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 .
