Eco-friendly R32

The refrigerant used in the Evotherm ETI Series is safer for the environment. R32 refrigerant has a 30% lower Global Warming Potential rating than traditionally used refrigerants like R410A.

Quiet Operation

The Evotherm ETI Series heat pump utilises soft-starting brushless DC electric motors for quiet fan operation. With operation noise levels as low as 39dBA.

Touch Screen Control

The Evotherm ETI provides complete control through its backlit user-friendly LED touch screen, allowing you to easily select operating modes, set temperature, schedule timers and run diagnostics at a touch.

Soft-Start Feature

Full-inverter control enables soft-starting, stepless operation of the fan and compressor motors, eliminating harsh current spikes and allowing precision control of motor speeds.

COP of Up To 14.5

By utilising a full-inverter, stepless drive system, the ETI’s efficient technology can increase the Coefficient of Performance (COP) up to a rating of 14.5.
