The screw compressor used by the Pengqiang screw water cooled chiller is more reliable than that of the scroll chiller, making it appropriate for high-power operation settings. Large-scale refrigeration can be steadily provided by the screw chiller to aid in the hot object's rapid cooling.
Check if the condenser is clean: A dirty or clogged condenser can impede heat exchange, causing the system to overheat and trigger a high-pressure alarm. Inspect the condenser coils and clean them if necessary to ensure efficient heat dissipation.
Ensure the cooling water flow is normal: Insufficient cooling water flow can lead to inadequate heat removal, resulting in high pressure. Verify that the cooling water pump is functioning correctly and that there are no blockages or restrictions in the water lines.
Verify that the refrigerant level is not too high: Overcharging the system with refrigerant can cause excessive pressure. Check the refrigerant levels and ensure they are within the manufacturer's recommended range. If the levels are too high, you may need to remove some refrigerant to bring it back to the appropriate level.


What is a screw chiller and how does it work?
A screw cooled chiller is an industrial cooling system that uses a screw compressor to remove heat from water or process fluids. It works through a vapor-compression cycle: the refrigerant is compressed, condensed, expanded, and evaporated to continuously absorb and release heat, achieving stable cooling performance for industrial applications.
What are the advantages of a screw chiller?
Screw cooled chillers offer high efficiency, stable operation, and strong cooling capacity. Compared with other types of chillers, they feature lower vibration, longer service life, and better performance under continuous heavy-load conditions, making them ideal for industrial production environments.
What industries use screw cooled chillers?
Screw chillers are widely used in plastics processing, chemical production, food processing, pharmaceuticals, data centers, and large industrial manufacturing plants. They are suitable for any process requiring precise and continuous temperature control.
What certifications do your screw cooled chillers have?
Our screw cooled chillers are manufactured under strict quality standards and comply with CE certification and ISO 9001 quality management system, ensuring reliable performance, safety, and international compliance.
Can screw cooled chillers be customized?
Yes, screw chilled systems can be customized based on cooling capacity, temperature requirements, application industry, and installation environment to meet specific project needs.
