2 Subcritical Secondary Coolant System Usually, secondary coolant system uses brine circulation system as the refrigeration medium, but through the high density characteristic of liquid CO2, and its better thermodynamic property during medium temperature refrigeration process, R744 (CO2) is very suitable for replacing the original E.G, P.G secondary refrigerant. This refrigeration system first works with HFC refrigerant compressor to start cooling process, and through evaporator, it cools down (condense) R744 (CO2) on the secondary side, then a pump will distribute low temperature R744 (CO2) through whole system. KAORI C series is suitable to be the evaporator of this system, in addition of increasing thermal conductivity, KAORI C series are also smaller model size, and higher and safer pressure resistance. To satisfy customers in different industries, KAORI provides various kinds of connectors for customization, at a reasonable price which benefits customers to attain lower assembling costs.

KAORI C series high pressure heat exchanger could be used/Installed for several different applications, such as gas cooler, economizer, SLHE (suction line heat exchanger) and intercooler, KAORI C series is the best solution for R744 (CO2) applications.
