Description
                    •	Frames consisting of rounded aluminium profiles with built-in, polyamide made, spacers for class TB2 thermal break; corners made of reinforced polyamide; double skin (sandwich), 10/10 panels (inner side with galvanized steel sheet, outer side with pre-laquered metal sheet (RAL 7035) with protective film); insulation through 50 mm high density (M0) mineral wool.
•	2 EC motors, independently adjustable, external rotor type, integrating safety thermal cut-outs, with backward curved impellers directly driven by ball bearings; 2 speeds adjustable during the installation.
•	Air-to-air, counter cross-flow, aluminium made heat exchanger whose high performance, certified by Eurovent, exceeds 90% according to EN 308 standard.
•	Automatic pre-heater.
•	Circular branch connections with lip seals to grant the system air tightness.
•	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 security latch on removable panels.
•	Inner slanted tray to assure the proper condensate removal at product horizontally installed.
•	Advanced electronic control suite, including a control box enriched by a LCD display allowing:
o	To independently adjust the fan speeds,
o	To modulate the opening of the by-pass,
o	To set a weekly, holiday and public holiday timer,
o	To control the status of both filters,
o	To integrate the unit in a BMS (communication protocols supported are MODBUS, BACNET and WEB TCP-IP),
o	To set the unit operation mode in case of fire, to be allowed among 5 pre-defined fan control alternatives,
o	The machine diagnostic.
•	A podlockable local circuit breaker, mounted on front panel, allows to stop the unit in case of fault.
