Description

WFN is an indoor unit for producing chilled or heated water, with R134a refrigerant and twin screw compressors. It adapts to various load conditions thanks to precise tempera- ture control, produces chilled water up to 16°C (processed water, evaporator side) and can also be used with a heat pump with a processed water temperature (on the con- denser) of up to 55°C. Both heat exchangers (source side and system side) are of the shell and tube type. The electronic expansion valve is a standard on all the sizes and ensures excellent flow regulation and accurate temperature control, even with partial loads.
