WFGI, la pompa di calore Aermec reversibile lato acqua

WFGI is the series of indoor heat pumps using R1234ze refrigerant, designed for the production of chilled or heated water, engineered to meet the air conditioning needs of residential/commercial complexes or for refrigeration in industrial facilities. Compact and flexible, it adapts to various load conditions through precise thermostatic control.

It is available in both Standard (°) and High Efficiency (A) versions.

WFGI can produce chilled water down to 20 °C on the evaporator side. It is also suitable for heat pump applications with condenser water temperatures up to 65 °C, depending on the model. The unit with the optional electronic thermostatic valve Z can also produce chilled water at negative temperatures, from −8 °C to 10 °C.

WFGI 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 R1234ze. The refrigerant R515B is also available as an option, with performance remaining consistent regardless of the selected refrigerant.

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