Skip to contentTube-based suppression that deals with the fire inside the cabinet, in the first seconds, with no power and no wiring.

Firetrace protects the inside of electrical enclosures, where most industrial fires actually start and where nothing in the room can see them until the cabinet has been breached.
A pressurised polymer detection tube is routed past the components most likely to fail. At the point of highest heat the tube bursts, the pressure drop opens the cylinder and agent is released directly at the seat of the fire. Intech surveys the enclosure, installs and maintains it.
Direct and indirect arrangements suit different enclosure sizes.

Pressurised detection tubing is installed through the enclosure, past the risk.
Rising temperature at any point weakens the tube wall there.
The tube ruptures at the hot spot and the pressure drop opens the cylinder.
Agent discharges inside the cabinet before the fire can leave it.
Usually the cheapest meaningful risk reduction on an industrial site, because it protects the one place nothing else is watching.

Once the tubing detects the fire, it ruptures, resulting in a drop of pressure causing the indirect valve to activate. The valve diverts flow from the detection tube to the larger outlet ports. When the fire suppression system kicks in, a suppressing agent is discharged from the cylinder through the diffuser nozzles, flooding the area while effectively suppressing the fire quickly and thoroughly. An indirect release system is typically used in larger areas that require a high volume of extinguishing agents to suppress the fire effectively.

During a fire, the portion of the tube nearest the point where the most heat is detected ruptures, forming a spray nozzle. the pressure decreases as the tubing releases fire suppression chemical from the cylinder through the spray nozzle (burst hole) to effectively suppress the fire. A direct release system can be installed to protect multiple enclosures using a single cylinder by routing additional tubing to each enclosed space. 1101, 11th floor Technocity IT Premises co-op Society, Sector X-5/3, TTC Industrial Area, Mahape Navi Mumbai 400710 All Rights Reserved By Intech Fire & Security Pvt Ltd.
