Water-cooled Screw chiller

Water-cooled Screw chiller is a type of refrigeration equipment used for cooling large buildings or industrial processes. It operates by using a screw compressor, which is known for its efficiency and reliability.

Water-cooled Screw chiller

◎ Water is used to dissipate heat and be used with cooling water towers

◎ Screw compressor, larger cooling capacity

◎ High efficiency condenser

◎ Stable operation, power saving and durable

◎ Multiple security protection

◎ Working cooling temperature adjustable from 5-35 degrees

Note: 1. nominal cooling capacity calculated according to:lnlet/outlet chilled fluid temperature : 12℃ /17℃ ,Inlet/outlet cooling water temperature: 30℃ /35℃ . 2. Working condition:The temperature range of chilled fluid is from 5℃ to 30℃ ,The temperature difference between inlet and outlet chilled fluid is from 3℃ to 8℃ ,The temperature range of cooling water from 18℃ to 30℃ Temperature difference between inlet and outlet cooling water is from 3.5℃ to 10℃ .We reserve the right to modify the above information without further notice
