Sustavi natlačivanja stubišta i evakuacijskih zona

Spašavanje ljudskih života i omogućavanje sigurne vatrogasne intervencije nema alternative

U trenutku požara obrambeni sustavi imaju za zadaću osigurati čiste evakuacijske zone za kretanje stanara i osoblja spasilačkih službi, jer dimni plinovi predstavljaju najveću životnu ugrozu. Stoga, elektronski upravljani nadtlačni sustavi donose novu dimenziju zaštite od požara. Jednostavnim prekidačem, vatrogasne službe mogu prebaciti ventilatore dovodnog zraka na maksimalnu snagu, ograničavajući potrebu za korištenjem mobilnih ventilatora ili ih čak čine nepotrebnim. To znači da su napredni elektronski sustavi nadtlaka sposobni osigurati evakuacijska područja za samospašavanje ljudi, a također pružaju i dodatnu zaštitu od dimnih plinova za vatrogasno osoblje, čak i pri visokim temperaturama uslijed požara. Omogućuju jasnu vidljivost i općenito brži dolazak do izvora vatre prilikom intervencije.

Systemair je vodeća tvrtka kada je u pitanju kombiniranje napredne EC tehnologije i tehnologije upravljanja frekvencijskim regulatorima. Zrakotjesne zgrade, sa vrlo malom propusnosti u svojim konstrukcijama postavljaju veće zahtjeve za planiranje i provedbu koncepata za odvod dima i topline. Pri dizajniranju nadtlačnog sustava značajnu ulogu imaju ventilatori za odvod dima koje je potrebno ugraditi u posebne trase (šahtove.) Objedinjavanje oba sustava - sustava za odvod dima i sustava nadtlaka u funkcionalni i cjeloviti koncept, najnoviji je razvojni smjer Systemaira.

Benefits of electronic overpressure systems

  • Faster self rescue: Fire escape stairways are recommended even if other arrangements are permitted for escape and rescue routes. People evacuation is faster through smoke-free stairways or stairways with less smoke – the panic risk can be reduced.
  • Faster rescue by others: On electronic overpressure systems, the air supply of the fans can be switched to the maximum air volume by a fire fighter's switch. This enables pushing back and leading smoke away, even at high fire temperatures. The pressure in the stairway exceeds the standards limitation, and a time-consuming installation of mobile fans, allowing a clear view, in many cases is unnecessary.
  • More flexibility during fire-fighting operations: Mobile fans placed in the building entry can become a „tripping hazard“ for emergency task forces. With the Systemair Pressure Differential System those fans are not needed.
  • Higher security for emergency task forces: High air velocities combined with electronically controlled ventilation reduces the concentration of flammable gases and hot air in the zone on fire. This reduces the risk of backdrafts and delays flashover.
  • Higher building protection: With the possibility of overriding the set pressure with the electronic overpressure system a faster access for the firefighters is enabled. This reduces fire damages which can be honoured by the assurance in certain cases.
  • Reliability: Electronic overpressure systems are not affected by wind loads, snow coverings or pressure changes due to cold or warm supply air.
  • Reduction of construction costs: Openings for air outlets are not required. Control dampers and additional weather protection equipment are usually not necessary.
  • Reduction of operating costs: No complex adjusting or cleaning of mechanical control dampers.
  • Steady precision during life cycle: Electronic overpressure systems automatically compensate potential leakages due to normal wear and tear of the building.
  • Architectural freedom: Huge air terminal devices or high roof fans are not required.
