Description: MCR OSO THERM 75 smoke exhaust windows are automatic natural smoke exhaust vents. The main function of smoke exhaust windows is to remove smoke, fire vapours and thermal energy from confined spaces to the outside of a given building in order to contribute to protection of people and property by:
• Reducing the amount of smoke within escape routes;
• Facilitating fire-fighting and fire-extinguishing actions by ensuring only slight amounts of smoke on lower levels;
• Ensuring protection of a building structure and equipment;
• Limiting damage caused by smoke, hot fire gases and thermal decomposition products.
In particular cases, MCR OSO THERM 75 windows can be used to provide air supply in natural smoke exhaust systems. Additionally, they can be used for ventilation purposes.
MCR OSO THERM 75 windows come with the CE Certificate no. 1396-CPD-0032 conforming to the EN 12101-2:2003
