With nearly 60 years experience and more than 700 reactors and items of special apparatus installed worldwide, DWE® products take the pole position when it comes to apparatus related solutions and engineering for the chemical and petrochemical industry, refineries and research in physics. The formal merger of MAN DWE and MAN Turbo AG with MAN Diesel & Turbo SE, finally completed in 2010, creates the opportunity for us to strengthen and extend our position in the market. The combination of know-how is generating wide-ranging synergy effects.

Two strategic fields form the core of all our activities

On the one hand reactor engineering for the chemical industry, on the other hand apparatus and component
construction for both the petrochemical industry and physical research facilities.
