Features & benefits

Single phase heating outputs including 4kW, 6.5kW and 9kW, each rated at -5°C air temperature and 55°C water flow temperature
Featuring sound-reducing features, such as acoustic cotton sound insulation in the casing and twin eccentric cam levers with balancing weights, each heat pump operates with ultra-low sound levels and is Quiet Mark accredited
Designed for installation with the Aerona Smart Controller, the Aerona R290 can be remotely managed and monitored to assist heat pump installers with off-site diagnostic support as well as facilitating weather and load compensation, heating curve adjustments and set-up support
Features built-in PWM circulating pump, DC twin rotary compressor, low- and high-pressure protection controls, discharge temperature protection controls and factory-fitted automatic air vent and 3-bar pressure relieve valve
Uses electronic expansion valve to precisely control the flow of R290 refrigerant into the evaporator as well as a 4-way valve to divert the refrigerant flow for the defrost operation
Incorporates R290 refrigerant safety features including a refrigerant leak sensor and independent ventilation channels allowing for fresh air intake
Units have an anti-freeze protection heater on the plate heat exchanger and heated base tray. Mechanical anti-freeze valves can be used to protect the external system pipework, as glycol antifreeze cannot be used
Multiple condensate drain holes in the base tray and overflow holes facilitate the clear removal of condensate from the heat pumps
