Here’s how they work:

1. During a fire, the portion of the tube nearest the point where the most heat is detected ruptures, forming a spray nozzle.
2. The pressure decreases as the tubing releases fire suppression chemical from the cylinder through the spray nozzle (burst hole) to effectively suppress the fire.
3. A direct release system can be installed to protect multiple enclosures using a single cylinder by routing additional tubing to each enclosed space.

We recommend direct release systems for protection of electrical cabinets. For protection of vehicles or CNC machines, we recommend indirect release systems.
