Retro Pumps
1 / 5
To reduce carbon emissions to the environment and curb global warming, the R290 Full DC Inverter Heat Pump has been developed. Compared to R410A refrigerant with a GWP of 2100 and R32 with a GWP of 675, R290 has a GWP of less than 20 and is recognized by the industry as the most development potential and eco-friendly refrigerant.
Under low ambient temperature, the performance and stability of normal heat pumps are limited. This R290 FULL DC INVERTER heat pump operates efficiently in extremely cold regions of -25ºC without EVI technology, maintaining a high COP and outputting 75ºC hot water.
Full DC inverter technology intelligently adjusts the operating frequency and controls water temperature to keep the room constant. It saves up to 50% energy compared to ON-OFF units and up to 75% compared to traditional electric heat pumps.
The IoT cloud management platform connects via Wi-Fi or DUT for remote monitoring. It records all operating parameters. If an error occurs, reports are synchronized to the service background for quick solutions, saving communication and time costs.
