Explosion protected drive solutions by NORD

Drive systems for explosion hazard areas

of Zones 1, 2, 21, or 22

High Flexibility

  • Motors optionally designed for inverter operation
  • Direct mounting of the motor to the gear unit is possible in many cases
  • Depending on the zone, optional external fan, backstop, brake
  • If desired, a combined dust/gas explosion protection is available (not suited if explosive gases and particles are present simultaneously)
  • Systems for ambient temperatures up to +60 °C
  • Worldwide shipping with documentation in more than 20 languages

Dust

There are several zones of explosion protection in dust atmospheres:
Zone 22: Rare occurrence of explosive atmospheres
Zone 21: Occasional occurrence of explosive atmospheres
Zone 20: Constant or frequent occurrence of explosive atmospheres
