Since 1931 Walther Trowal has been developing and producing systems for the refinement of surfaces. Initially focusing exclusively on mass finishing – the term “Trowalizing” originated from the company’s cable address “Trommel Walther” – Walther Trowal has continuously expanded its product portfolio.
Over time the company has developed a broad range of machinery and systems for mass finishing, shot blasting and coating of mass produced small components.
With the invention of new systems like, for example, drag finishing and the development of special finishing methods for 3D printed components, the company has proven its innovative capabilities again and again.
Trowal develops and implements complete surface treatment solutions that can be seamlessly integrated into linked production systems existing at the customers. This includes the entire process technology, perfectly adapted to the specific surface finishing requirements of the work pieces: Equipment and the respective consumables always complement each other in a perfect manner.
Each individual work piece and each manufacturing process must meet special technical requirements. That is why the experienced process engineers in our test lab, in close cooperation with the customers, develop the optimal process technology for the finishing task at hand. The result: Work piece surfaces that meet exactly the required specification with short processing times and a high degree of consistent, repeatable results.

About us:
j&w Cleaning Systems was founded in may 1998 as a spin-off from the company jaresch&wegener (founded in 1932).
Due to decades of professional experience in the field of engineering and manufacturing steel structures and fan rings for any type of heat exchanger plant, a new idea arose in the 90's - the idea to design cleaning systems for enourmous fouled heat exchangers.
Meanwhile j&w has become the technological market leader on this sector.
In addition to the designing and manufacturing of permanent installed cleaning systems, j&w also offers a cleaning service with its own staff in Europe and in South Africa.
Worldwide we cooperate with distribution partners who offer the
patent-pended j&w cleaning systems and service .
