Gaseous Fire Suppression Systems
Demand for Apreco fire suppression vents is increasing with the recognised need for over and under pressure venting associated with Inert and Synthetic Gaseous Fire Suppression Systems.
Buildings are most commonly designed to withstand internal pressures of between 250 to 500Pa, though this can vary depending on the type of construction. The use of correctly sized and functioning pressure relief vents will protect such building structures from damage.
Apreco FSV & SGV pressure relief vents are of 'counter-weighted' design to prevent the risks of over and under pressurisation resulting from the use of gas fire suppression systems. The Apreco range of pressure relief vents have been successfully tested to EN1363-1 criteria to provide a 4-hour fire resistance rating.
Specifically developed for these applications, the range can be used alongside a wide range of gas fire suppression systems to prevent structural damage and risk to personnel.
The vents can provide up to 85% free venting area (F.V.A.), thus reducing the space taken up by the units and the cost of installation.
Maximum room pressure is controlled by the vents opening to allow air to escape, then closing when discharge is complete. This maintains the dilution of the air, so preventing re-ignition.
The range of options include low loss external weather louvres, internal egg crate cover grilles.
