Cabinet
It is designed for horizontal air exhaust for CTHx type, for vertical air exhaust for CTVx type. The fan base is made of galvanized steel sheet, the brackets, grille and screws are also electroplated. The fan shroud and casing are made of Al sheet. The fan motor is mounted outside the air flow. The motor ventilation circuit is separate, using its own radial impeller. There is a ventilation joint around the perimeter of the canopy on the CTHx fan, on the CTVx type the motor ventilation is routed out of the side of the casing.
Iris wheel
The fan is radial with backward curved blades. It is made of galvanized steel sheet and is statically and dynamically balanced.
Clamps
It is accessible by removing the fan canopy, on single phase fans it also contains a start-up capacitor. The protection is IP55.
Motor
is asynchronous with shorted resistance armature, stator with cooling fins, black epoxy lacquer finish. CTH(V)B fan motors are 1-phase for 230 V, CTH(V)T are 3-phase for 230/400 V. The motors are equipped with a thermal fuse as standard. The windings are tropicalised with class F insulation and a permanent operating temperature of -40 to +200 ˚C. Grease-filled ball bearings for life. IP55 protection.
Speed control
is carried out by changing the voltage by electronic or transformer regulators or frequency converters. Motors marked 230/400 V cannot be switched to reduce speed by a Y/Δ switch and can only be operated in Y connection.
Mounting
The fan is to be mounted horizontally using accessories (with the motor axis vertical).
Rotation direction
is only possible in one direction, as indicated by the arrow on the fan housing. The opposite direction of rotation may cause motor overload, and the fan will also experience increased noise.
Noise
emitted by the fan is shown in the tables. The acoustic pressure is measured in the free acoustic field at a distance of 3 m at operating point 2 of the power characteristic (intake/exhaust).
