PWNi

The range of PWNi duct units is designed for air conditioning systems in interiors requiring the installation of particularly versatile, low-noise, medium-head units in false-ceilings.

Thanks to the particular conception underlying its construction, the basic model can be expanded with a series of modular accessories so as to enable the application of PWNi units in commercial interiors, hotel bedrooms, meeting rooms, etc.

Bearing structure built from galvanised steel sheet, insulated with condensation proof, self-extinguishing material in Class 1. Large drip tray for collecting condensate from the heat exchanger coil and regulating valves. Double suction aluminium centrifugal fans, with statically and dynamically balanced forward-curving blades, directly coupled to the electric motor. 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). High efficiency, 3, 4 or 6 row heat exchanger with copper piping and aluminium fins. Air filter made of acrylic fibre, filtration class EU2, applied on the air intake; may be pulled out from below. Control panels available as accessory.
