EVI Heat Pump
Advantages
-
EVI Technology: Adopting the most advanced low temperature enhanced vapors injection compressor technology which can help heat pump work steadily even at temperature of -25°C.
-
Wide range of temperature: EVI heat pump can work from -25°C to 43°C. Widely used in different environment.
-
Higher heating capacity: Using enlarging evaporator extracting more heat energy from air, will increase COP.
-
Automatic start-up anti-freezing protection: When the ambient is below 0°C, the unit is in stand-by mode more than 30 minutes, automatic anti-freezing device will be started up, so that the unit will be protecting in lower temperature.
