Cabinet
is designed for horizontal (CRHx) or vertical (CRVx) air exhaust. 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 metal. The fan motor is mounted in the air stream. The fan is protected by a grille against the ingress of foreign bodies.
Iris wheel
The fan is radial with backward curved blades. It is made of aluminium sheet and is statically and dynamically balanced.
Square box
with a revision switch, it is located on the base (CRHx) or housing (CRVx) of the fan. For single-phase fans, the terminal block also contains a start-up capacitor. The protection rating is IP55.
Motor
It is asynchronous with shorted resistance armature, with external rotor. The motors are equipped with a thermal fuse as standard. CRH(V)B fan motors are 1-phase for 230 V, CRH(V)T are 3-phase for 230/400 V. The windings are tropicalised with class F insulation. Protection rating IP54.
Speed control
is carried out by changing the voltage by electronic or transformer regulators (except CRHT/4-450 and CRVT/4-450), three-phase types also by frequency converters.
Direction of rotation
is only possible in one direction, in the sense of the arrow on the fan housing. The opposite direction of rotation can cause motor overload, and the fan will also experience increased noise.
Mounting
The fan is mounted horizontally using the accessories (with the motor axis vertical).
Noise
emitted by the fan is given in the tables.
