Fire protection systems must be used preferably jumta logi in all facilities where people are present and where the products of their labour are stored. Consideration should be given to the facilities listed in the decree of the minister of internal affairs and administration of 7 june 2010 on the fire protection of buildings as well as other structures and areas [5]. Mechanical smoke ventilation systems offer a number of unique advantages compared to their natural counterparts. As these systems utilise powered fans they can offer greater efficiency and controllability than natural systems, which rely on natural airflow to remove smoke from a corridor or lobby. Smoke extraction systems are used in particular in stairwells, assembly rooms and production or storage halls where smoke extraction is required.

You'll enjoy a smoke-free, healthier, fresher environment with little maintenance required. Just keep your magnetic cells clean in electronic smoke eaters or replace the filters in your media smoke eater on a regular basis. Concealed or ducted smoke eaters offer an unobtrusive way to remove smoke discreetly.

This has two independent power supplies (mains and battery) for guaranteed operation whatever the situation. Escape routes remain smoke-free and fire-fighters are able to intervene quickly, precisely where they are needed. Jet fans generate an air current that takes the smoke from the fire zone to the building extraction points. All sodeca’s extractor fans and fans for smoke evacuation comply with the highest standards and are certified by independent laboratories. They also can be independent systems or combined with a collective multi-zone ventilation system. Penetrations of fire partitions are qualified as components of a multi-zone ventilation system.

High temperature smoke extraction systems (300 ºc/2h and 400 ºc/2h) may be installed outside the fire zone or inside the zone itself. Sodeca has a wide range of certified extractor fans and fans for use in different environments such as buildings, shopping centres, car parks, large constructions with vast open spaces, industrial premises with a high risk of fire and industrial kitchens. Figure 3 shows the effects of not using a thermal expansion compensator at appropriate distances for smoke®system single-zone circular smoke ducts. Such a deformation of the duct may decrease its diameter and/or cause it to break or lose tightness, resulting in the malfunctioning of the smoke extraction ducts. The advantage of this system is the possibility of connecting ducts in two ways, I.E. Male-female coupling and by using steel flanges.

What's more, as one of the few manufacturers on the market, we offer thermal expansion compensators for smoke extraction systems in the male execution, made of our amt flexible duct connector. Smoke is able to cause loss of consciousness and cardiac standstill before a person may leave a house on fire. Jet ventilation system is the most suitable and safe ventilation solution for modern underground parkings. Arrangement of such ventilation requires no ductwork layout, thus the involved mounting expenses are reducted by 45 %. The energy losses caused by aerodynamic resistance in the air ducts are also reduced. The jet ventilation system design requires no complicated annual cleaning of the ductworks, thus reducing the maintenance costs by %.

Smoke extraction systems divert smoke from the building so that escape and rescue routes remain usable and people can get out into the open. Passive smoke management does not require mechanical systems  to support them. Instead, flexible fire and smoke curtains have been successfully used for fire and smoke protection for some time in elevators, but their application for atrium design is relatively new in the united states. A passive smoke management system, or smoke containment system, incorporates smoke and fire-rated curtains to compartmentalize fire and smoke keeping it out of the paths of egress. This must be proved on a case-by-case basis, with the use of mechanical systems being referred to as an ‘engineered’ rather than ‘code-compliant’ solution. Supply of fresh air to the lower area of the building optimises smoke and heat exhaust ventilation efficiency.
