What Advanced Catalyst Systems does

Advanced Catalyst Systems (ACS), founded in 1988 and headquartered in Maryville, Tennessee, is a vertically integrated manufacturer and supplier of industrial catalyst systems for emission control and gas purification. Its core products span oxidation catalysts, three-way catalysts, SCR catalysts (including ammonia-slip variants), catalyzed diesel particulate filters, DEOXO purification catalysts, methane and propane oxidation catalysts, diesel oxidation catalysts, and industry-standard CATOX solutions for VOC abatement. The technology stack centers on proprietary catalyst coatings, in-house precious metal formulations, and vertically integrated production of sheet metal components and catalyst precursors, supported by a captive laboratory with mass spectroscopy, ICPOES, and FTIR for characterization and postmortem analysis. Notable differentiated offerings include the CatCore line of catalytic infrared heaters — the only catalytic heater with a field-replaceable catalyst assembly, Factory Mutual certified for hazardous locations — and the consumer Platinum Bright Embers product for vented gas fireplaces.

ACS generates revenue primarily through one-time industrial sales of catalyst products, with custom sizing and engineering services billed at $150/hour and 2-year warranty parts covering replacement assemblies and DPF filters. Distribution is direct and sales-led via email, phone, and an online sizing and parts portal (advancedcatalystportal.com); consumer PBE kits are also sold wholesale to fireplace dealers. Customers span the oil and gas (Exxon Mobil, BP Petroleum, Williams Gas), power generation (gas turbines and reciprocating engines from 50 to 20,000 hp), transportation (rail and marine), industrial VOC control, and industrial gas purification sectors, with named logos including Williams Gas and a distribution partnership with Powertherm Maxim silencers. The company was acquired by MIRATECH in January 2026 to form a "catalyst center of excellence" expanding North American and global catalyst manufacturing capacity.
