Dry Bed Absorber

dry_bed_treatment_stage

Passive abatement system offering many advantages due to minimal facility requirements.

Besides an electrical supply, the CT-D only needs compressed air or nitrogen for valve activation. This system has a low facility footprint and safely absorbs the most toxic and harmful gases, such as arsine (AsH3) and phosphine (PH3).

Benefits

Chemisorption of reactive, toxic, and corrosive gases under the highest safety standards

Integrated bypass mode electrochemical clean gas monitoring

Various Container sizes for high versatility
