Frames consisting of aluminium profile; double skin (sandwich), 6/10 panels (inner side with galvanized sheet metal, outer side with pre-lacquered sheet metal (RAL 9002) with protective film); insulation through polyurethane foam 23 mm, density 40 kg/m3.
2 EC motors, independently adjustable, external rotor type, with integrated thermal safety cut-outs, with backward curved impellers driven directly by bearings.
Air-to-air heat exchanger, counter-cross flow, made of aluminium, whose high efficiency, certified by Eurovent, exceeds 90% according to EN 308.
100% internal automatic bypass.
2 filters, respectively G4 for the intake air (stale) and F7 for the supply (fresh) air, both mounted upstream of the internal components, in runners fitted with sealing lips to ensure effective airtightness.
Access to filters and internal components with removable panels.
Brackets for fixing to the roof, embedded in the structure.
A special pressure switch continuously monitors the air flow in each fan, indicating possible filter blockage.
A local switch, located on the front panel, allows the unit to be shut down in the event of a fault.
Wired control panel with integrated potentiometers for independent adjustment of the speed of each fan and equipped with a group of lights:
– clogged filters,
• by-pass activation during free cooling mode,
• activation of the external electric preheater (if optionally installed).
