Aquanexa – E Series is an Air to Water heat pump that works on the principle of reverse refrigeration to generate hot water which can be used in closed loop circuits for a number of applications. It has reliable components like a scroll compressor and an expansion valve in circuit through which environment friendly refrigerants like R410a or R134a are circulated. The heat absorbed from ambient air by the refrigerant is further increased by pressurising the refrigerant. This heat is then transferred to incoming water, thus providing hot water at the outlet. Aquanexa E series extracts up to 3.3kW heat from primary air and consumes 1kW of electrical input to give 4.3kW of heat output in the form of hot water.
