SHEVS stands for smoke and heat extraction, which is an essential element of fire prevention. A fire produces heat, toxic smoke and hot combustion gases. SHEV systems channel these away from the inside of a building to the outside.
How do SHEV systems work?
Smoke and heat control systems are available in various designs. Mechanical and natural systems are the two main types. The systems we offer are natural smoke extraction systems (NRA). With this type of system, the smoke gases are extracted via roof or wall openings, for example by integrating them into the skylight dome or continuous rooflight systems. It must be possible to trigger the NRA both manually and automatically. To ensure smooth operation, the systems must be serviced regularly.
Are RWAs required by law?
Smoke and heat extraction systems (SHEVS) are prescribed by the building regulations of the federal states, fire protection concepts, insurance requirements and building permits.
SHEV systems are required in buildings that require a low-smoke layer in the event of a fire, such as industrial buildings with production halls or warehouses. They ensure that escape and rescue routes can be used for longer and that people can get outside. In addition, SHEV systems facilitate extinguishing and rescue work.
There are several factors to consider when selecting a SHEV system, such as the size of the roof, the windows and the façade, as well as the room height and the required low-smoke layers. Taking all these factors into account, Fritz Manke GmbH will help you find the right SHEV system for your requirements. With our expertise in smoke extraction systems, we ensure that the system you choose fulfils all requirements and offers optimum protection.
