Explosion Proof Motors - EEx d / EEx de (ATEX) 

High Efficiency - IE2

Applications
Environments containing flammable gases or vapour continuously, intermittently or periodically in enough amount to generate explosive or flammable mixtures arising out of repairs or maintenance services.

The most common locations of Zone 1 and 2, group IIA and IIB are those where the following gases are found present: oil, naphtha, benzene, ammonia, propane, diethylic ether, acetone, alcohol, industrial methane, natural gas.

The main applications include fans, blowers, crushers, conveyor systems, mills, cranes and other applications located in areas that require explosion proof motors

Classification

IEC Standard: 
Zone 1; Group IIB

CENELEC Standard:
Group IIB; Category 2

Note: The classification in Zone 1 means that the motor is suitable to operate also in Zone 2 once Zone 1 represents an operating condition worse than Zone 2. The same applies to Groups and Categories: EEx d and EEx de motors are suitable to operate also in Group IIA and Category 3.

Certification
In Europe, WEG explosion proof motors meet ATEX Directive 94/9/EC certified by PTB and product certified by CESI -Centro Elettrotecnico Sperimentale Italiano S.P.A. The CESI certificates of conformity for explosion proof in flameproof enclosure “d” and “de” as per EN50014 / EN50018 are:

  • EEx-d: Explosion proof motors (class of temperature T4)
  • EEx-de: Explosion proof motors with increased safety terminal box (class of temperature T4)
