COP-Booster

CoP Booster

Improved CoP

• Optimised with refrigerant 410a• Ensures minimum overheat of refrigerant gas• Compressor protected (no liquid)

EUSEW 11-15 April 2011

High efficiency heat pump systems  – from best practice to mainstream | 14-04-2011 | Sustainable Energy Week | Brussels

Improved CoP

Oversized heat exchanger• Larger Casing• Less and shorter defrost cycles• Increased CoP• Lower sound emissions due to reducedairflow

High efficiency heat pump systems  – from best practice to mainstream | 14-04-2011 | Sustainable Energy Week | Brussels

Optimised Heat Exchange

Improved CoP

Water source heat pump (open loop)• No external heat exchanger required toprotect the heat pump• Direct use of ground water Safe due tospecial designed stainless steal heatexchanger•

Better SCoP
