[Case Study] NORTH TEXAS, Sentry™ Emergency Gas Scrubber (EGS)

Written by Randie Shingleton | Mar 4, 2026 3:29:23 PM

A very large North Texas Municipal Water District 
(NTMWD) has three Emergency Gas Dry Scrubbers (EGS300) on site in the event of a chlorine leak. On Wednesday, 
June 15th, one of the scrubbers had a significant chlorine 
leak during the middle of the night. By the time their 
main chlorine alarm system alerted staff to the leak, 
PureAir’s EGS-300 had already kicked into gear, pulling 
the toxic gas from the air and through the scrubber where 
Safetysorb chemisorbant media neutralized it, releasing 
only purified, clean air into the building
