Smoke & Heat evacuation: Natural smoke & heat evacuation system from Mowin

In most cases of fire, the main causes of death, in addition to poisoning or burns, are suffocation due to gases and fumes that have no way of escaping. This risk is heightened because rescue teams cannot intervene quickly in smoke-filled buildings to evacuate people and extinguish the fire. Even without people involved, promptly evacuating fumes limits damage to goods and systems.

For 50 years, Comunello has developed technology to serve its customers. The new Mowin window drives range offers high technical content to ensure safety during fires. Initially experimental, providing smoke and heat control systems that comply with regulations has become necessary and often mandatory.

One effective system is the Natural Smoke and Heat Evacuation System (NSHEV). This system combines windows and actuators, which can withstand high temperatures up to 300 degrees. It creates a smoke-free layer at least 2.5 meters high during a fire, aiding evacuation and rescue operations. As smoke rises due to its higher temperature, evacuators placed at the top of wall compartments and roofs facilitate the escape of smoke and the entry of fresh air, directing smoke upwards. Control panels connected to the actuators ensure the evacuators open in emergencies, even without continuous electricity, thanks to backup batteries.

The European Directive EN 12101 is one of the strictest regulations, outlining performance evaluation methods and criteria for NSHEV. It mandates that evacuators and actuators be certified according to rigorous strength and reliability tests. These regulations are recognised internationally, underscoring their safety for certified actuator installations.

Comunello’s new MOWIN actuators, series L40 and L40 Slim, offer high performance validated through NSHEV qualification tests by notified bodies. These actuators are particularly suited for incorporation in evacuators and allow the creation of smoke and heat dissipation openings on existing window frames. They are reliable enough for natural daily ventilation. Tested within a window system, the actuators comply with EN 12101-2, functioning at temperatures up to 300°C and down to -5°C, ensuring operation in extreme conditions. They have also been tested for air pressure up to 1500 pascals, challenging their opening capacity and strength. The most complex test involves the actuators’ performance during a fire after up to 20,000 operating cycles in a short time. This stress test ensures the high standards and quality of the actuators, providing maximum safety when installed in a smoke and heat evacuation system.
