Hot Gas Filtration

Global regulations have reduced the permissible levels of particulate and hazardous gas emissions, making compliance costly and requiring companies to make substantial investments in pollution control technologies. Unifrax offers unique filtration media technology that addresses the problems related to industrial emissions and high temperature filtration.  The Unifrax “Purefrax™” hot gas filter candles are designed to remove particulate matter with filtration efficiencies exceeding 99%.

In addition Unifrax has entered into a marketing alliance with Haldor Topsoe to provide the industry with catalytic filter candles.  Haldor Topsoe’s Topfrax™ catalytic hot gas filters provide particulate filtration and can be engineered to remove NOx, VOC, CO and dioxins that are generated in many industrial processes.

Key features of both the Purefrax and Topfrax hot gas filters include:  a high temperature use limit, compatibility with sorbents, non-combustibility, and corrosion resistance.

Designing pollution control equipment around Purefrax and Topfrax hot gas filtration media saves CAPEX and OPEX and reduces the footprint of the installation while providing extended service life and energy savings.
