drain valve to ensure that impurities and dirt in the system are discharged in a timely manner. At the same time, regularly check the sealing performance and working status of the drain valve and replace it promptly if it is damaged.   5. Absence of a Water Meter in the Cooling System Makeup Water Pipeline In the water quality treatment process of the cooling system, chemicals and bactericides are usually used to kill fungi, microorganisms, and remove various dirt inside the pipeline. The dosage of the chemicals needs to be accurately adjusted according to the makeup water volume and the system water volume. If there is no water meter installed in the cooling system makeup water pipeline, it is impossible to accurately measure the makeup water volume, resulting in inaccurate chemical dosing. Excessive dosing may cause chemical corrosion of the pipeline, while insufficient dosing cannot effectively inhibit the growth of microorganisms and the formation of dirt, also triggering system pipeline corrosion problems.   Preventive Measures: Install a water meter with appropriate accuracy in the cooling system makeup water pipeline to accurately measure the makeup water volume. According to the system water volume and makeup water volume, accurately calculate the dosage of the chemicals according to the chemical usage instructions. At the same time, regularly test the water quality of the cooling system and adjust the dosage and type of the chemicals in a timely manner according to the test results to ensure that the water quality is in a good state.   6. Corrosion of the Equipment Surface by Acidic and Alkaline Gases in the Environment During factory production, some special gases, such as acidic and alkaline gases, are inevitably generated. These gases flowing in the environment can cause erosion damage to the equipment surface. Therefore, when selecting a chiller in an environment with such special gases, it is necessary to explain the situation in detail to professionals in advance so that explosion - proof and corrosion - resistant materials are preferentially selected for the production of the electrical control box or evaporator pipeline. This can effectively prevent the equipment from being corroded and damaged by acidic and alkaline gases during the later operation.   Preventive Measures: During the equipment selection stage, fully consider the gas components and concentrations in the working environment and choose chillers with corresponding protection levels and corrosion - resistant properties. For installed equipment, gas purification devices can be set up around the equipment to reduce the concentration of acidic and alkaline gases in the environment. Regularly inspect and maintain the equipment surface. If there are signs of corrosion, promptly carry out repair and protection treatments, such as repainting anti - corrosion paint.     With the rapid development of industry and the continuous emergence of new materials and new processes, the application scenarios of industrial chillers are becoming increasingly diverse, which increases the risk of equipment corrosion. Here, Hengde earnestly reminds industry friends that for industrial chiller equipment, real - time maintenance and customized servicing remain the keys to reducing corrosion and extending the service life. Only through scientific and reasonable maintenance measures can industrial chillers operate continuously and stably in complex industrial environments and provide reliable support for industrial production.
