Example of use:
The smoke exhaust roof fans B VD ensure basic ventilation, for example, in a shopping mall. If a fire is registered by the Smoke detector RMR in a service unit, the smoke extraction controller EVS in combination with the Frequency inverter FU-CS will send a signal to the fans, which will switch to smoke extraction mode within fractions of a second. This ensures both quick and reliable smoke extraction and thus the safe evacuation of employees and visitors, as well as free access for the fire service. Another special feature of B VD series: The Helios Bearing condition diagnostic system LZD guarantees safe operation in case of emergency, even with long standstill periods.
