Histroy

The company was founded on May 22, 1957 as the Austrian subsidiary of  German Messwandlerbau GmbH in Linz. Between 1971 and 1974, the company relocated to Gallspach and expanded the plant in two stages. The instrument transformers were manufactured under a license agreement with Messwandlerbau GmbH Bamberg (FRG – Federal Republic of Germany).

Even today, MWB devices can still be found in testing laboratories and institutes around the world. Some of them regularly return to us for calibration. This demonstrates the long-lasting quality of our products from the very beginning.

In 1994, MWB Bamberg was acquired by a foreign investor. The closure of ÖMWB in Gallspach was imminent.

Most MWB products was shifted to other companies within the group of new investor (Trench, Haefely).

A small team led by Managing Director Mrs. Doblhofer reached an agreement with the investors for a management buy out, allowing them to continue production with a smaller team and limited portfolio. On 17th October 1994, several employees purchased the site in Gallspach and founded EPRO Gallspach GmbH. The company started to operate 1st of November1994 with 17 employees. Some of these employees are still with the company today – this shows the loyalty and satisfaction within our organization.

Of course, the production volumes from the earlier MWB days could not be maintained, as the product portfolio shifted from serial production to custom-made, high-precision testing equipment.

Since 1994, we have had the privilege of supporting numerous projects, developing testing equipment for our clients, and manufacturing them tailored to their individual needs.

To enable 100% production in Gallspach, a vacuum casting facility was added to the company building in 2006/2007. This investment made it possible to produce the insulating cylinders for our test bay equipment in house and we could expand our business to the casting of cable terminitions and cable joints for leading cable system manufacturers.

Our focus also always was development. Together with a French developer, a complete transformer testing system and two products for measuring the insulation of solid insulating materials were developed. From these systems, additional customer-specific developments emerged, such as the TRAFO TEST Coil – a measuring system that allows pre-testing of cast resin transformer coils before assembly – and the INSULATION TEST Endurance System, an aging test for insulating materials.

In 2021/2022, the outsourced electronics development in France was brought back in-house to Gallspach. With a small team, further developments and projects are now being realized centrally in one location.

Since June 2014, the company EPRO Gallspach GmbH has been wholly family-owned.
