From our very beginnings in 1946, Koorsen Fire & Security has been helping businesses protect unattended fuel outlets, paint booths, transformers, switchgear rooms, and wood finishing operations with dry chemical fire suppression systems. These systems release a dry chemical powder to suppress a fire in a designated space. From design to installation to continued inspections and service, our dry chemical suppression experts will ensure your hazard is protected.


Dry chemical fire suppression systems are typically required to be inspected and tested every 6-months, depending on the type of system. This includes inspecting the initiating devices, fusible links, release devices, piping, nozzles, cylinders and signal. Our team of experts understand the importance of a properly functioning suppression system and will work hard to ensure they will be ready if needed.


Continuous service and maintenance are important factors in ensuring that your dry chemical fire suppression system is operational. From 6-year maintenance to 12-year hydrostatic test to replacing hose assemblies and nozzles, our technicians will make sure that all deficiencies found during regular inspections and testing are addressed immediately. In the case of emergencies, we are available 24/7 to fix the problem as soon as possible.

A dry chemical fire suppression system is activated either manually via a pull station or automatically using fusible links. A dry chemical powder is released into the protected space. Sodium bicarbonate and mono-ammonium phosphate are the most common powders used in a dry chem suppression system.

They are typically required to be inspected every 6-months by a certified clean agent technician. They require maintenance every 6-years and a 12-year hydrostatic test depending on manufacturer.
