Emitec Gesellschaft für Emissionstechnologie mbH was founded in 1986. Today, the company is a world leader on the metal substrate market for exhaust gas catalysts and metallic diesel particulate filters for vehicles and mobile machinery. Complete SCR systems round off this product range. Since its foundation Emitec has sold more than 170 million metal substrates of the highest quality with excellent operating report. Emitec is also a long-standing partner of the car, commercial vehicle, marine and motorcycle industry, the agricultural and construction machinery industry and of many engine manufacturers.

The company employs around 900 people in Lohmar and Eisenach, Germany, in Faulquemont, France, at the Fountain Inn plant in South Carolina, USA, at the plant in Pune, India and at several application engineering offices around the world. Development centers are based in Lohmar, Eisenach and Denmark. The company’s customers include the major car, truck and motorcycle manufacturers from across the world as well as in the non-road sector producers of tractors, agricultural machinery, construction equipment, ships and diesel locomotives. Emitec owns over 2,700 patents worldwide, a fact that reflects the company’s innovative strength.

Metallic Catalyst Substrates

Emitec metal catalyst substrates are made with ultra-thin walls and high open frontal area, yielding low pressure losses. Our metallic honeycombs are characterized by high geometric surface area and unsurpassed thermal and mechanical durability. They have been proven as an excellent solution for automotive close-coupled converters. Due to the thin walls, they are resistant to plugging by soot in diesel applications.

Emitec’s lightweight catalytic converter is enclosed in a shell made from only 0.5 mm thick stainless steel with a bionic—and hence very rigid—structure.

NoNOx SCR Division

In 2010, Emitec expanded its product and system range in the field of selective catalytic reduction (SCR) technology: With the acquisition of Grundfos NoNOx, Emitec can offer complete SCR systems including substrates, urea dosing pumps, logic controls—all integrated into a system.

Emitec NoNOx division designs, develops and manufactures urea dosing units that reduce nitrogen oxide in the emissions of combustion engines. SCR dosing systems developed by Emitec are offered for passenger cars, light-duty commercial vehicles, as well as the heavy-duty commercial vehicle and non-road sector.
