Severn Trent Services’ EST™ dry emergency scrubbers are engineered to meet national codes for the mitigation of hazardous gas releases from pressurized 150-pound cylinders and one-ton containers of chlorine, sulfur dioxide, ammonia and other toxic gases. Dry scrubbers are safe, user-friendly, low maintenance systems tested and proven for use in municipal and industrial applications where the potential exists for the accidental release of heavier-than-air hazardous gases.
The EST Type DES dry emergency scrubber is used to scrub the entire contents of an overfilled one-ton container at the rate of 3000 CFM. For smaller containers like 150-pound cylinders, the EST Type DSH dry scrub house system will exhaust and clean air from the contaminated room at the rate of 400 CFM.
Both the EST Type DES and DSH are fabricated from industrial grade Fiberglass-Reinforced Plastic (FRP) to provide internal as well as external corrosion resistance over many years of operation and exposure to harsh weather conditions. In addition, these dry chlorine scrubbers do not require liquid chemical leak containment or double wall vessel construction and operate at sub-zero temperatures without the use of heaters.
EST Corporation was acquired by Severn Trent Services in 2001.
