Pressure changes can be effectively managed by using vents

Fike is now offering Impulse Du-Flow pressure vents designed to relieve pressures that can occur with chemical gaseous-type fire extinguishing systems, effectively protecting the structure while enabling "superior" fire protection.

The clean agent gaseous fire suppression systems supplier recently expanded its offering with the addition of Impulse Technology to its ECARO-25®, HFC-227ea and DuPont™ FM-200® fire suppression products.

“When a gaseous clean agent system is discharged into a risk area, negative and then positive pressures are created,” said Kevin Kenny, Fike global product manager, fire suppression. “These pressure changes can be effectively managed by using vents.

“Clause 7.4.1 of EN 5004 part 1 mandates that ‘venting shall be provided to prevent excessive over- or under-pressurisation of the enclosure’. And as a matter of best practices, the Fire Industry Association (FIA) has recommended the use of pressure vents with these types of systems and has published a guidance document to support this requirement (Venting of Gaseous Fire Suppression Systems). Fike has embraced these recommendations and is proactively offering a quality vent product to complement our suppression systems.”

Available in three sizes, the Impulse Du-Flow vents’ performance has been fully tested and verified by the Building Research Establishment, says Fike, with actual, fully monitored gas discharge tests.

“We are excited to offer this quality venting system as part of our Impulse offering,” added Mr. Kenny. “The Fike Impulse Valve technology greatly improves the performance of clean agent fire suppression systems over mechanical valve systems by combining the reliability and efficiency of a rupture disc and the flexibility of electric actuation. And now the addition of the Impulse Du-Flow vents allows for the most effective and safe avenues for the protection of high value assets and equipment.”
