Unifrax I LLC of Tonawanda, N.Y., and Denmark’s Haldor Topsoe A/S signed a partnership agreement that marks the beginning of a joint global effort to commercialize a new line of catalytic filter candles. The product family, marketed as TopFrax™ filters, was developed for catalytic hot-gas filtration in the industrial market. The partnership combines the expertise of Topsoe’s leading position within catalysis and Unifrax’s strengths within fiber-filter manufacturing and filtration.

 TopFrax technology offers improved catalytic filters to the global market, providing high-quality, well-engineered products and technical support to customers in industries such as metal production, glass and waste incineration. The catalytic filter candle is designed to remove NOx and particulate matter. It will also be launched in a version capable of removing VOC, CO and dioxin that are generated in many industrial processes.
