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 immense development potential.
The R290 FULL DC INVERTER Heat Pump meets year-round needs via a 3-way valve:
Normal heat pumps struggle in low ambient temperatures. This R290 unit operates stably and efficiently 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 electric boilers.
5-Inches large LCD touch screen and "Smart Life" App support. User-friendly design facilitates local market expansion with multiple language options.
Choose from Powerful, Smart, Silent, or Vacation modes to balance performance and energy savings based on your specific needs.
Passed TUV ERP A+++ tests for both 35°C and 55°C conditions. With a SCOP up to 4.86, it ensures ultra-high energy efficiency.
Uses three-layer sound insulation cotton and multiple noise reduction technologies for smooth, quiet mechanical-noise-free operation.
Remote data monitoring via Wi-Fi or DUT. Records all operating parameters. Synchronized error reports allow for quick service response, saving time and costs.
