Smoke and heat exhaust ventilation systems Smoke and heat exhaust ventilation systems from Gretsch-Unitas. Fires and the associated flames and smoke still pose the greatest threat to people and buildings. For this reason, it is extremely important that the smoke be extracted quickly and reliably. The Gretsch-Unitas Group offers a wide range of coordinated system components – from electric motor drives to RWA central control units plus an extensive range of accessories. The following pages contain a summarised overview of the additional information regarding projects, planning, installation...

RWA / NSHEV І General information PhotoAlto Agency RF Collections / Getty Images Smoke and heat exhaust ventilation systems as an essential part of preventative fire protection What is meant by preventative and defensive fire protection? In order to protect the life and health of humans and animals, advance precautions should be taken to eliminate or minimise the generation and spread of fire and smoke. According to the definition, this involves measures for preventing the outbreak and spread of fire as well as ensuring that the escape routes are safe. This applies to all measures introduced by...

Preventative fire protection does not fully guarantee the prevention of fires in buildings. However, it is possible to achieve protection targets through the use of smoke and heat exhaust ventilation systems. Protection targets of a smoke and heat exhaust ventilation system Protection targets of a smoke and heat exhaust ventilation system Protection of personnel (= unassisted rescue)  Securing escape and rescue routes by smoke extraction Fire fighting (= assisted rescue)  Low-smoke extinguishing routes  Clear visibility for people escaping  Rapid and targeted extinguishing by the fire...

RWA / NSHEV І General information RWA, NRA and NSHEV – definition of terms The umbrella term RWA stands for "Rauchund Wärmeabzugsanlage" (smoke and heat extraction system). This comprises ■ a natural smoke extraction system (NRA) The Gretsch-Unitas Group offers the latest electromotor-driven RWA technology relating to natural smoke extraction (NRA) for all areas of application: from stairwell smoke extraction to complex RWA systems for large projects. ■ a mechanical smoke extraction system (MRA) ■ a smoke protection pressure system (RDA) or ■ a lift shaft smoke extraction system The term NRA...

Smoke extraction, smoke ventilation – definition of terms Smoke extraction Smoke ventilation Smoke extraction refers to the extraction of smoke in the event of a fire (heat extraction), in order to create a low-smoke layer near the ground and thus enable the safe use of escape and rescue routes. Smoke extraction systems in stairwells are referred to as smoke ventilation. Their purpose is to extract smoke by way of cold smoke extraction. The products used here are safety-relevant building products that are regulated by EN 12101-2 in Building Rules List B, part 1. In these cases, it is...

RWA / NSHEV І General information Functional principle of an RWA system RWA systems essentially consist of the system components seen in the system design below. They cover two large areas of responsibility: emergency situations and everyday ventilation. RWA systems from the Gretsch-Unitas Group are used for the everyday ventilation of rooms as well as smoke extraction in the event of a fire. Here, the dissipation of smoke and heat is controlled by the electrical controller (RWA central control unit). Windows, smoke flaps and light domes are opened or closed using electric drives. The...
