RWA Smoke & Ventilation

RWA / NSHEV & Eve­r­yday Ven­ti­la­tion Sys­tems

We all know that in eve­r­yday life fresh air is important in order to be able to con­cent­rate and remain fatigue-free when working and for general well-being. In the event of a fire, however, fast detec­tion and removal of smoke is essen­tial for survival. Find out how controlled ven­ti­la­tion can be imple­mented and how you can ensure that fresh air is supplied and smoke extracted where it counts.

Smoke and heat exhaust ven­ti­la­tion sys­tems (RWA)

Smoke and heat exhaust ven­ti­la­tion sys­tems are essen­tial for fire pro­tec­tion. In app­li­ca­tions where the reliable per­formance of a smoke exhaust installa­tion in the event of a fire is crucial and when fumes need to be removed quickly, smoke and heat exhaust ven­ti­la­tion sys­tems (RWA) from Gretsch­-Unitas ensure the reliable and automatic ope­ning of smoke extrac­tion apertures. They minimise the deve­lop­ment of smoke in escape and rescue routes, thus pro­tec­ting people from poi­so­ning due to smoke inha­la­tion and pro­perty from damage. In eve­r­yday ope­ra­tion, they ensure a controlled supply of fresh air.

Natural smoke and heat exhaust ven­ti­la­tion devices (NSHEV) in accor­dance with EN 12101-2

According to EN 12101-2, sys­tems are only approved for use on vertical facades if they have been tested and approved with all their compon­ents as a whole. Here you will find GU NSHEV system solu­tions with cer­ti­fied compon­ents for timber and aluminium pro­files with Euro-groove from all leading pro­file system suppliers and for all cust­omary window types.

24 V drives

RWA drives and RWA ope­ning sys­tems from GU gua­rantee fast and reliable smoke extrac­tion in the event of a fire and pro­vide natural eve­r­yday room ven­ti­la­tion. The GU range comprises chain drives, spindle drives, locking drives and combined ope­ning sys­tems.

Control cen­tres 24 V

RWA cen­tral control units from GU control the extrac­tion of smoke gases in the event of a fire as well as eve­r­yday room ven­ti­la­tion. They con­sist of compact or exten­dable modules with backup batte­ries gua­ran­te­eing at least 72 hours of ope­ra­tion during a power failure.

Ven­ti­la­tion sys­tems

GU offer cust­omised and comfor­table solu­tions for eve­r­yday room ven­ti­la­tion. Whe­ther for Tilt-Only or Top-Hung sashes, or pit­ched, tri­angular, round and seg­mental arch win­dows ope­ning inward or outward – GU ven­ti­la­tion sys­tems leave not­hing to be desired.

ELTRAL / 230 V AC

Chain drives from GU pro­vide a modern solu­tion for room ven­ti­la­tion. Thanks to their flat and compact design, they ide­ally harmo­nise with win­dows of any type and architectural style. Offe­ring a great number of face-fixed or concealed moun­ting vari­ants, they can be used on inward or outward-ope­ning Tilt-Only, Top-Hung, Turn-Only, Par­allel-Offset, and Pro­je­c­ting Top-Hung win­dows as well as on Horizontal or Vertical Pivot win­dows and sky­lights.
