Smart engineering since 1842


Assorted transformers and reactors for LV and MV applications. We provide you the experience and knowledge for propulsion, thrusters, drilling and distribution transformers for the marine and offshore applications.  

The IP44-IP56 transformers AF cooling systems guarantee a substantially longer life due to the optimized control of the internal temperature. The transformers for marine and offshore applications are designed, manufactured and approved by marine standards including ABS, Bureau Veritas, DNV, RINA, and Lloyd’s shipping register. These products have been recognized on military naval applications by demanding tests of certificate institutes (i.e. CETENA approval) which check the resistance to vibrations, collisions, shocks (30G), etc.
