water cooled water chiller, hermetic piston compressor, shell and tube condenser, dry-type shell and tube heat exchanger - details see: https://www.machineto.com/industrial-water-cooled-water-chiller-10243244

Features of water cooled water chiller

1.application of economizer

Increase the supercooling degree of liquid refrigerant and improve unit refrigerating capacity

2.reliable functional components

Adopting newly high efficiency heat exchange tube to make dry expansion evaporator and condenser with high heat transfer efficiency, so it can improve refrigerating capacity of the unit and reduce input power;

Solenoid valves, oil separators, electric components etc are all world famous brand with high quality and long service life.

3.application of environmental friendly refrigerant

Various refrigerant can be used, like HFC404A, HFC134a and so on

4.various secondary refrigerant can be used

Glycol water solution, propanediol water solution, ethanol etc, or design the evaporator as an anti-corrosive one, so that Calcium chloride water solution can be used;

5.application of high efficiency oil separator

Reduce lubricant which flow in evaporator, so it can improve the heat transfer efficiency of evaporator

6.application of injection technology

Injecting liquid refrigerant to the compression chamber of a compressor can reduce discharge temperature efficiently
