To reduce carbon emissions to the environment 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 with the highest development potential in the industry.
The R290 FULL DC INVERTER Heat Pump meets all-year house needs via a 3-way valve:
The unit operates stably and efficiently in extremely cold regions down to -25ºC without EVI technology, maintaining a high COP and outputting 75ºC hot water for comprehensive home climate control.
Utilizing full DC inverter technology, the unit intelligently adjusts operating frequency and water temperature. It saves up to 50% energy compared to ON-OFF units and up to 75% compared to traditional electric heat pumps.
Key Components: DC Inverter Compressor, Stepless DC Fan Motor, DC Water Circulation Pump.
5-Inches large LCD touch screen and "Smart Life" Wi-Fi App support multiple languages. This user-friendly design facilitates easy local operation and remote management.
Choose between Powerful, Smart, Silent, and Vacation modes to optimize energy consumption based on your specific daily needs.
Passed the TUV energy class test, reaching A+++ at both 35°C and 55°C. With an SCOP as high as 4.86, it ensures ultra-high efficiency.
Featuring three-layer sound insulation cotton combined with advanced noise reduction technology, the unit operates smoothly and quietly without mechanical disturbance.
Remote monitoring via Wi-Fi or DUT allows for real-time data tracking. Error reports are synchronized for rapid solutions, saving maintenance costs and time.
