General Description

DKL TYPE-S AUTOMATIC AEROSOL FIRE EXTINGUISHING UNIT is a new class of fixed fire extinguishing system using solid propellant aerosol technology. Unlike conventional fire extinguishing systems, it is stored as a stable solid chemical compound which when activated generates a fire-fighting aerosol. The extinguishing medium however is not stored in a pressurised cylinder. The aerosol is a mixture of gases and micron-sized solids, possessing gas-like distribution properties and long holding times, totally floods the protected enclosure and rapidly extingsuies any fire present.

DKL fire suppression systems, can be characterized as requiring no piping, zero storage pressure, solid-state technology, environmentally friendly, non-conductive & non-corrosive, and has significant space & weight advantages in comparision with gaseous systems.
