CZBA Ltd. offers ATEX-conform filter systems for the filtration of combustible gases and dust as well as for their employment in hazardous environments (in a potentially explosive atmosphere). Our filter systems are designed according to the European guideline 94/9/EC for the putting into circulation of explosion-proof equipment.
Following careful analysis of the technical boundary conditions, a structural explosion protection is determined in the case of filter systems with a low flammable concentration. Taking account of the explosion characteristics defined by the customer and the zoning of the plant, the measures necessary to protect against explosion and release of pressure are determined. The bursting discs are matched to the size of the plant. In case of emergency they ensure a rapid and effective release of pressure, which prevents secondary damage. To attain the maximum degree of safety for filter systems, CZBA also integrates many additional safety mechanisms such as e.g. filter materials which discharge static charges, metallically earthed components and thermal overload protection for motors. Explosion isolation in the raw gas and clean gas pipeline as well in the discharge equipment are standard features in CZBA filter systems with structural explosion protection.
Application:
Explosions can occur wherever combustible gases, vapours, liquids or dust arise, are stored or transported. Under certain preconditions an explosive mixture can occur in connection with air. Given an ignition source, an explosion can take place.
Typically hazardous applications involve the filtration of organic or metallic dust in the chemical or metal-working industry. Yet firms that process or transport dust-creating bulk goods such as grain, feedstuffs or other organic products.
Processes which may give rise to the risk of explosion are:
- agglomeration, drying and coating
- cutting, welding, grinding, buffing, sanding a.o.
- bulk goods handlin
