ATEX ZONE 2 | Category 3G Equipment

Safe under normal operation only (gas)

Atex Zone 2 definition
Atex Zone 2 area is a place in which an explosive atmosphere consisting of a mixture with air of flammable substances in the form of gas/vapour is not likely to occur in normal operation but, if it does occur, will persist for a short period only (from 0,1hrs to 10hrs/365d).

Category 3G explosion proof conversion guarantees an electrical and mechanical protection eliminating any explosion risk for Atex Zone 2 Hazardous Area.

The features include:

  • Temperature class T3, T4 and T5
  • Gas group IIA, IIB, IIB+H2+C2H2 (only for electric trucks)
  • Installation and conversion of components suitable for use in the operating zone
  • Monitoring of surface temperatures
  • Visual alarm signal
  • Load handling device covered with spark-proof material

The use of explosion protection equipment in a potentially hazardous area is a requirement for the Ex supplier and also for the end user in order to be able to work in safety.

Miretti is able to convert equipment to meet Zone 2 requirements for use across the world. Miretti is able to meet the following legal certifications: ATEX (Europe), IECEx (International), CNEx (China), NEC (USA).
