Engine and Alternator

The engine-alternator coupling represents the heart of an Onis Visa genset.

Visa has always cooperated with the most qualified manufacturers to provide the perfect coupling and offer a product that aims at the highest quality standards.

The BiG FOX is equipped with engines manufactured by German company Deutz, coupled with Stamford alternators.

On www.visa.it is the list of the currently available combinations.



- All the baseframe parts are made from top quality S235JR steel in accordance with UNI EN 10025-95 and subjected to strict seal tests before assembly

- Each part is painted with thermosetting powder with a specifically selected polyester resin base to make them highly resistant to atmospheric agents; the pigments are distinguished by very high stability against light and heat.

- Engine anti-vibration system: crossbeams fitted with fuel and lubricant-resistant vulcanised rubber anti-vibration mounts are bolted onto the baseframe.

- The canopies are built from modular elements that are assembled together using special structural rivets; this technique has eliminated the need for welding and allows each part to be fully coated with paint prior to assembly, so as to exclude the possible formation of oxide on the attachment points of the various parts, in addition to providing absolute rigidity of the structure;
