TENESUN low-temperature commercial heat pump water heater variable frequency unit adopts R32 environmentally friendly refrigerant and full DC variable frequency scroll jet enthalpy enhancement technology, operating stably in an ultra-wide temperature range of -35℃ to 50℃. The intelligent control system can precisely regulate water temperature, suitable for various places such as residences, shopping malls, and hotels, providing stable hot water 24 hours a day.

In settings such as swimming pools, aquaculture farms, and hospitals, there is a high and continuous demand for hot water. Traditional heating methods (such as electric heating or boilers) have drawbacks such as high energy consumption and numerous safety hazards.However, TENSUN air source heat pump water heaters utilize free heat from the air, achieving an energy efficiency ratio of 300%-400%, meaning that one kilowatt-hour of electricity can generate the equivalent of 3-4 kilowatt-hours of heat. Furthermore, its operation does not produce open flames or harmful gases, significantly improving safety.
