Exhaust gas cleaning = PURItech

As a specialist for exhaust aftertreatment systems, PURItech is one of the leaders in the field of retrofitting in Germany and Europe.
Founded in 2001 by Bernhard Kahlert, the company experienced rapid growth with its innovative diesel particulate filter systems retrofitted to construction machinery, trucks, buses, trains and even ships.

PURItech managed to become the exclusive partner of the market leading supplier of trucks and upgraded thousands of vehicles for a wide range of well-known manufacturers. The many international tenders won testify to the quality of our products and employees.
