Convection units with double sandwich panelling in polyurethane foam of thickness 25 mm, designed for floor installation with vertical development. Air deliveries from 1.600 to 23.000 m³/h.
The shell is in extruded aluminium beams and nylon corner units.
Panels, «sandwich» type (thickness 25 mm) with double galvanised metal sheet wall, externally pre-varnished and high density (40 Kg/m³) polyurethane foam thermal insulation, are fixed onto the shell with screws secured by cotter pins.
The ventilation section is complete with forward bladed double in-take centrifugal ventilator, chosen for its low-noise feature.
The ventilator-motor group is supported by a frame in aluminium beams and insulated from the shell with rubber shock-absorbers and elastic joint on outlet. The electric motor, fixed on belt-stretcher rails, available in single or double polarity. Transmission is envisaged by means of trapezoidal belts and taper hub removable pulleys.
The Cu/Al exchange coils, measuring 60×30, are for hot and cool water functioning and drawer removable from casing.
The drainage tank, for the cooling coil version, remains inside the panelling and is made in suitably insulated galvanised metal sheeting.
