Developed to withstand the most extreme conditions, the Helios smoke extraction roof fans in temperature classes F400 and F600 are invaluable lifesavers in case of fire.

Fire detection:
Smoke detector RMR
Control:
Smoke extraction controller EVS in conjunction with frequency inverter FU-CS
Safety:
Bearing condition diagnostics system LZD
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.
