Explosion Suppression

Explosion damping consists in identifying the initial explosion phase and injecting a damping agent inside the protected device. Thereby, the explosion is damped immediately upon ignition of explosive atmosphere, which prevents excessive pressure and fire from formation inside the apparatus. The time counted from detection of an explosion to explosion damping is counted thousandth part of a second (from 0.0075 to 0.0300 s).

The explosion damping system is the most universal method of protection of machines and plants against explosion effects. It is the only one that completely eliminates explosion effects and prevents fire.

Components of the explosion damping system

HRD-E type extinguishing cylinders

Application: explosion protection of equipment units (including silos, filters, cyclones, mixers, drying plants, pelleting machines, etc.) in presence of flammables at explosive concentrations levels. The HRD cylinders provide explosion protection for processing equipment units, vessels, and ductwork which contain class ST1 to ST3 particulate matter, gases and/or hybrid mixtures in all industrial sectors.
