Firetrace Direct Release Systems
How it works: In a direct release system, the suppressant will come through the hole in the tube directly. 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.
Common applications: Direct release systems are recommended for electrical panel and server rack protection.
Key benefits: The direct release system works well for protection of electrical hazards, because it does not rely on any metal components installed within an electrical enclosure. Metal components, like nozzles, can cause electrical arc faults, which actually increase your fire risk. Because direct release systems rely entirely on the tubing, a plastic material, fire risk is reduced.
