Engineered for continuous heavy-duty ventilation and emergency smoke clearance operating under extreme thermal loads up to 400°C/2 Hours.
In high-density European metropolitan areas like Berlin, emergency smoke and heat control systems (RWA - Rauch- und Wärmeabzugsanlagen) serve as critical life-safety barriers during structural fires. Under standard environmental conditions, smoke extraction fan drives operate as high-efficiency continuous ventilation units (S1 duty cycle). However, upon emergency signal trigger from building automation networks, these specialized electric motors must instantaneously transition into emergency duty cycle (S2 thermal run), sustaining continuous operation at elevated temperatures up to 400°C for 120 minutes (F400 category according to EN 12101-3).
As a premier European manufacturer and exporter of heavy-duty electromechanical drives with over 50 years of heritage (originating from O.M.E. Motori Elettrici s.r.l.), our specialized OMS Series Smoke Extraction Motors are custom-engineered to meet the strict regulatory guidelines of the Berlin Building Code (Muster-Leitungsanlagen-Richtlinie MLAR and Bauordnung Berlin BauO Bln).
Berlin's complex urban landscape—ranging from historic subterranean transit tunnels to state-of-the-art tech hubs—demands highly specified smoke extraction solutions.
Berlin’s extensive U-Bahn and S-Bahn tunnel networks demand high-capacity axial flow fan drives certified under EU Directive 2004/54/EC. OME’s OMS series motors feature reinforced cast iron end-shields and IP66 sealing to withstand piston shockwaves created by high-speed trains, while providing instant high-torque extraction during tunnel fire emergencies.
Commercial high-rises and multi-story underground parking structures in central Berlin require space-saving dual-speed motors. Operating at lower speeds for quiet daily HVAC ventilation (IE4 energy class) and ramping to maximum torque upon fire alarm trigger, our motors maintain toxic-free pressurized emergency stairwells.
The expanding hyperscale data centers around Berlin-Brandenburg demand continuous heavy-duty cooling combined with rapid smoke purging in gaseous fire-suppression zones. Our explosion-proof explosion-rated smoke extraction drives (Exd / Exe) eliminate ignition risk while guaranteeing rapid smoke evacuation.
"Information Gain Analysis: Unlike generic AC motors, certified DIN EN 12101-3 smoke extraction drives incorporate specialized rotor slot geometries and high-silicon electrical steel laminations that mitigate magnetic saturation during extreme thermal expansion. This ensures full rated torque even when ambient temperatures surpass 300°C."

Berlin’s stringent environmental targets (Berliner Klimaschutz- und Energiewende-Gesetz EWG Bln) combined with rigid fire safety regulations present dual challenges for mechanical specifiers.
Historically, emergency smoke extraction motors were oversized and operated inefficiently during daily ventilation cycles. OME solves this through IE4 Super Premium efficiency integration. By utilizing optimized stator core geometry and high-permeability magnetic steel, our OMS motors function as ultra-efficient continuous ventilation units during normal operational hours—dramatically reducing the carbon footprint of Berlin’s commercial developments—while retaining uncompromised emergency high-temperature survival capability.
Modern HVAC systems in Berlin routinely utilize Variable Frequency Drives (VFDs) for demand-controlled ventilation. Under VDE 0100-560 regulations, fire emergency ventilation circuits must feature guaranteed Fire Mode Override Circuits (FMO). When the emergency fire signal is latched, the VFD control must automatically lock out all motor self-protection alarms (over-temperature, stall, overload) and force the motor to run to destruction if necessary, prioritizing smoke purge to safeguard escape routes.

Direct answers to key technical, regulatory, and commercial inquiries when procuring smoke extraction motors for German construction projects.
Under German building regulations (Bauordnung Berlin and Muster-Ventilations-Richtlinie), smoke extraction motors must be tested and certified strictly according to DIN EN 12101-3. Depending on the building safety classification, motors must be rated as F200 (200°C / 120 min), F300 (300°C / 60 or 120 min), or F400 (400°C / 120 min). OME Motors provides fully documented, third-party laboratory certified drives complete with CE Declaration of Performance (DoP).
During standard daily HVAC operation (S1 duty), embedded PTC thermistors or PT100 sensors actively monitor winding temperatures to prevent motor burnouts. However, in an emergency fire scenario, standard thermal tripping violates life safety protocols. OME OMS motors feature high-temperature terminal blocks engineered with internal bypass connections. When switched to fire emergency mode by the central Building Management System (BMS), all protective tripping devices are bypassed, forcing the motor to operate continuously even under extreme thermal stress.
Yes. Our motors are built with specialized inverter-grade magnet wire and Class H VPI insulation systems that resist high voltage spikes (dV/dt) generated by modern VFDs. When operating with a VFD, German standards require the inclusion of an automatic bypass contactor or a VFD "Fire Mode Override" protocol that locks the VFD at 50Hz/60Hz full output during emergency fire conditions.
We provide all standard IEC mounting configurations, including B3 (foot mounted), B5 (flange mounted), B14, and specialized B30 / B35 pad-mounted designs tailored for direct insertion into cylindrical axial duct fans. Shaft extensions can be custom-machined from high-tensile stainless steel or specialized alloy steels to meet client impeller hub dimensions.
OME maintains a comprehensive stock of standard IEC frames (IE3/IE4) and core F300/F400 components across European distribution warehouses. Standard configurations can be dispatched to Berlin within a few working days, while highly customized OEM motors (custom shaft dimensions, special voltages, ATEX Exd certifications) are manufactured with optimized fast-track lead times.
