Explosion Isolation

Manufacturer: Kidde Brand- und Explosionsschutz GmbH

Applications:

• protection of equipment (silos, filters, cyclones, mixers, dryers, granulators, etc.) if flammable materials are present in explosive concentrations in process ducts,
• HRD cylinders are designed for the protection of any vessels, ducts and piping in which ST1-ST3 class dusts, gases and hybrid mixtures are present, across all industries

Manufacturer: Kidde Brand- und Explosionsschutz GmbH

Applications:

• protection of mills, filters, separators, driers, cyclic granulators, etc. Used in the process treatment of ST1 and ST2 class dusts, gases and hybrid mixtures
• for installation on ducts connected to equipment whose construction ensures resistance to the pressure of explosion and places where reduced pressure of explosion may cause damage to the enclosed parts of equipment
• suitable for installation in pipework carrying gases with low dust concentrations (e.g. after filters, before and after a batch drier)

Manufacturer: Kidde Brand- und Explosionsschutz GmbH

Applications:

• protection of mills, silos, filters, separators, driers, mixers, etc.; suitable for process treatment of flammable and explosive dusts (ST1 and ST2 class) and hybrid mixtures
• suitable for installation on ducts connected to equipment whose construction ensures resistance to the pressure of explosion and places where reduced pressure of explosion may cause damage
• the slide valve can be used in systems in the permanent presence of dust.

Manufacturer: Rembe GmbH

Applications:

• protection of filters, mixers, cyclones, mills, dryers and other process equipment as well as preventing the transfer of explosion effects to the rest of the plant area or equipment

Applications:

• grinding plants, wood processing, paint manufacturers
• chemical and pharmaceutical
• processes: drying, granulation, grinding, dust extraction

Manufacturer: Thorwesten Vent GmbH

Applications:

• protection against propagation of explosion from processing equipment (e.g. mills) to silos, filters or electrostatic precipitators by controlled venting of explosion effects to the atmosphere (explosion isolation) and/or
• protection against explosion propagation from silos, filters or electrostatic precipitators to the plant’s process equipment by controlled venting of explosion effects (explosion isolation)
