EVI STRONG HEATING TECHNOLOGY

WHAT’S EVI TECHNOLOGY?

EVI stands for Enhanced Vapor Injection and is a technology used on our cold climate heat pumps to achieve higher performance at lower temperatures. An EVI heat pump uses a 3rd smaller internal plate heat exchanger called an Economizer within the refrigeration cycle.

Higher COP PERFORMANCE

Using EVI heat pump technology, we are able to overcome the limitation of maximum flow temperature that other cold climate heat exchangers encounter. EVI Heat Pump technology allows more heat to be delivered resulting in a better COP at much lower temperatures. The EVI technology increase performance efficiency by 27-30%.

WIDE OPERATING TEMPERATURE RANGE

Wide operating temperature range. even in cold climate ranging from -20℃ to 45℃, and can work safely and reliably at ambient temperature as low as -30℃ with Wet Injection.
