Compared with traditional chillers, the air source heat pump with
heat recovery can provide hot living water on the basis of
heating/cooling, the desuperheaters make use of the hot refrigerant
vapor leaving the compressor to heat the water through a relatively
small liquid to refrigerant heat exchanger without increasing the
power consumption of the compressor. The dusuperheater can transfer
25 to 30 percent of the energy that would otherwise be dissipated
by the condenser.
Panels and base frame are made from galvanized steel protected with
polyester powder painting to ensure total resistance to atmospheric
Single phase rotary type (mod. 5 only) and 3-phase scroll
