The Company Elfri since 1981 has been manufacturing electric and electronic products. During these years, besides the standard transformers we widened the range of products for industrial automation becoming a supplier with excellent references.

Thanks to the matured experience, 10 years ago we conceived a fire-stop door magnet for holiday cruiser.
STOP’s range was the natural development that includes also models for civil application.

New solutions and new products research is the main target of our organization. New raw materials are continuously tested in order to offer to the market competitive and quality items. Furthermore, to guarantee an excellent supply, the products are carefully checked before shipment. Compromises that could damage the quality of the products are not allowed: this is our business policy.

Since 1981 we deal with design and construction of electromechanical parts. Internally we realize the windings, the assembly of static electrical machines and their testing.
