Explosion protected drive solutions by NORD
Drive systems for explosion hazard areas
of Zones 1, 2, 21, or 22
NORD supplies customised explosion protected motors and geared motors. Systems based on top quality components are designed according to application in compliance with specific customer requests.
- Versions and equipment according to individual requirements
- Configuration processes validated as per ISO 9001
- Safe, SAP-supported modular system
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
