100 years FRIZLEN

In 2014 the specialist in power resistors celebrated its 100th anniversary and proudly looks back on a long tradition of producing electric power resistors.

  • PHOTO GALLERY 100 years dynamics through resistance
  • Founder Carl Frizlen

    Electrical engineer Carl Frizlen founds Elektron, today FRIZLEN GmbH u. Co KG., in Swabian Ludwigsburg in 1914.

  • Head office in Ludwigsburg from 1922 to 1971

    In the first decades the company is located in a baroque town house in the centre of Ludwigsburg.

  • First class quality instruments

    Only a few years after foundation the first variable resistors and starters for electric motors are produced.

  • Süddeutsche Elektron AG

    In order to raise capital necessary for enlargement of product portfolio, in 1922 it is converted into a share company, Süddeutsche Elektron AG.

  • Starters for the German shipbuilding industry

    In the 1950s the firm widens its product portfolio. Starters for DC motors on ships become an important branch.

  • Family businessmen

    Karl Frizlen and Ernst Gehrung, the founder’s son and grandson, manage the company from 1960 and respectively 1980 on. From 1982 on the company operates under the name FRIZLEN GmbH u. Co KG.

  • New building in the open countryside

    In 1972 the Frizlen KG relocates to nearby Murr, thus paving the way for growth in the coming decades.

  • Robust and cost-effective

    In 1978 FRIZLEN introduces steelgrid resistors into the market – an inexpensive product for high dissipation.

  • Electronics entering drive technology

    Since the 1980ies braking resistors for frequency converters represent the most important product. Hereby electric drives are being speed-controlled.

  • Launch of flat resistors

    In 1999 FRIZLEN introduces wirewound flat resistor in protective housing and compact design.

  • New sheet metal working plant

    The construction of the sheet metal working plant with fully automated punching machines is the biggest single investment in the company's history.

  • FRIZLEN production site today

    After several structural enlargements today’s production site comprises 6000 sqm.

  • The FRIZLEN product portfolio

    FRIZLEN develops and produces power resistors for dissipation power range of 10 W to several hundred kW. 100 committed employees make sure that the customers are satisfied.

  • The management team

    Ernst Gehrung and his daughter Julia Horn manage the company. FRIZLEN is a leading manufacturer of power resistors.

Start-up in the Great War - control resistors for early electrotechnology

In 1914 electrical engineer Carl Frizlen founded the Elektron GmbH in Ludwigsburg, Southwestern Germany - a company today operating as FRIZLEN GmbH u. Co KG. In 1922 the young company started manufacturing regulators and electrical starters - a business unit which can be seen as direct antecessor of the current product portfolio of FRIZLEN. In order to raise the necessary capital, it was converted into a share company, Sueddeutsche Elektron AG.

Starters for German ships and ripe bananas

In 1950 the founder's son, Karl Frizlen, recognised the importance of shipbuilding as a market are for DC current electrical starters and successfully built up this product branch. 1960 the company's founder retired and Karl Frizlen took over the management. The 1970ies had been affected by the relocation from narrow production site in Ludwigsburg to the current location in nearby Murr moving into new bigger buildings. At the end of the decade the production of steel-grid resistors started - an inexpensive product for high dissipation.

Braking resistors for speed-controlled electric drives

Ernst Gehrung joined the management team in 1980, representing the third generation of the family. He boosted the sale of power resistors for speed adjustment and braking of DC and AC motors and achieved a strong growth of the company. The most recent development was focussed on a significant extension and modernisation of production capacities. In 2011 Julia Horn joined the management team representing the fourth generation of the family. Today FRIZLEN is a specialist in power resistors in various designs for different fields of application, reacting promptly on the customers' needs. The strengths that gave FRIZLEN a very good market position are highly qualitative technical advice, high development expertise and a very flexible production.

Optimistic outlook into the future

As most traditional and single significant independent manufacturer we are well set for the future. Current trends represent further opportunities: many future technologies such as renewable and decentral power generation and electromobility imply new fields of application for power resistors. The management is confident being able to achieve stable growth also in the years to come.

Events around the anniversary

As kickoff a press conference took place on May 8th in which representatives of professional journals and of local press participated. The guests got the opportunity to satisfy themselves of the modern production and the company's capability.
In July the anniversary is celebrated with all employees. At the end of the anniversary year customers will be invited to a booth party on the trade fair sps/ipc/drives in Nuremberg in November.
