How EVI Enhanced Vapor Injection technology works

Aurax Evi heat pumps are equipped with 2 Scroll compressors with steam injection (EVI technology) which guarantee high efficiency even at low external temperatures. EVI stands for “economised vapour injection”. The technology involves injecting subcooled refrigerant vapour into the middle of the compression process, a procedure that increases evaporation and significantly boosts capacity and efficiency.

This allows the heat pump to produce water up to 65 °C and to maintain operation to an ambient temperature of - 20 °C.

Features & Benefits

Single refrigerant circuit equipped with 2 high efficiency Scroll compressors, mounted in their own compartment and protected from the ambient air ensuring high efficiency even at low external temperatures/br>
Finned coil source coil with copper pipes and aluminum fin with Blue Fin hydrophilic treatment as standard.

Fans with axial wing-shaped aluminum blades and direct current motor capable of delivering the highest energy efficiency class. These are fixed to the frame via rubber anti-vibration mountings to reduce noise
