Pressure relief stacks

for pressure relief of dust-explosions

By the special piping guidance in the pressure relief stack, the pressure of a dust explosion is relieved by a burst disc. Thus the propagation of dust explosions in pipes can be reduced considerably.

Pressure relief stacks - brief description

  • Material: steel, varnished or hot-dip galvanized, or made of stainless steel
  • Designed according to DIN 16020:2011 Appendix A and B, but without testing and without certificate of functionality
  • Accessories: Burst sensor, which detects the opening of the burst discPressure relief stack
