Application :
Cryogenic water chiller is a special refrigeration equipment which provides cryogenic refrigerant. It is suitable for various occasions with medium and low temperature cold source requirements. It is widely used as a process cold source for non-ferrous metallurgy, chemical and pharmaceutical intermediates, petrochemical industry, grain and oil, beverage and food, machinery, medicine, electronics, air separation and other production and processing.
Cryogenic water chiller is a new generation of cryogenic equipment specially designed for special industry requirements. Its temperature range can be adjusted from 30 degrees to 60 degrees below zero. The refrigeration range is 10 – 1000KW. The cryogenic chillers are divided into three series of water supply units with high, medium and low temperature according to the cooling range.
1. Standard chiller: It can provide 3-35 ~C chilled water, or use ethylene glycol solution as refrigerant. It can provide -5-5 ~5 ~C process chilled water solution. It can be used as the process cold source for ice storage, low temperature air supply, central air conditioning and other production processes. At the same time, according to the user’s requirements, the unit can be specially designed to provide screw chillers with large temperature difference.
2. Medium temperature chiller: the outlet water temperature is – 5 ~45 C, using imported semi-closed screw compressor unit (with economizer); low temperature ethylene glycol solution or saline solution can be provided from – 5 ~45%. It can be used as a cold source for chemical industry, medicine, cold storage, ice rink and other processes.
3. Cryogenic screw chiller: The effluent temperature is – 45 ~110 C, which can provide – 45 ~110 ~alcohol or dichloromethane solution frozen water. Using binary cascade refrigeration system or ternary cascade refrigeration system, the operation is stable and the energy efficiency ratio is high.
