The history of Magnetrol goes back to the 1930's, when a Chicago - U.S.A. based manufacturer of boiler systems, called Schaub Inc. was in need of level controllers for its systems.
The level switches and controllers developed for this purpose, ultimately also became attractive instruments for installation in applications and process installations, other than the own Schaub systems, and gradually started to be marketed under the name Magnetrol.
Driven by the many European projects for offshore and nuclear power plants, Magnetrol started looking at the overseas market as a major new investment to expand business.
