Description
• Frames consisting of aluminium profiles; double skin (sandwich), 6/10 panels (inner side with galvanized steel sheet, outer side with pre-lacquered metal sheet (RAL 9002) with protective film); insulation through 23 mm polyurethane foam, 40 kg/m3 density.
• 2 EC motors, independently adjustable, external rotor type, integrating safety thermal cut-outs, with backward curved impellers directly driven by ball bearings.
• Air-to-air, counter cross-flow, aluminium made heat exchanger whose high performance, certified by Eurovent, exceeds 90% according to EN 308 Standard.
• 100% inner automatic by-pass.
• 2 filters, respectively G4 on extracted air (stale) and F7 on (fresh) air supply, both mounted upstream of inner components, on runners fitted with lip seals to ensure effective air tightness.
• Access to filters and inner components by removable panels.
• Feet for floor fixing crimped into the structure.
• Dedicated pressure switch constantly controls the airflow across each fan, showing possible filters clogging.
• A local circuit breaker, mounted on front panel, allows to stop the unit in case of fault.
• Wired control panel with integrated potentiometers to independently adjust each fan speed and equipped with lights group showing:
• clogged filters,
• by-pass activation when in free-cooling mode,
• external electric pre-heater activation (if installed as optional).
