Indoor unit for producing chilled or heated water, with R1234ze refrigerant and twin screw compressors. Adapts to a wide variety of 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 55°C. 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. R515B refrigerant is also available via the configurator.
