CONSTRUCTIVE FEATURES
> CABINET WITH A REFINED DESIGN
- Front panel made of sheet steel, colour RAL9010. The front panel
incorporates an exclusive air flap which activates the convection heating
mode. The flap is opened and closed manually.
- Side panels manufactured from UV-stabilised ABS to maintain the colour
intact over time.
- Upper grill made of ABS (UV stabilised), adjustable louvers and flap.
The flap features a microswitch that automatically shuts down the unit
when the flap itself is closed. The side doors provide access to the
control panel and compartment housing the plumbing connections.
The doors may be secured by screws to prevent opening.
> HEAT EXCHANGERS
2X1 incorporates 2 heat exchangers for 2 distinct operating modes.
- 4-row convector exchanger made up of copper tubing and aluminium
fins secured to the tubing by mechanical expansion, complete with
brass manifolds and air vent valve. The wide spacing between fins
optimises the draught effect during natural convection.
- Fan coil exchanger, made up of copper tubing and high-efficiency
aluminium fins submitted to a hydrophilic surface treatment, secured
to the tubing by mechanical expansion. The exchanger comes
complete with air vent valves.
- The heat exchangers are normally connected in series, so that the 2x1
unit will be ready for installation in 2-pipe systems.
By removing the connecting pipe, 2x1 can be immediately converted
for installation in a 4-pipe system, where the convector exchanger will
be connected to the heating circuit and the fan coil exchanger to the
cooling circuit.
- The plumbing connections are normally provided on the left side but
may be switched over to the other side (180°) during unit installation.

> FAN ASSEMBLY
Including centrifugal fans with staggered airfoil-shaped blades,
manufactured from anti-static ABS.
The fans are housed in a low-noise ABS volute distinguished by a compact,
high-efficiency profile.
Four-speed electrical motor, mounted on vibration damping couplings,
directly connected to the fans, with permanently activated capacitor and
winding thermal protection .
> BEARING STRUCTURE
Bearing structure built from galvanised sheet steel of adequate thickness,
insulated by means of Class 1 self-extinguishing panels, supplied with an
installation kit (wall screws).
A support terminal board for electrical connections is located on the
bearing structure, on the opposite side of the plumbing connections.
> AIR FILTER
Honey-comb polypropylene washable air filter, mounted on a galvanised
sheet frame protected by a net, easily removable for maintenance
operations. The filter may be secured to the unit by means of screws.
> ACCESSORIES
- Speed switch
- Microprocessor panel for automatic control of the unit and the
connection to the ERGO control system
- Base support panels which conceal the pipes leading up from the floor
- Water flow regulating valves
- BIOXIGEN ionisation and purification system
