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.025 only) and scroll type (mod.030÷035) compressors, 3-phase scroll compressor (mod.040÷120), with thermal overload cut-out and crankcase heater mounted on rubber vibration isolators.

Models 030÷035 are available also with 3-phase scroll compressor and mod.040 with single phase scroll compressor.

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
