Industrial Dry Chemical Systems

Dry Chemical Fire Suppression Systems are extremely effective low cost automatic fire suppression systems for Class A, B and C fires. The extinguishing agent is stored under pressure using dry nitrogen gas. The system is designed to protect a wide variety of hazards involving flammable liquids, gasses, wood, paper and energized electrical equipment. The system can be used on many hazards found in any industry.

Dry chemical extinguishing agents work by forming a blanket to exclude oxygen, heat absorption, chemical inhibition or a combination of these depending on which agent is used. The system can be operated from automatic detection and/or manual actuation. Facilities are provided for shutting down electrical power and shutting down the flow of gas. The detection is by means of specifically rated mechanical fusible links or electric thermal detectors.

The system can be operated from automatic detection and/or manual actuation. Facilities are provided for shutting down electrical power and shutting down the flow of gas. The detection is by means of specifically rated mechanical fusible links or electric thermal detectors. The basic system consists of Dry Chemical Agent Cylinder(s), Distribution Piping and Nozzles, Control System and/or Releasing Device, Thermal or Fusible Link Detectors, and Accessories.

At each inspection all system components will be inspected and thoroughly tested for proper operation. Testing will include activation of all initiating devices ie: Smoke or Heat Detectors, Pull Stations and testing of all indicating devices as Horns, Strobes, Bells, etc. Auxiliary devices, such as Damper Closers, Fan Shutdowns, Door Closers, etc., will be tested. Detection-Abort-Discharge sequence will be tested for proper timing and operation. All system piping and nozzles shall be inspected. Agent quantity and pressure will be checked and appropriate tags filled out and affixed to cylinders and system.

Inspection Frequency: semi-annually
