For use in buidings where automatic oipening of windows is required to prevent the buildup of smoke and harmfull gases.
During a fire considerable quantities of combustion products such as smoke and fire gases and heat energy are produced. The most important task of the RWA (smoke and heat extraction) system is to discharge the products of combustion from the building efficiently and quickly. Rooms and buildings without a RWA system fill up with toxic smoke gases within a very short time.
The risk for people trying to escape and the rescue services is significantly increased in buildings without a RWA system since the lack of smoke and heat extraction leads to an uncontrolled blazing fire, and the thick smoke makes active and passive rescue impossible.
