Esw Group

ESW Group® was founded in 1998 as an R&D company with the goal to develop ceramic based catalytic converters for the automotive industry. In 2001, ESW Group acquired the assets and proprietary technologies of an emissions testing and catalyst development company in PA. Through this acquisition, ESW Group began the research and development of a wire mesh based substrate technology that could be adapted for usage on diesel, gasoline, and alternative fueled engines. ESW Group became the first to overcome the technical difficulties of producing a commercialized wire mesh based catalyst for internal combustion engines of all sizes. This unique proprietary catalyst product achieves, in most applications, superior emissions reductions and structural durability to current conventional technologies available in the market. In 2009, ESW Group obtained a Level verification from the California Air Resource Board for the ThermaCat product for both on-road and off-road applications. In 2012, ESW Group obtained a Level CARB verification for the ThermaCat-e that broadened the applicable vehicle universe to include on-road EGR engines. In 2013, ESW Group added four new on-road verifications to its product portfolio of CARB verified technologies. These include the LongMile®-S, the Horizon®, the Longview® and the Vista®.
