Elektrotechnik Wolfgang Reiser, the forerunner to Reiser Systemtechnik GmbH, was founded in February 1980 and succeeded as a company dealing with cable packing, mounting of heat exchangers and producing controls for laser equipment.

In 1988 Elektrotechnik Wolfgang Reiser expanded by adding the production of mechanical components for heat exchangers, mechanics for control units and front panels. The extension of facilities allowed in-house design and development.
