The Aerona³ R32 inverter driven air source heat pump has expanded to include models from 6kW up to 17kW. As its name suggests, this heat pump uses the more environmentally friendly R32 refrigerant which makes for a cleaner heat pump while still delivering excellent performance. The Aerona³ R32 heat pumps are Grant’s greenest heat pumps yet. Each model also incorporates the familiar features that engineers have come to associate with the Grant Aerona brand. All of the Aerona³ R32 heat pumps are single phase, DC inverter driven ASHPs incorporating in-built weather compensation and a base tray heating element to prevent ice formation. Monobloc in design, the Aerona³ R32 is suitable for use with S-Plan heating control systems and is simple to work with for installation and maintenance. The Aerona³ R32 models have a compact footprint and operate with low noise levels. They therefore have minimal impact on their surrounds both aesthetically and acoustically, something which is of great benefit to end-users.
