ESW Group, founded in 1998, operates in the environmental services sector with a focus on automotive emissions technology. It began as an R&D enterprise and later developed a wire mesh based catalyst intended for diesel, gasoline, and alternative fueled engines, aiming to deliver emissions reductions with improved durability over conventional catalysts. The company has obtained California Air Resources Board verifications for multiple products, including ThermaCat and ThermaCat-e, and in 2013 added four additional on-road verifications to its CARB portfolio. Headquartered in Montgomeryville, Pennsylvania, ESW Group positions itself in the automotive emissions market by supplying verified aftertreatment solutions. The firm expanded its operations with a new production facility in Montgomeryville in 2017 and launched the Skyline aftermarket diesel particulate filter line in 2018, illustrating a move toward aftermarket components for heavy duty vehicles.
