UltraCat catalyst filters are designed to provide up to 95% of NOx removal at the operating temperatures of most industrial boilers, and destroy dioxins at up to 99% efficiency. The filters are composed of fibrous ceramics with nano-bits of NOx catalyst, embedded throughout the 3/4-in. filter walls. The system uses a reverse pulse-jet cleaning action and is intended to provide ease of operation and maintenance, and low cost. 801-294-5422, Tri-Mer.com.
