Pompa di calore WFI per grandi utenze

WFI is the series of indoor heat pumps using R134 refrigerant, designed for the production of chilled or heated water and engineered to meet the air conditioning needs of residential/commercial complexes or the refrigeration requirements of industrial facilities. Compact and flexible, it adapts to various load conditions thanks to precise thermostatic control, and is available in both the Standard (°) and High Efficiency (A) versions.

WFI can produce chilled water down to 16 °C on the evaporator side. It is also suitable for heat pump applications, with condenser water temperatures of up to 60 °C depending on the model. The unit equipped with the optional electronic thermostatic valve Z can even produce chilled water at negative temperatures, ranging from −8 °C to 10 °C.

WFI is designed with 2–3 refrigerant circuits to ensure maximum performance even at partial loads and to guarantee continuous operation in the event one circuit stops functioning.

All units are equipped with an inverter compressor paired with an on/off compressor (for dual-circuit models) or two on/off compressors (for tri-circuit models), using refrigerant R134a. The refrigerant R513A (XP10) is also available as an option.

The unit features microprocessor control, complete with a keypad and LCD display that allows for easy monitoring and adjustments through a multilingual menu. The control system includes comprehensive alarm management and logging.

Hot water production on the condenser side up to 60°C.
Chilled water production on the evaporator side down to -8°C.
Also available with R513A refrigerant.
Cooling capacity: 670 – 2406 kW
