Effox Flextor Mader

What Effox Flextor Mader does

Effox-Flextor-Mader (EFM) is a US-based manufacturer of engineered-to-order industrial dampers and non-metallic expansion joints used in flue gas and process air handling systems. Founded in 1980 and headquartered in Cincinnati, Ohio, the company operates 145,000 square feet of captive manufacturing facilities in the United States and sells its products globally through a regional sales representative network in the US and Canada, supported by three office locations in Cincinnati, Grafton (Ohio), and Terrebonne (Quebec). EFM is privately held and operates as a business segment under CECO Environmental, with General Rubber recently integrated into the segment to extend the product offering into rubber expansion joints, ducting expansion joints, and industrial pinch and duck bill valves.

The company's product portfolio covers seven distinct damper lines (Butterfly, Diverter/Stack Isolation, Guillotine/Slide Gate, Louver, Metal Seat RTO, Poppet, and Radial/Inlet Vane) plus the EFLEX brand of non-metallic expansion joints and the MADER DAMPERS line for machinery operations. Products are specified for high-temperature and chemically harsh environments, with dampers rated up to 1800°F (982°C) and expansion joints rated from -40°F to 2100°F (-40°C to 1149°C). Proprietary elements include the EFM sprocket design for guillotine damper chain drives and DuPont-certified VITON fluoroelastomer supply for low-temperature power plant applications. The company holds ISO 9001:2008, AISC, AWS, CWB, and CE certifications, is an ASME member, and has been a Fluid Sealing Association member for over 25 years.

EFM sells via a quote-based, engineered-to-order model with no public pricing. Revenue is generated from one-time sales of custom dampers and expansion joints to industrial customers, supplemented by an aftermarket stream covering spare parts, repair/retrofit of any damper brand, fabric expansion joint belt replacements, and turnkey installation and start-up services with global technician support. The stated target customer base is power generation utilities (fossil-fired plants, gas turbine, HRSG systems) and heavy industrial operators in petrochemical, cement, steel, and pulp and paper, all of which require emissions control, high-temperature isolation, and flue gas handling in capital projects with long asset lives.
