Explosion Protection Explosion occurs when 3 following elements are in place: 1. IGNITION SOURCE 2. FUEL 3. CONFINEMENT Dust explosions occur when fine particles dispersed in the air as a cloud react with oxygen in the presence of an ignition source, generating an exothermic chain reactions.
Causes of Explosion 1. Agricultural and food products: e.g.: Grain, Malt, Sugar, Flour, Sawdust etc. 2. Synthetic organic materials: e.g: Plastic, Pigments, Chemicals etc. 3. Metals: Aluminium, Magnesium. 4. Coal
Why use explosion venting? An explosion vent is designed to be the weakest part of the external structure. As the explosion vent experiences the pressure rise, it opens quickly allowing the rapidly expanding heated gases to be released to the outside. To protect people, facilities, equipment, buildings, etc. • To limit damage to the MIN (vented) area • To meet guideline authority recommendations/ legal regulations • To help guarantee the safety of silo installations •
Potential Industries • Pharmaceutical production • Chemical production • Energy/mining • Co-generation plants • Recycling centers • Automotive (air bag, plant lines) • Paper Process • Food production • Brewery Facilities (grain storage/processing) • Fossil Fuel Plants (coal dust) • Nuclear Power Stations
Applications • Silos & Vessels • Reverse jet Filters • Cyclones • Bucket elevators

What is a Burst Detection System? Instantaneous and fail safe method of Explosion Vent burst notification Why use one? Cannot rely on simply hearing the vent burst Can be wired to alarms or process control systems to activate an alarm Can be interfaced with process control systems so appropriate safety and follow-up methods can be taken which allows for : Emission control requirements o Minimises downtime / costs o Improved process safety o Enables automation and remote monitoring o
Vent-Tel (Panel Flo-Tel) Advanced explosion protection for a range of global applications. Designed to offer a practical solution for explosion vent burst detection, which can trigger a safe and rapid shut-down of the process. Non-invasive to the process Fail safe Zone 0 compatible and intrinsically safe Meets ATEX approval Can be supplied integral to the explosion vent or retro-fitted to Elfab’s new range of panels
Benefits of Magnetic Technology Non-invasive Only requires initial to process so Re-usable: One off electrical connection immune to process purchase and – Reduces negative conditions and fitting – impact of human removes potential Cost Reduction error secondary leak path Intrinsically safe Eliminates false (ATEX Zone 0) and Tested in situ - alarms Water resistant Reduced Downtime (IP66)
