NFPA 69: Standard on Explosion
Prevention Systems

The NFPA 69 standard covers the design, construction, operation, maintenance and testing of systems for the prevention of deflagration explosions by means of the following methods: (a) control of oxidant concentration; (b) control of combustible concentration; (c) explosion suppression; (d) deflagration pressure containment; (e) spark extinguishing systems.

All of FENWAL Protection Systems are design to meet or exceed the standard set by the National Fire Protection Association (NFPA).

FENWAL Protection Systems include but not limited to: Explosion Venting Systems, Explosion Isolation Systems and Explosion Suppression Systems. Quick detection of an ignition or explosion is a key to venting, suppression or isolation of explosive condition. To insure quick detection within various processes, FENWAL Protection Systems provide a wide range of detectors to meet most applications. These include: Ultraviolet (UV) Flame Detectors, UVIR Flame Detectors, IR-13 Infrared Flame and Spark Detectors, Static Explosion Pressure Detectors and MEX-3 Dynamic Explosion Detectors.

Explosion Suppression Systems

Explosion suppression systems from FENWAL Protection Systems are available for Spray Drying Systems, Fluid Bed Dryers/Coolers, Flash Dryers, Milling Systems, Cyclone Separators, Dust Collectors, and other process systems. FENWAL Protection Systems provides complete systems for protecting the process and personnel.

Deflagration Systems

Deflagration is a combustion that propagates through a gas or along the surface of an explosive at a rapid rate driven by the transfer of heat. FENWAL Protection Systems are designed to detect and contain explosions from spreading to interconnected equipment and other locations within the processing facility.
