Manufacture of plants and apparatus





“The best things come in small packages,” may be the best description for Wissel, a company with about 15 employees. Small, however, is not a term that can be applied to our range of products and manufacturing, because at the point where large companies have to turn you down, Wissel extends its hand as a flexible and reliable partner.

We manufacture according to your needs!

As an experienced and reliable partner, we use your sketches and drawings to provide you with made-to-order production of pipeline systems, containers, condensation traps and vacuum chambers in various lengths and types.

In addition to specialising in the production of ready-to-assemble vacuum pipes in diameters up to 800 mm and fully assembled pumping stations, our range of services also includes the bending, brazing and soldering of non-ferrous metals and high-grade steels, as well as machining.

In the last few years, we have also been working even more closely with our customers and allowing them to benefit from our ability to manufacture prototypes. Both renowned manufacturers as well as research facilities place their trust in our employees’ expertise and experience to break new ground and make innovative ideas a reality.

Thanks to the seamless connection between production engineering, warehouse logistics and the shop floor, as well as our use of in-house components to manufacture our piping systems, we are able to guarantee cost-effective project execution. The resulting flexibility, as well as the cost/benefit advantages, allow our loyal customers to benefit from short lead times and fair pricing.

We provide you with parts manufactured from steel, high-grade steel and non-ferrous metals as well as finishes and various documented testing procedures. Take a look at some of the highlights:
