DIRECT RELEASE SYSTEMS:-
The Direct Release System utilizes the Detection Tubing as both the fire detection device and the fire suppressant delivery system. The portion of the tube nearest the hottest point of the fire ruptures, forming an effective discharge “nozzle”. The pressure drop in the tube releases the entire contents of the cylinder through this nozzle.
INDIRECT RELEASE SYSTEMS:-
With the Indirect Release System, the Detection Tubing is used only as a detection device. The fire suppression agent is delivered via copper tubing, stainless steel tubing or braided hose. Once the tube “bursts” the suppressant is discharged. An indirect fire suppression system is typically used in larger areas that requires a high volume of extinguishing agent to suppress the fire Effectively
Both Direct and Indirect systems are available in low- and high-pressure functionality for areas of any size. A fire suppression specialist will determine which system is right for your application.
