The Manchester, UK, office of explosion protection specialist BS&B Safety Systems has announced the introduction of System V, which is said to feature the company’s most advanced, ATEX-certified, chemical suppression and isolation technology to date. Its rapid response chemical suppression prevents flame propagation and isolates interconnecting process equipment, quickly detecting the smallest indication of an incipient explosion in process equipment and delivering a dry chemical extinguishing agent via a Cannon* to prevent a developing internal deflagration.
 

It is designed for installation in facilities that generate or handle combustible dusts posing potential safety risks to personnel, equipment and property.  These industries include: pharmaceutical, chemical, grain, feeds and food. The suppression and isolation system can be activated by various means, whether triggered by pressure, optical or vent sensors. When the Cannon deploys, it releases sodium bicarbonate to fully suppress a dust explosion.  Cannon deployment is prompted by a low voltage electrical signal generated from sensors in a smart controller unit which subsequently activates the Cannon. The actuators release pressurised nitrogen gas towards the sodium bicarbonate canister which discharges its contents at high velocity in milliseconds. The Cannons’ critical circuits are continuously monitored and any events are reported at a controller’s touch screen. There are failsafe features, such as dual electrical and mechanical lockout mechanisms which prevent accidental discharge of a Cannon into the protected equipment. www.bsbipd.com 

 

 

System V’s modular Cannon comprises five key components: Cannon body, extinguishing agent canister, actuation mechanism, pressurised nitrogen tank and Cannon electrical enclosure
