CHARACTERISTICS

VERSION
UNDER Downflow air supply
OVER Upflow air supply

Unit for installing inside or outside the room to be air-conditioned.
Maximum resistance to rust thanks to galvanised sheet metal structures and panels with powder-coated paint finish.
The panels are lined with sound-insulating material to limit noise levels.
The reliability and functionality of the compressor and all the other parts are guaranteed by partners who are world leaders in their sector.
NEW EC INVERTER fans with electronic commutation in order to maximize the energy saving and reducing the noise emissions.
The fan section is contained within the machine and includes: centrifugal fans with backward curved blades with wing profile, single suction and without scroll housings (Plug-fans), directly coupled to external rotor EC electric motor brushless type with integrated electronic commutated system and continuous variation of the rotation speed.
Standard G4 filtering section, M5-F9 optional, to CEN-EN 779 with average degree of separation 90.1% ASHRAE.
The filter is self-extinguishing.
The microprocessor controls the compressor activation times with FIFO logic, thereby regulating the cooling capacity; it also controls the operating alarms with the possibility of interfacing to supervisor and remote-servicing systems.
Refrigerant circuit consisting of an electronic expansion valve that allows high performance and system efficiency thanks to a timely and accurate response to changes in temperature and pressure; sight glass; filter dryer on liquid line; pressure transducers with indication, control and protection functions, on low and high refrigerant pressure; high pressure safety switch with manual reset; liquid receiver with accessories.
Switchboard to IEC 204-1/EN60204-1
