air source heat pump with heat recovery

Compared with traditional chillers, the air source heat pump with heat recovery can provide hot living water on the basis of hea

STRUCTURE

Panels and base frame are made from galvanized steel protected with polyester powder painting to ensure total resistance to atmospheric agents.

HERMETIC COMPRESSORS

Single phase rotary type (mod. 5 only) and 3-phase scroll compressor (mod.8.5-30), with thermal overload cut-out and crankcase heater mounted on rubber vibration isolators. 

AXIAL FANS

External rotor type axial fans, equipped with single phase direct drive motors, low noise 6 poles, protection level IP54, provided with a protective outlet grille.

EVAPORATOR

High efficiency tube in tube type, factory insulated with flexible close cell material.

CONDENSER

Coils are consisting of seamless copper tubes mechanically expanded into blue hydrophilic aluminum fins, protected with flexible plastic grill.

DESUPERHEATER
