Rigourous quality controls of products has created DRUSCH Trade image.
DRUSCH was dynamic activity applied for High Technology and R&D.

The story of DRUSCH
in short

he company DRUSCH was created in France in 1955 under the name DRUSCH and Co.
Later, the name of the Company became DRUSCH et Cie with a subsidary DRUSCHGmbH in Landau, Germany in 1981 which was transferred in 1990 to Hanover.
The products of DRUSCH were related to high power systems as well as associated products producing magnetic fields and measuring them.
