Note:

1.Refrigerating capacity nominal conditions of condenser water inlet temperature 30℃,water outlet temperature 35℃,evaporator water inlet temperature -10℃,water outlet temperature -15℃

2.In order to ensure technology constantly updated, the above parameters are subject to change without prior notice

3.This unit can be customized heat recovery according to the customer request,hot recycled is 25%-30% of unit refrigerating capacity,indicate the hot recycled in custom units.The highest hot water temperature of the heat recovery up to 55 degrees.

Pros of Water cooled Chillers

Water-cooled chillers are generally more efficient than air-cooled chillers
They have a quieter operation than air-cooled systems
They are suitable for both small-scale and commercial-scale cooling
Portable solutions are available for facilities with space constraints

Application

What industries use low temperature chillers?

The uses of industrial low temp chillers are expanding every year. Currently the industries that use low temperatures include: aerospace, medical, pharmaceutical, automotive, defense, plastic manufacturing, chemical, plant oil extraction, food production, and more.

What applications require low temperatures?

Low temperatures are used to: safely store and transport fragile lab samples, temper metals and other materials for extra strength and durability, test materials for use in extreme temperatures/high altitudes/outer space, cool sensitive medical equipment, create superconductors, safely store and transport hazardous chemicals, super chill gasses for plant oil extraction, flash freeze food, and more.
