Enhanced Vapor Injection is a technology specifically designed for cold climates, delivering superior performance even in extremely low temperatures.

Utilizing a DC inverter enhances the efficiency of the heat pump’s operation. Studies indicate that the working efficiency of a DC inverter compressor surpasses that of an AC inverter compressor by 10% to 30%.

At the same time, EVI Technology allows the heat pump to absorb more heat from ambient air at lower climatic conditions, guaranteeing consistent performance even in extreme ambient temperatures as cold as -25°C.

Another benefit that DC inverters present is the reduction of vibration and therefore noise levels. Through adaptive intelligent torque compensation vibration suppression technology, noise emissions are controlled and reduced by 5dB(A). 

Elevate your expectations as the innovative EVI technology raises the bar, allowing the water outlet temperature to reach up to 65°C. Unleash a new whole set of possibilities for your heating needs.
