What is ATEX Explosion Proof (ATEX EX)?
ATEX EX (also referred to as Flameproof) is European Explosion Proof equipment certified to ATEX standards. Equipment and protective systems intended for use in potentially explosive atmospheres must enclose all ignition sources. Excalibur Miretti Group supplies ATEX EX equipment that complies with ATEX 94/9/EC Directive. Approved by International Recognized Testing Laboratories, Excalibur Miretti Group's ATEX EX Equipment can be used in designated explosive and hazardous atmospheres.

Temperature Monitoring
Heat generated by equipment may cause gases and flammable materials to ignite or explode.  It is therefore necessary to reduce the temperature of ATEX EX equipment to less than the specified value for operation in a potentially explosive atmosphere and to prevent any sparking from occurring. Excalibur Miretti Group’s ATEX EX Equipment has protection controls for motor surface temperature, fluid temperatures and brake temperatures.

Explosion Proof Enclosures
Explosion Proof Enclosures protect all cabling, wiring, valves and electrical components, ignition system, and battery. An Explosion Proof Enclosure is a case or housing that has been tested and approved to contain electrical components or apparatus. Although the joints of Explosion Proof enclosures will permit the entry of explosive vapors, the strength of the enclosures must contain any internal explosion. The enclosures of Excalibur Miretti Group’s ATEX EX Equipment have been hydrostatically tested for internal explosive resistance to pressures in excess of requirements without failure.

Automatic shutoffs
Automatic shutoffs serve as additional safeguards for ATEX EX Equipment.  Excalibur Miretti Group’s ATEX EX equipment provides automatic shutoffs to ensure against for example: high brake temperature and hot electric motor surface temperature.

Frame Leakage Monitoring
Frame leakage monitoring detects electrical failure before risk of ignition source.  Excalibur Miretti Group’s ATEX EX Equipment prevents possible source of ignition by monitoring frame leakage with an automatic shutoff.
 
Battery Emergency Cutoff Switch
Battery emergency cutoff switch removes all power from the battery supply of the flameproof vehicle. Excalibur Miretti Group’s Battery Emergency Cutoff Switch is an additional source of protection under the operator’s control.
