Retro Pumps
1 / 5
To reduce carbon emissions and curb global warming, we developed the R290 Full DC Inverter Heat Pump. R290 has a GWP of less than 20 and is recognized as the most eco-friendly refrigerant with massive development potential.
Meeting year-round needs via a 3-way valve: Domestic Hot Water Only, Cooling Only, Heating Only, Heating + DHW, or Cooling + DHW.
Operates stably and efficiently in extremely cold regions. Capable of outputting 75ºC hot water even under low ambient temperatures to ensure house comfort.
Intelligently adjusts operating frequency to maintain constant temperatures. Saves up to 50% energy compared to ON-OFF units and up to 75% compared to traditional electric boilers.
Remote monitoring via Wi-Fi or DUT. Error reports are synchronized for quick solutions, saving communication and maintenance costs for users and providers.
