Paint and Coatings VOC Emission Control

Colt Technologies designed and installed two MAXIM™ Regenerative Thermal Oxidizers (RTOs) at a new railcar manufacturing facility. Each RTO controls Volatile Organic Compounds (VOC) and paint spray booth emissions from 40,000 scfm of exhaust air from paint spray booths and interior lining operations at the plant.

The RTO systems reduce VOC emissions by 98% utilizing custom ceramic heat transfer media to avoid particulate issues from the paint booths, and to improve heat transfer efficiency to minimize natural gas fuel costs.
