Technical specifications

FLAT by Galletti represents a new generation of fan coil units and has been engineered to offer performance and design features placing it at the top of its category. FLAT means innovation also in terms of engineering: it combines a guarantee of excellent low-noise performance with the advantage of an exclusive design that fits well with both residential and commercial settings.

Stylishly designed cabinet (colour RAL9010), front panel made of sheet steel, side panels and an upper grille with covers on either side manufactured from UV-stabilised ABS. The upper grille consists of a flap and adjustable louvers. The flap features a microswitch that automatically shuts down the unit when the flap itself is closed. High efficiency heat exchanger made with copper piping and aluminium fins. Double suction centrifugal fans manufactured from anti-static ABS, with blades having an airfoil section and offset modules. Electric motor with BLDC electronic switching system (brushless), mounted on vibration damping couplings. The unit is equipped with an inverter board to control the motor, that makes it possible to precisely set the maximum rotation speed of the motor (control signal 0-10 V). Washable air filter, easily removable for maintenance operations. Control panels available as accessory.

2x1 with BLDC motor hybrid version available
