If you plan on installing an enclosure in a hazardous area, it is always paramount to install a ‘purge system’ that will withstand harsh surroundings and meet safety or regulatory compliance.
Purge systems are available in many different sizes and configurations, so it is wise to do the proper research and talk to a company or installer who has experience with this type of system. A poorly planned or poorly executed purge system can end up causing a disaster or explosion. But, first comes first, what is enclosure purging and how can it be used to protect computers and other essential peripherals?
How to find the best purge system for the application:
What is purging?
Purging is the process of supplying enclosures with compressed air or inert gas at the proper flow and pressure, in order to reduce the hazardous gas inside of the enclosure to a safe or more moderate level. Pressurization is the process of bringing compressed air within an enclosure to a pressure where there is no ingress of hazardous gases or combustible dust. Both purging and pressurization are required in a Class I or gas atmosphere. However, only pressurization is required in a Class II area or dust atmosphere.
