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. Free pre-sales consultation, technical and operation training, and on-site guidance on the installation and commissioning of the chiller according to the actual needs of customers, so that you have no worries.   3.Consider the installation conditions of the chiller According to the place of use and environment, choose suitable chiller installation conditions, such as power supply, water source, ventilation conditions, etc. For some places with limited space or inconvenient water source, you can choose air-cooled chillers, which are easy to install and occupy a small area. 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.
