Solutions for Air Quality—Across Industry

Because of our expertise in fired-heater design and combustion technologies, OnQuest has developed a complementary expertise in solutions for air quality management and pollution controls. Moreover, our engineers have deep familiarity across industry, including in the design, engineering, and fabrication of SCRs and customized thermal oxidizers.

Thermal oxidizers are particularly appealing as a cost-effective solution for companies facing challenges in adapting industrial processes to comply with evolving air emissions regulations. This includes plants with furnaces, kilns, or fired-heater applications. Our professionals can review and propose specific applications for companies in a range of sectors, including for odor control and ethanol suppression.
