Air purifiers for smoke and odour removal

It needs to be high enough to protect property and escape routes and to ensure that fixed smoke barriers will not adversely affect building usage while being kept as low as possible to minimize the cost of the smoke control system. Natural smoke ventilation uses the natural buoyancy of the hot gases to drive the smoke flow through the ventilators. Such systems often have a dual function and provide both smoke ventilation and day to day ventilation. By contrast powered smoke ventilation relies on mechanical extraction through fans. Our innovative smoke removal systems are great at removing dust, pollen, smoke and other particles from the air in commercial and industrial properties. As well as smoke and particle removal, our innovative systems can be used to recirculate fresh air and come either mounted to a wall or a unit.

Underground, garages are often located, and within the commercial space, shops and warehouses full of products which may fuel the fire. Other typical spaces for commercial centres are cinemas, gyms, server rooms and kitchens using open fire. Designing a smoke removal and ventilation system is a challenge not only with regard to safety but also ensuring proper air exchange to care for the comfort of the people inside.

Additionally, recommendations regarding the layout and activation of the shev devices can be made. Mechanical smoke exhaust systems are systems that use various types of mechanical equipment (fans, jets) to pump fire gases. Mechanical devices may be either part of a smoke exhaust system or individual smoke exhaust points. Mixed (hybrid) smoke exhaust systems are solutions that combine the functionality of smoke exhaust and smoke prevention systems. Overpressure smoke exhaust systems - the main purpose of this system is to prevent the smoke from filling the room. The basic principle of this system is to establish the direction of air flow (pressure gradient) - the highest pressure is maintained on escape routes.

The important role of a thermal expansion compensator in a smoke extraction system should be emphasised. It is obvious that sheet steel ducts demonstrate high expansion under high temperature. The fire resistance of ducts decreases, jumta logi increasing the risk of the duct losing its tightness and leaking smoke and heat.

At the moment smoke particles get into the path of the beam, the alarm is triggered. Computational fluid dynamics modelling undertaken by a fire engineering firm will help provide appropriate recommendations for a car park design, ensuring that all regulations are met whilst rationalising design. Enclosed car parks present a particular challenge in terms of ventilation, not only in the event of a fire but also in day-to-day exhaust fumes. Fire shut-off valves are installed at the ends of a general (comfort) ventilation system and at the points where the ventilation system passes through building partitions.

The current regulations require that a fire safety plan and fire scenarios for the premises subject to fire hazard are prepared. They are basis for further works consisting in designing and implementing the fire alarm systems or complete fire-fighting systems. If no such documents have been prepared for the respective structures, we may start from preparing them.. Our aim with car park ventilation is to provide the most cost-effective solution tailored to the type of car park, the layout of the car park and any additional fire legislation that may be in force over and above the basic code standards. When natural smoke ventilation cannot be implemented, impulse or induction fans can be used in addition to the natural openings to improve the cross-flow of air.

We also offer wall or ceiling surface mount machines, flush mount systems, and even portable solutions. As smoke and gases  are extracted, sufficient air needs to take their place. Otherwise the building will become depressurized and the smoke ventilation system will become ineffective.
