Aermec WFN, la pompa di calore con gas R134

WFN is the series of indoor heat pumps using R134 refrigerant, designed for producing chilled or heated water. It is 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.

WFN 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 55 °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.

WFN is designed with 2–3 refrigerant circuits to ensure maximum performance even under partial load conditions and to guarantee continuous operation in the event one circuit stops. All units are equipped with screw compressors and tube-bundle heat exchangers on both the plant and source sides.

It is also available as a configuration option with refrigerant R513A (XP10).

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