To make a difference in this sector it is necessary to implement technical innovations and systems designed to be at the service of the equipment and the needs of the end user. Miretti work on “cut and tailor-made” solutions for each individual engine. The solutions must have minimal impact on the machine and must also be able to preserve its characteristics, functions and performance as much as possible. It is also important to develop protection methods that allow you to make use of the most advanced technology available on the market.

Placing R&D and innovation at the service of its customers needs means overcoming limiting conditions to make better alternatives accessible that were previously precluded. This too is the philosophy of POSSIBILITY

Tier 3 and 4 engines made explosion proof to FM & U.S Coastguard sagety regulations for USA Market

One application of recognized risk is inland tank barges and vessels transporting cargoes of fuels, chemicals and other flammable and combustible products.

Today’s engines, required to meet the exacting Tier 3 and 4 emissions standards by authorities including the U.S. Coastguard, almost always involve electric and electronic management systems that could prove a source of ignition if in contact with a flammable atmosphere.
Miretti Group can explosion proof the electric and electronic components of most Tier 3 and 4 compliant engines.

But diesel engines also have many other mechanical sources of ignition. Miretti Group offers the option for complete and fully compliant engine explosion protection minimizing any risks when installed on Tank Barges and other vessels needing to carry flammable materials and required to enter hazardous and potentially explosives atmospheres.
