Retro Pumps
1 / 5
To reduce carbon emissions and curb global warming, the R290 Full DC Inverter Heat Pump has been developed. Compared to R410A (GWP 2100) and R32 (GWP 675), R290 has a GWP of less than 20 and is recognized as the most eco-friendly refrigerant in the industry.
The perfect performance of the R290 FULL DC INVERTER Heat Pump meets house heating, cooling, and domestic hot water needs throughout the year via a 3-way valve:
Under low ambient temperatures, normal heat pumps are limited. This R290 FULL DC INVERTER heat pump operates stably in extremely cold regions down to -25ºC without EVI technology, maintaining high COP and outputting 75ºC hot water.
Intelligently adjusts operating frequency and water temperature. Save up to 50% energy compared to ON-OFF units and up to 75% compared to traditional boilers. Features Panasonic DC Inverter Compressor and Stepless Fan Motor.
Passed ERP A+++ energy class test by TUV. Reaches A+++ at both 35°C and 55°C water temperatures with a SCOP as high as 4.86.
Connect via Wi-Fi or DUT for remote monitoring. Operating parameters are recorded, allowing for quick error diagnosis and synchronization with service backgrounds to reduce maintenance costs.
