Rosenberg AC-Radial fans in combination with a voltage-controllable external-rotor motor form a very compact, efficient and optimized fan unit. They impress with low installation depth and a simple installation. Fast start-up is ensured because of well-integrated components.

Those fans are designed and manufactured to be operated in vaporous explosive atmosphere. They are marked in accordance with the Atex directive 2014/34/EU: II 2G Ex h IIB+H2 T3 Gb X

Applications:
Air Handling Units / Roof Fans / Duct Fans

Motors:
The voltage controllable AC-motors are characterized by a compact, robust design and a good controlling behaviour. They are designed by standard with protection class IP44, thermal class F and ignition protection Ex eb or Ex ec.

Motor Protection:
The winding of the motors feature integrated triple Positive Temperature Coefficient (PTC) thermistor temperature sensors according to DIN 44082, which will have to be connected to a PTC thermistor tripping unit with protective mark Ex II (2)G as a motor protection. This specific thermal motor protection is capable of precisely identifying any abnormal operating condition and external influence and will then disconnect the motor from the mains via a contactor in any conceivable malfunction case. It is permissible to install commercially available motor circuit breakers only as additional safety devices, since they are not able to ensure complete motor protection under all conceivable operating conditions (e.g. operation with reduced-voltage). Electrical connection:
The fans are supplied as standard with a connection cable approx. 0.8 m long. Wiring diagrams are glued to the cable outlet side of the fan housing. An Ex connection box is available as an accessory.

Air volume control: Explosion proof external rotor motors.
The design of the motors allows for a stable modulation of the motor speed via a voltage reduction. Only transformer type open-/closed-loop control units may be used for this purpose. For correct assignment refer to the list of accessories. The permissible voltage modulation range of between 25 and 100 % of the nominal voltage meets the typical requirements of systems with a variable air flow. If the system is operated in the reduced-voltage range, the operating current may exceed the nominal current. The percentage current increase in comparison to the nominal current is listed under technical data as Delta I. Open-/closed-loop control units must be designed to handle the maximum operating current. Ex external rotor motors with type of protection „eb“ or „ec“ are not allowed to be used with frequency converters.
