Pressurization and Purge Safety Standards

Mitigate the risk of potential explosions with purge and pressurization

This protection method functions to limit the potential for an explosion by ensuring equipment is pressurized with a positive gas or purged with a diluting gas. There are three different types of pressurization that can be applied to a product:

  • Static
  • Leakage compensation
  • Continuous dilution
