Fires and Explosions in the European dairy Industry were becoming an increasing problem. In the early 1990's two groups of people from industry, insurance providers and suppliers of protection equipment came together to analyse events and case studies, to find a new approach to solve the persistent problem.
The first now statistically confirmed finding was that the problem really was a fire hazard rather than a problem belonging to the area of explosion hazards. The analysis of a statistic database on 116 incidents in the milk powder processing industry showed that five of these incidents experienced an explosion, while another three had explosion like effects that could be traced to pressure effects of an explosion. The remaining incidents were fires only, with damages ranging from medium to total loss of the drying unit.
The handling of ignitable dust is an everyday hazard in process industries. More than 80 % of all industrial dusts are combustible. The early identification of these hazards and the appropriate application of protection measures not only save lives and equipment but also plant downtime. The ATEX Fire and Explosion Protection experts and its worldwide trained representatives take care of your safety.
The ATEX Passive Isolation Valve provides a fully passive system that does not require active dust management or low Pred values to function properly. Metal to Metal seal eliminates temperature considerations and failures.
The Quick Sliding Valve is triggered via specially designed detection and control systems. Immediately after an explosion is detected, a quick-acting solenoid valve is activated, and a piston is charged with an amount of pressurized air, stored in the Quick Sliding Valve. The Quick Sliding Valve closes almost without delay. The pressure reservoir is re-filled immediately and forcedly from the on-site air pressure network, enabling the immediate usability of the Quick Sliding Valve without any further effort.
