Product Description
R290 DC inverter heat pump is a new energy-saving solution which uses environmentally friendly R290 refrigerant and full DC inverter technology to heat, cool and to produce domestic hot water.
Features of R290 DC Inverter Heat Pump
R290 Refrigerant
R290 refrigerant is a naturally occurring refrigerant, making it environmentally friendly, it has zero Ozone Depletion Potential (ODP=0), meaning it doesn’t contribute to the depletion of the ozone layer; And it has a low Global Warming Potential (GWP=3), meaning it doesn’t contribute significantly to global warming. It is the perfect solution for renovations, where a high water outlet temperature is required.
Full DC Inverter Technology
Guangteng heat pump with R290 refrigerant is the real full inverter heat pump by DC inverter compressor, DC inverter control system and DC inverter fan motor. Inverter technology makes it possible to automatically adapt the compressor and fan rotation speed to the house heating needs and to weather conditions.
High Efficiency A+++ Energy Class
Guangteng R290 DC inverter heat pumps are tested by TUV, achieving the ERP A+++ energy class, the highest energy efficiency.
Smart WiFi Control
With smart WiFi APP control, you can check or control your heat pump anytime, anywhere easily.
