Fossile power plants

When it comes to fossil power plants, our specialties include air and gas preheaters, shut-off valves and fittings, electric filters, catalytic converter replacement and conveyor systems.

We are your contact when it comes to underlying engineering services and subsequent servicing, retrofitting, optimisation or maintenance. We manage the construction site from the planning stage to successful commissioning.

Furthermore, we supply the necessary spare parts for all tasks.
