The chilled water pump of the chiller must not operate when there is no water in the water tank. 2. Try to avoid continuous switching of the operation switch. 3. When the chilled water temperature of the chiller reaches the set temperature, the compressor will automatically stop running. This is a normal phenomenon. 4. The temperature switch should be set above 5°C to prevent the evaporator from freezing (except for low - temperature units). 5.To ensure the best cooling effect and keep the chiller in optimal condition, regularly clean the condenser, evaporator, and water filter of the industrial chiller.   II. Electrical Precautions 1. Only after the unit is shut down and the power is turned off can the industrial chiller be cleaned. Otherwise, there may be a risk of electric shock or injury. 2. Do not directly rinse the chiller with water, and do not perform maintenance when the chiller is in operation. 3. Do not use steel wire or copper wire to replace the circuit breaker. Use the correct - specification fuse to avoid damaging the industrial chiller. 4. If a fault alarm occurs, immediately shut down the unit. Restart it only after the fault is eliminated, or promptly notify the maintenance personnel for handling. Continuing to use the chiller in this situation may cause electric shock or fire accidents. 5. Warranty work can only be carried out by professionals. Before removing the electrical wiring device, all power sources must be cut off.   III. Warnings 1. Never twist or pull the wires of the controller to avoid damaging the controller and causing malfunctions. 2. Never wipe the controller with benzene, thinners, or chemicals. Otherwise, it may cause discoloration or component malfunctions. To clean it, first soak a cloth in water containing a neutral detergent, wring out the water, wipe the controller, and then dry it with a dry cloth. 3. Never apply excessive force to the operation screen or connection parts to avoid color changes.   Hengde Company always pays attention to the customer - use experience.

As a leading enterprise in the industry, Hengde Company relies on the Industrial chiller to play a crucial role in various industrial production processes. It can precisely control the temperature and ensure the stable operation of production equipment, which is a key link in ensuring production efficiency and product quality. However, during long - term use, the compressor of the industrial chiller may issue some fault alarms, which not only affect the normal operation of the equipment but may also lead to production stagnation. To help you solve problems quickly and effectively, the following details the common high pressure alarm and low pressure alarm faults of the Industrial chiller compressors of Hengde Company and the corresponding solutions.     High - Pressure Alarm of Industrial chiller Compressor 1. The condenser is dirty and blocked. Solution: Clean the condenser, keep the air temperature below 40°C / keep the cooling water below 35°C.   2. The high - pressure switch trips. Solution: Press the reset button of the high - pressure switch and restart the compressor.   3. Over - charging of refrigerant. Solution: Check whether the refrigerant charging amount is excessive.   4. Cooling water pump failure. Solution: Repair or replace the water pump.   Low - Pressure Alarm of Industrial chiller Compressor 1. Insufficient refrigerant or refrigerant system leakage. Solution: Check whether the system lacks refrigerant or whether there is leakage in the system pipelines.   2. Insufficient water flow or system shortage causes the evaporator to freeze. Solution: Check whether the water tank is short of water and whether the valve is fully opened. If the evaporator freezes, drain the water completely and then add warm water to melt it. Do not knock the ice with hard objects, as piercing the copper tube will damage the compressor!   3. Chilled water pump failure or pipeline blockage. Solution: Check the chilled water pump and pipeline system.   Hengde Company has always been committed to providing customers with high quality Industrial chiller equipment and complete after - sales services.

As a leader in the refrigeration equipment industry, Hengde has leveraged its extensive technical expertise and innovative R&D capabilities to provide efficient and reliable industrial chiller solutions across a range of industries. Among these, application in the plastics industry stands out. In the complex and temperature-sensitive production processes of plastic manufacturing, industrial chillers play an indispensable role and have become key equipment for improving product quality and production efficiency.     1. Plastic Molding Mold Cooling In the plastic molding process, the cooling phase of the molds has a significant impact on both product quality and production efficiency. Hengde chillers come into play by precisely controlling mold temperatures. With efficient heat exchange mechanisms, the chillers quickly remove heat from the molds, accelerating the plastic curing process. This not only significantly reduces cooling time, allowing for faster mold release, but also greatly improves production efficiency. Furthermore, Hengde chillers ensure even distribution of mold temperature, preventing surface defects such as flow marks or stress concentration caused by uneven cooling. This results in enhanced product appearance, dimensional accuracy, and prevents deformation and shrinkage during cooling, ensuring products remain stable and meet high-precision manufacturing standards.   2. Plastic Processing Machinery Injection Molding Machine: Injection molding machines are crucial in plastic production. Hengde chillers are specifically designed for injection molding machines, providing vital support for ensuring high-quality injection molding operations. During the injection process, the chiller machine works in tandem with the injection machine to continuously cool the mold, ensuring even heat dissipation of the plastic product. This guarantees high-quality production and meets the high-precision requirements of complex injection-molded products.   Extrusion Molding Machine: For extrusion molding machines, Hengde chillers provide effective cooling for the extruder and mold, precisely controlling processing temperatures. This ensures dimensional stability of the extruded products and eliminates size deviations caused by temperature fluctuations. Additionally, it improves surface finish, resulting in smoother, higher-quality plastic products that meet premium product standards.   Blow Molding Machine: For blow molding and thermoforming equipment, Hengde chillers provide stable temperature control to create the ideal thermal environment for product formation. During blow molding, precise cooling ensures even wall thickness of the molded products, improving product strength. In thermoforming, quick and uniform cooling allows products to set faster, increasing production efficiency while ensuring consistent product quality.   3. Other Plastics Processing Industries In addition to core applications in molding and processing machinery, Hengde chillers also play an essential role in the production lines of plastic pipes, cable trays, cables, and other plastic profiles. Once these products are molded, the chiller quickly cools them, ensuring that they maintain stable physical properties during the cooling process.    Hengde Industrial Chiller In Plastic Processing: When selecting a industrial chiller, Hengde’s professional team helps plastic manufacturers consider various factors. Based on production scale and thermal load requirements of the plastic processing, we precisely calculate the required cooling capacity.
