Haldor Topsoe, a world leader in catalysis and related process technologies headquartered in Denmark, and Unifrax, New York-based manufacturer of speciality fibre products, have announced the signing of a partnership agreement. The partnership signifies a joint effort to market a new line of catalytic filter candles to the global market.

The new line will be known as TopFrax filters. It will offer improved catalytic filters, high quality, well-engineered products and technical guidance to customers in a wide variety of industries such as cement, biomass, glass, waste incineration and metal production.

David E. Brooks, Unifrax President and CEO said: “Unifrax is proud to partner with Haldor Topsoe, a world leader in developing catalysts to solve a range of emission control problems. The commercialisation of TopFrax™ filter candles is in alignment with our company mission of helping customers reduce emissions and save energy. The partnership will help both companies better serve the customer by providing access to a complete hot gas filter portfolio and extensive product support worldwide.”

Important features of the TopFrax filters include: high efficiency filtration of particulate matter (+99%), NOX removal efficiency (+95%), low ammonia slip, and filter porosity above 80%. TopFrax™ filters have a temperature use limit of 400°C (750°F), are compatible with sorbents, non-combustible, and corrosion resistant. These innovative, high quality candle filters provide equipment builders and customers a distinctive technology, merging the removal of NOX, VOC, CO, dioxin and particulate matter in one integrated process. Designing pollution control equipment around TopFrax™ hot gas filters saves CAPEX and OPEX and decreases the footprint of the installation while providing longer energy savings and service. 

“The TopFrax™ product line is the first in the world to introduce a combined process for removal of NOx, VOC, CO, dioxin and particulate matter, enabling customers to meet increasingly stringent regulations in a cost effective way. The partnership offers exciting possibilities for both parties, not only in terms of marketing the new catalytic candle filters, but also in developing other products together in the future,” commented Bjerne S. Clausen, CEO of Haldor Topsoe A/S.
