The Miretti’s technological and engineering effort to Atex Explosion Proof protection of various machines for underground applications: different vehicles, different types of use, differen sizes (small/heavy duty/compact layout), different scope of supply, different brands etc…
In the Atex field, the underground projects need often customized explosion proof conversions against any risk of explosion!

Miretti Team is flexible in response to the market demands and is reliable in offering 100% Ex customized solutions with “ad hoc” designs and projects. Thanks also its Technical Office and Certification Department, both inside the Company itself, Miretti can gain insight about any eventual problems that might arise, however complex, such as spaces or structural limits.

The Explosion Proof is often a forced choice (It is the legislation that requires you to follow certain standards of protection!!!). The conversion is a meticulous procedure. For each special vehicles and for each equipment in general, the most appropriate “explosion-proof” solution must be identified considering the characteristics of each brand, the classification of work area and gas and/or dust, the temperature.

Miretti always works to ensure that the Explosion Proof conversions are “at the service” of the equipment on which they are mounted.

Tunnelling and Material Handling applications are always part of Miretti’s heritage. Since 70’s we are fully committed to work as partner of the most important international contractors and OEM’s.
