Heat recovery with heat pump

The new stand-alone EGAE-RECHP units are dedicated to 100% replacement of room air and its thermal treatment.

They are designed and developed to satisfy four different typical needs of residential and commercial applications:
1.the 100% replacement of room air
2.the energy saving by using a heat recovery system
3.the optimisation of the replacement air heat loads, by a fully automatic microprocessor controlled heat pump system; in particular, the function of heat recovery system increases the e cieny in both cooling and heating performances, ensuring therefore excellent saving in operating costs
4.the optimisation of room heat loads.

EGAE-RECHP unit works with 100% fresh air with total cooling capacity from 5,4 to 23,5kW and total heating capacity from 8,9 to 40,4kW.
