WFI is a dual-circuit or triple-circuit indoor unit for producing chilled or heated water chiller charged with R134a gas and twin screw compressors. The units are designed with two or three twin-screw compressors, one of which has an inverter, to provide high yield at full load, and very high efficiency at partial loads, with the increasingly optimised compression yield of the inverter compressor. The chiller adapts to various load conditions thanks to precise temperature 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 condenser) of up to 60 °C depending upon the models. Both heat exchangers (source side and system side) are of the shell & 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. It is available in 2 versions: Standard and High efficiency.
