Standard unit technical specications
Compressor
Hermetic rotary compressor with gas compression in the crankcase, direct suction, no oil heater. It is mounted on antivibration rubber pads. Includes oil
feed.
Fitted on rubber antivibration mounts and complete with oil charge and suction lter.
Structure
Size 70-120:
Supporting structure made with RAL 9001 prepainted sheet aluminium metal that ensures excellent mechanical features and high long-term resilience
against corrosion. The entire ventilating area is covered with anti-condensation and sound-proof material.
Size 200-650:
Structure made entirely from “aluzink” plate that guarantees excellent mechanical characteristics and high corrosion strength over time. The ventilating
section is completely lined with anti-condensate and soundproong material.
Internal exchanger
Exchanger for the ambient air pre-treatment
Finned exchanger, made from copper pipes arranged in staggered rows and mechanically expanded for better adherence to the collar of the ns. The ns
are made from aluminium with a special corrugated surface, set a suitable distance apart to ensure maximum heat exchange eciency.
The surface of the 70-120 ns of the coils has been subjected to an hydrophilic treatment to make it easier to discharge condensation and reduce frost.
External exchanger
Exchanger for the energy recovery of the extract air
Finned exchanger, made from copper pipes arranged in staggered rows and mechanically expanded for better adherence to the collar of the ns. The ns
are made from aluminium with a special corrugated surface, set a suitable distance apart to ensure maximum heat exchange eciency.
The surface of the 70-120 ns of the coils has been subjected to an hydrophilic treatment to make it easier to discharge condensation and reduce frost.
