The cold heat change was mad the fluid separator the function is the cold intermediary and the low pressure. The low temperature which the high pressure, the high temperature needs to cool needs the cold intermediary two pipelines which the temperature evaporates to concentrate in a vessel, mutually by high low temperature conduction. Enable the cold intermediary which needs to cool to obtains the low temperature, needs to heat up the cold intermediary obtains the high temperature, after passes through the cold changer function, the system efficiency will be able to the big promotion, to be able achieve the best refrigeration effect
Feature
1. Sturdy steel shells for long life
2. Corrosion resistant epoxy powder paint finish
3. Maximum working pressure: 28bar
4. It is strongly recommended to assemble PRR series cooling & heating exchanger to the refrigeration system whose evapour temperature lower than -15℃
5. Products are compatible with HFC, CHFC, HFC as well as with their associated oils and additives,
