We Wrote America’s Foremost Guide on Purging!

Our CEO formed the first company that manufactured stand-alone purging systems in America in 1985. He was also a voting member of an NFPA 496 Subcommittee for 15 years, and contributed significant content to improve that Standard.

He also wrote America’s most definitive guide for purging technology, and carefully trained our team to understand and share his knowledge.

The guide explained all purging concepts and requirements in layman terms, and featured many insightful illustrations.

That guide was so highly revered, its images and text are still widely copied and used to this day to best explain the safe application of purging!

So how does that benefit you? The answer is simple. Who’s best equipped to help you understand NFPA 496 code requirements and the principals behind them?

Without doubt, it’s the people who helped to write them! Get the best advice and guidance from the original founders of this technology now, by giving us a call or clicking our chat button.
