The Company

EXPERT Transformatorenbau GmbH, based in Lorsch in the southwest of Germany, was founded over 50 years ago and specialises in the construction of water-cooled high-current transformers, rectifiers and chokes.

The exceptional quality and reliability of our products is based on the technical and technological know-how which we have developed over the years combined with the creativeness and outstanding craftsmanship of our staff.

We produce components for DC and AC high-current applications.

One of the characteristic features of EXPERT components is water cooling.

The welding power sources for resistance welding which we design and manufacture for the automotive industry have been setting new standards in terms of technical development from the word go and form the basis for international standards.

Our products have been used for annealing, melting and heating processes in the glass, ceramic and semiconductor industries for many years now.

In addition to standard products, we also manufacture customised solutions.

We are able to guarantee a global presence and an international customer service thanks to our partners and independent representatives.
