Our state-of-the-art emissions testing facility is equipped to perform a wide variety of EPA, CARB and EU compliant services.

With a combined total of over 100 years experience, ESW America is equipped to perform EPA and CARB emissions certification testing, durability testing, performance testing and fuel economy testing for a wide variety of engines and chassis.
Our parent company, ESW Group® was founded in 1998 as a research and development 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 Pennsylvania. 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 III+ 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 III+ 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 CARB verified technologies. These include the LongMile®-S, the Horizon®, the Longview® and the Vista®. The addition of these leading CARB verified products have placed ESW Group as the leader in cutting edge Level III+ diesel emission control technologies in North America.
