ShredderGuard

Frequent fires in shredders often result in production downtime and loss of revenue. A fire in a shredder can spread very quickly. Therefore, Firefly has developed Firefly ShredderGuard, a Quick Suppression System that can withstand the tough conditions in and around a shredder. The main focus of the Firefly ShredderGuard™ solution is to detect and extinguish a fire in a shredder as quickly as possible. This is why a Firefly safety system always consists of three main integrated functionalities: detection, extinguishing and control. By integrating different techniques (flame detection, True IR-detection, full-cone water spray extinguishing and water mist suppression) into one solution, Firefly provides optimal safety for the protection of shredders.

Technical Description – ShredderGuard

Description 

The shredding process is highly exposed to fire incidentsForeign unwanted objects such as stones or metal pieces in combination with dust often start fires in waste shredderAlso paper shredders are commonly exposed to fires due to dust generated by the shredding process 

False alarms due to light is the most common problem with conventional spark detection systems using photocell detectors. 

In a shredding line there are many areas where light can enter 

  • Openings into the process 
  • Doors or hatches

False detection will lead to unnecessary water injection and costly production stop
