PMFG, Inc., through its subsidiaries, provides custom-engineered systems and products primarily to natural gas infrastructure, power generation, and refining and petrochemical processing markets worldwide. The company operates in two segments, Process Products and Environmental Systems. The Process Products segment offers separation and filtration systems and products that improve efficiency, reduce maintenance, and extend the life of energy infrastructure by removing liquid and solid contaminants from gases or liquids, as well as by separating different liquids. This segment’s systems and products include vane separators, centrifugal separators, filter separators, three-phase separators, absolute separators, fuel gas conditioning systems, gas filters, nuclear plant steam separators, inlet air treatment systems, pulsation dampeners, heat exchangers, industrial silencers, and waste water treatment systems. The Environmental Systems segment engages in designing, engineering, fabricating, and selling environmental control systems and products for air and noise pollution abatement. This segment offers selective catalytic reduction systems that convert NOx emissions produced by burning hydrocarbon and organic fuels, such as coal, gasoline, natural gas, wood, grass, and grain into nitrogen and water vapor; and oxidation systems, which oxidize carbon monoxide and various volatile organic compounds into carbon dioxide without the use of additional chemical reagents. Its customers include equipment manufacturers, engineering contractors, and owner-operators of energy infrastructure. The company markets its products directly to customers, as well as through independent sales representatives. PMFG, Inc. was founded in 1933 and is based in Dallas, Texas.
