Prevent Dust Collector Fires and ExplosionsFire Protection Solutions for Industrial Processes“If combustible dusts are collected, there is a fire and explosion hazard in the collector, regardless of bag construction.”FM Global Property Loss Prevention Data Sheet 7-73, Dust Collectors and Collection Systems(January 2012)...“Any time a combustible dust is processed or handled, a potential for deflagration exists.”...-NFPA 654 A.3.3.5 2013 EditionA Common HAzArdIs this a risk you are willing to take?Dust fires are common occurrences in industries that handle combustible dusts. A typical dust collector operating under normal circumstances is at risk for a fire or even an explosion. In fact, more than one-half of all industrial explosions where combustible dusts are handled develop within a dust collector. This is because the airborne dust particulate inside of a dust collector can present a recipe for an explosion to occur. The only element missing is an ignition source that is typically sparks generated by upstream processing machinery. Processes involving size reduction, drying, heating, cutting, welding, sanding, planing, grinding and polishing are particularly conducive to the generation of dangerous sparks.DELUGE ASSEMBLYAIR FLOWRETURNAIR TO BUILDINGBACKDRAFT DAMPERDUSTCOLLECTOREXTINGUISHING ASSEMBLYSMOKEDETECTORHIGH SPEEDABORT GATESECONDARYSPARKDETECTORSPRIMARYSPARKDETECTORSHEATDETECTORS FLAmEX SpArk dEtECtIon And SupprESSIon: tHE FIrSt LInE oF dEFEnSE Protection of downstream dust collectors and air filtration equipment is achieved by the elimination of the possible ignition source. Airborne sparks are both detected and extinguished as they are conveyed through the pneumatic duct before reaching the dust laden environment inside of a dust collector, bin or silo. Highly sensitive IR Spark Detectors are flush mounted on dust extraction piping to scan the material flow. Upon detection of a spark, the system reacts immediately to produce a curtain of water across the duct for effective suppression. The short spray duration uses a minimal amount of water so no downtime or clean up is required. Equipment shutdown and activation of alarms, deluge valves and Abort Gates can also be initiated upon detection.HIgH SpEEd Abort gAtES Rapid diversion of burning material, sparks, smoke and flammable gases from the pneumatic system is accomplished with the use of a high speed Abort Gate. It is typically installed on return air ducting between an outdoor dust collector and the building. The primary purpose of an Abort Gate is to protect the occupants of the plant from the dangerous products of a dust collector fire. It can also be used downstream of positive pressure fans to divert sparks or burning embers from the material flow to protect air filtration equipment.tHE SoLutIon“Ducts conveying dry material released by equipment having a high frequency of generated sparks shall be...(1) Equipped with a listed spark detection and extinguishing system installed downstream from the last material entry point and upstream of any collection equipment...”-NFPA 664 8.2.2.2.2 2012 EditionThe flexibility of the FLAMEX System allows us to create a protection design which will utilize the components necessary to best address the requirements of the specific application.CuStom dESIgnEd SYStEmS For EACH AppLICAtIonWhether you need protection for a small cabinet shop or a large industrial facility, a FLAMEX System can be designed to meet your needs.

Features include a removable lens and external LED. The standard version is suitable for use in operating temperatures between -22 and 176 degrees F. For higher operating temperatures, a fiber optic assembly (L-1) can be utilized. Optional air flushing attachment for lens is available for special applications.AutomAtIC EXtErnAL tESt LIgHtSpark Detectors can be tested automatically during operation with this special feature. The External Test Light emits an IR signal across the duct from a mounted detector. The detector must sense this simulated “spark” through the actual material flow thus providing a true test of detector response.WmX 5000 HEAt dEtECtorThis Heat Detector is an advanced thermal sensor that will alarm when a pre-set temperature is exceeded or when an abnormal rate of rise is detected. Set points can be reprogrammed in the field. Each unit has a recording feature which tracks temperature history and alarm activity. Hot pArtICLE dEtECtor FuX 3001-dLThe mid IR Detector can be used in certain applications where ambient light is present. It has the capability to detect hot particles that are not glowing. It is suitable for drop chutes, conveyors and certain duct work applications.bmX 1001 duCt SmokE dEtECtorThis sensor is used to detect smoke emanating from a dust collector fire. It uses air sampling tubes for monitoring in clean air ducts. Other models of smoke detectors are available including photoelectric and ionization.
