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 in the industry.
The system meets annual needs for house heating, cooling, and domestic hot water (via 3-way valve). Modes include DHW Only, Cooling Only, Heating Only, and Priority modes.
While normal heat pumps struggle in low temperatures, this Full DC Inverter system 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. Saves up to 50% energy compared to ON-OFF units and up to 75% compared to traditional boilers.
Features a 5-inch large LCD touch screen and "Smart Life" Wi-Fi App support for remote monitoring and local language options.
Equipped with three-layer sound insulation cotton and noise reduction technology. The IoT cloud platform allows remote data monitoring and rapid error reporting to ensure quick technical support.
