400Kw New low price plastic injection molding use air cooled screw cooling water chiller

1.Working Principle Of Our air cooled water chiller

Working principle as the picture display, the main parts include hermetic scroll compressor, condenser, dry filters, expansion valve, evaporator, water pump, protection and etc.
When refrigeration, compressor suction the low temperature and low pressure refrigerant from evaporator to cylinder; after the compression become high temperature and high pressure gas discharge into the condenser; then after the air(air cooled chiller) or water(water cooled chiller) heat exchange, the heat was taken away by air or water become high temperature and high pressure liquid refrigerant; through the filter into the expansion valve, after expansion become low temperature and low pressure refrigerant, and then into the evaporator; suction the heat from water or air in evaporator, reduce the temperature of water/air to satisfy the refrigeration effective; the chilled water send to user equipment by pump, to satisfy the user’s refrigeration need. The refrigerant gas passes through the compressor suction again into the cylinder after gasification in the evaporator; this work is keep cycle then continuous to producing chilled water.

2.Features Of air cooled water chiller

(1). Superior compressors from famous brands(Bitzer,Hanbell,Refcom),high efficient shell condensers and evaporators with excellent cooling effect but low electric consumption.
(2). Equipped with precise electric temperature controller which is easy for operation and is capable of precisely controlling the water temperature from 7°c to 35°c.
(3). Stainless steel water tank avoid s rust and can be easily maintained or cleaned.
(4). Current-overload protector, high-and-low pressure switches, electronic time delayer,fault display system.Four main security systems to ensure safe operation.

(5). Single, double or quadruple compressors combination available which is economic and efficient.
(6). Applicable for cooling field in modern industry without influence from environmental temperature as the necessary equipment.
