Hand-crafted systems - made in Germany

While more and more manufacturers are outsourcing production to other countries, we remain committed to our “Made in Germany” seal. We manufacture almost all of our products and parts ourselves in our 8300 m2 facility. 

This means that we can provide our customers with products that meet consistently high quality standards.


JOVYATLAS was founded on 1 December 1945 by Dr Richard Jovy. The first products manufactured by the company were rectifiers for cinemas, frequency converters and inverters. UPS systems and backup power supplies were added to the company’s product range at a later stage.

JOVYATLAS has a well-established commitment to innovation and pioneering development.

Over its 75 year history, JOVYATLAS has grown to become a global company.

The company DR.-ING. JOVY is the legal predecessor of JOVYATLAS GmbH. The company was set up as a sole proprietorship on 01/12/1945, added to the commercial register in 1948 and converted into a GmbH in 1960.

EUROATLAS became a majority shareholder in DR.-ING. JOVY GmbH on 04/05/1979. The company was renamed JOVYATLAS SPECHT Stromrichter GmbH and began doing business with the acronym JAS

JOVY-ATLAS SPECHT Stromrichter GmbH was sold to the American group MagneTek in June 1989. JOVYATLAS became a 100% subsidiary of the MagneTek group through a German holding company, and started doing business under the name MagneTek JovyAtlas GmbH. 

In 1994, JOVYATLAS was acquired by the Carlyle Group and renamed JOVYATLAS Elektrische Umformtechnik GmbH. JOVYATLAS was part of the Power Paragon Group, which was acquired in 1997 by SPD Technologies.

Following the sale of SPD Technologies to global US group L3, JOVYATLAS was part of L3’s Marine & Power Systems division between 1998 and May 2015. 

In June 2015, the entirety of L3’s MSI group was sold to the Finnish Wärtsilä Group.

On 01/10/2020, Wärtsilä sold JOVYATLAS to its industrial holding company Jacob Waitz Industrie GmbH in Kassel. JOVYATLAS was renamed JOVYATLAS GmbH at that time.


Fennenweg 4
26844 Jemgum

JOVYATLAS has been based in the district of Leer in East Frisia near the Dutch border ever since the company was founded in 1945. This location provides our employees with a high quality of life, along with excellent transport links for our company. We are close to the airports in Nüttermoor, Bremen and Groningen. Leer also has excellent links with the Deutsche Bahn rail network.

When the company ran out of room for its production facilities, JOVYATLAS decided to expand outside of Leer. In 2003, the company outsourced its resistor production to the Soltborg industrial park in Jemgum. In 2010, the company moved its materials warehouse to a hall in the “Am großen Stein” industrial park due to a lack of space. Splitting the company into three different locations was always expected to be a temporary measure. In the very same year, the company put a plan in motion to bring all three areas back under one roof and build new facilities.

In 2014, the company moved into its new UPS system manufacturing facility in Jemgum. The site also has an integrated warehouse and shipping area. Since then, all of the company’s manufacturing, warehouse and test facilities have been based in Jemgum. When the new administration building was completed in 2015, JOVYATLAS left its headquarters in Leer and completed its moved to Jemgum. The company’s facility covers a total area of 8,300 square metres, comprising the new office building (1,300 m2), the new manufacturing facility (4,800 m2) and the existing resistor production hall (2200 m2). JOVYATLAS has plenty of room to expand into as the entire site covers an area of approximately 23,700 m2. The new buildings use cutting edge manufacturing and logistics technology to maximise efficiency. A new test facility with solar panels and an energy recovery system has significantly improved the company’s carbon footprint.
