Spradow - tradition and innovation

Our toots can be traced back to the early 20th century.

It all started 1913 with the founding of "Armaturenfabrik und Metallgießerei Hermann Wittler" in Bielefeld, Germany. At that time the company was engaged in heating and control technology.

In 1966 the family Wittler founded a subsidiary in a city district called Spradow (near to Bielefeld) named "Apparatebau Spradow GmbH & Co. KG". The mechanical engineering company for customized machines manufactured mainly for the machining industry.

Our today´s core business - the production of high quality measuring systems for hydraulic and pneumatic systems - was started in the early 80s.

1995 we moved to our new 2000 m2 production site in Schloß Holte-Stukenbrock, approx. 20 km south of Bielefeld. 

The positive company development was leading to the founding of today´s company, the "Spradow GmbH & Co. KG" by the former shareholding managing director Mr. Jörg Kraemer, who worked for the company since 1994.

In June 2019, Spradow GmbH & Co. KG was acquired by Mr. Frank Windel. He manages the company as CEO and President together with his sons Tim and Lucas. Thus the future as a customer- and quality-oriented, medium-sized company in Ostwestfalen-Lippe is assured.

Learning from the past to shape the future - that is the unique SPRADOW-philosophy. Zero defect production and highly satisfied customers are our objectives. The very motivated and well trained staff working in a work friendly environment of a family business is a key factor to reach this set objective.
