Hansestraße 45-49 | 51149 Köln (Porz)

Quality and experience since 1932

For more than 85 years BOUS International Maschinenbau GmbH can look back on a successful company history. In the past decades, the focus has always been on the continuous further development and optimization of almost all types of cleaning and degreasing systems.

The result is impressive. From continuous and spray cleaning systems to pipe washing systems and immersion and ultrasonic cleaning systems. BOUS sees itself as a specialist for solving all cleaning problems. In addition to an extensive standard program, the focus is on versatile special designs according to customer requirements.

BOUS thinks globally, but relies on tradition at its location in Cologne:
From consulting and planning to design and manufacturing to on-site service.

We combine the complete vertical range of manufacture under one roof and would like to invite you herewith to get a personal impression – gladly during washing tests in our in-house, extensive technical center.

  • Certificate for promotion of young talents

    In 2007, BOUS was one of the first 20 companies in Cologne to be awarded the certificate for the promotion of young talent. “Hall 4” with over 2,000 m2 of floor space was added.

  • 80 years of BOUS

    In 2012, BOUS celebrated its 80th anniversary and, with 46 proud employees, was able to draw on the most extensive standard program of aqueous cleaning systems and degreasing systems on the market. In doing so, BOUS gained its extensive customer base through the almost complete vertical range of manufacture united under four roofs: own design, own tank construction, own control construction, own final assembly, own service.

  • International scope

    On October 01, 2020, the company was taken over by BOUS International Maschinenbau GmbH with the aim of further growth with an increased international focus.
