Fan:
High efficiency low noise electric motor with imported top tier maintenance free bearings is adopted, together with new developed centrifugal blower with air flow rate adjustable by 3-stage. The designed fan service life is up to 100,000 hours. The Power input is 220V/50Hz or 380V/50Hz. 110V power is optional per customer’s request.

Heat Exchanger:
CPRF-A series adopts primary grade copper tube and double-sine wave aluminum fin, with hot water as the heating media. The heating convector features long service life, compact in size but large in heating capacity, high heat transfer efficiency, high corrosion resistance and high pressure resistance. 

Filtration Device：
Coarse filter will be included on the air inlet side to avoid dust accumulation within the heat exchanger to cause poor air flow. The filter is made by either synthetic polyester fiber (PET) or aluminum alloy mesh net.
