Note: 1.Rated cooling capacity is based on: the chilled water inlet and outlet temperature 12℃/ 7℃; cooling air inlet and outlet temperature 30℃/35℃.

2.Scope of work: chilled water temperature range: 5℃ to 30℃; chilled water inlet and

outlet temperature difference: 3℃ to 8℃.

Best cooling temperature range: 15-30℃; recommend to use in ambient temperatures below 38℃; cooling air inlet and outlet temperature difference: 8℃ to 10℃.

The above chillers can be customized according to customers' requirements.

Specifications and dimensions above are subject to change without notice.

Advantages of Water-cooled screw chiller:

Water-cooled screw chillers are applied to wide fields: Such as plastic, electroplating, electronics, chemical, medical, cleaning, food, metallurgical and other industries, which can cool off their facilities. It also provide high-performance water systems for shopping malls, office buildings, hotels, hospitals, residential villas and other places, which create a quiet and comfortable living and working environment our customers.

The less common open loop industrial chillers control the temperature of a liquid in an open tank or sump by constantly recirculating it. The liquid is drawn from the tank, pumped through the chiller and back to the tank. In industrial water chillers is the use of water cooling instead of air cooling. In this case the condenser does not cool the hot refrigerant with ambient air, but uses water that is cooled by a cooling tower. This development allows a reduction in energy requirements by more than 15% and also allows a significant reduction in the size of the chiller, due to the small surface area of the water-based condenser and the absence of fans. Additionally, the absence of fans allows for significantly reduced noise levels.
