Outer casing
Made of strong synthetic lateral corners and from galvanized and prepainted front steel panel.
The plastic top grid has fixed louvres and is reversible in order to distribute the air in two different directions.
Standard colours:
• Lateral corners and top grid: Pantone Cool Grey 1C (light grey)
• Frontal panel: RAL 9003 (white)
• Other colours on request.
Inner casing
Made from 1 mm galvanized steel insulated with 3 mm polyolefin (PO)
foam (class M1).
Filter
Polypropylene cellular fabric regenerating filter.
The filter frame of galvanized steel is inserted into special
plastic sliding guides fastened to the internal structure for
easy insertion and removal of the filter.
Filter presence is highlighted by a plastic front cover featuring
the same colour as the top grid.
Fan assembly
The fans have aluminium or plastic blades directly keyed on the motor with double aspiration and they are dynamically
and statically balanced during manufacture in order to have an extremely quiet operation.
Electronic motor
Three phase permanent magnet brushless electronic motor that is controlled with reconstructed current according to
a BLAC sinusoidal wave. The inverter board that controls the motor operation is powered by 230 Volt, single-phase and,
with a switching system, it generates a three-phase frequency modulated, wave form power supply. The electric power
supply required for the machine is therefore single-phase with voltage of 230-240V and frequency of 50
-
60Hz.
Coil
It is manufactured from drawn copper tube and the aluminium fins are mechanically bonded onto the tube by an
expansion process. The coil has two 1/2 inch BSP internal connections and 1/8 inch BSP air vent and drain.
The coil is not suitable for use in corrosive atmosphere or in environments where aluminium may be subject to
corrosion.
The connections are on the left side facing the unit. On request we can deliver the unit with the connections
on the right end side. This operation can also be easily carried out on site during installation.
