Our company, which was established in 1966, has for many years specialized in the development of environmental solutions, chiefly in the field of automotive technology.

Today, our main line of business is the development and production of systems for monitoring and controlling the after treatment of engine exhaust gases.

Our best-known product is the DYNTEST system, which is in demand all over the world. It can be fitted to trucks, buses, construction vehicles and agricultural vehicles of all makes. Our business strategy has been to concentrate on developing devices that can be retrofitted to large diesel engines. We supply tried and tested systems for large commercial and industrial vehicles, and we also develop and optimize products and procedures for our sales partners.

CPK also provides systems for the OEM market.
