Dürr CTS and Arglass have successfully commissioned an advanced exhaust air purification system at the Arglass facility in Valdosta, now fully operational under real production conditions.

Installed on one of the plant’s oxy-fuel furnaces, the system is based on Dürr CTS’s catalytic candle filter (CCF) technology, designed to simultaneously remove particulate matter (dust) and sulphur oxides (SOx). The 2-in-1 filtration system achieves up to 90% pollutant reduction, supporting compliance with strict environmental standards while improving overall process efficiency.

A key technical feature is the modular configuration of seven filtration units operating in an “n-1” setup. This allows one module to be taken offline for maintenance without interrupting plant operations, ensuring continuous furnace performance and eliminating downtime during servicing.

The project, part of a greenfield development, required full on-site delivery, including system integration, commissioning, and technical support. Dürr CTS coordinated a global supply chain, delivering high-end components from Europe to the U.S., balancing performance with cost efficiency.

Following its initial phase in 2025, the installation now serves as a reference project for the North American glass industry. While new to the U.S. market, the technology is backed by multiple CCF installations worldwide, particularly in glass production.
