Explosion Venting

Many at risk industrial process components including dust collectors, process vessels, duct/piping networks and industrial structures can be protected with explosion venting.

This is what we’re about…

The strategy of explosion vents is to provide escape routes for flames and expanding gases, preventing the dangerous pressure build up in process equipment to minimize damage to equipment and protect personnel working in the area.

There are two primary means to vent a deflagration using explosion relief vents. These include explosion panels and flameless vents.

Explosion Panels


Explosion panels or vents are the most widely used method for mitigating or safely redirecting dust explosions. Explosion relief vents are an effective means for explosion protection when conditions include:

  • Equipment is located outdoors or near an outside wall when located indoors
  • Plenty of outside space (compliant with NFPA 68) is available for safe venting
  • Process material is not toxic

IEP Technologies| HOERBIGER Safety Solutions vents offer:

  • Vents have a two-year warranty
  • Industry best performance tolerances of +/- 0.25 psig and a max operating pressure ratio of 80%
  • 3 to 5 day ship time for SS vents
  • Broad range of sizes, configurations, and ratings available
  • Flat or domed designs
  • Clean-in-place designs available

Flameless Explosion Vents


Flameless vents are designed with an integral flame arrester that prevents the escape of flames and combustible dusts.  IEP Technologies | HOERBIGER Safety Solutions flameless venting has advantages that need to be considered:

  • Vent duct is not required – can be used in the building interior
  • Compact in size with wide range of sizes available
  • Up to 30% less length than standard flameless vents with more mass
  • Valve closes automatically after venting – repair or refurbishment not required
  • Suitable for multiple explosions
  • ATEX Approved
