Fires and the associated heat and smoke development are still the biggest threat to people and buildings. Every year, many people die in fire disasters, fires also cause enormous property damage. However, the threat to people and buildings not only comes from fire and heat, but especially from smoke and the arising toxic fumes. For this reason, extracting the smoke quickly and reliably is highly important. This is where smoke and heat extraction systems as components of a preventative fire protection system play their most important role: evacuating fire gases, dangerous oxides and thermal energy into the atmosphere in case of a fire. In this way, smoke levels are kept low in escape and rescue routes, thereby permitting non-assisted and assisted rescue to take place.
