ATEX DUST Motors
ATEX Dust Explosion-Proof Electric Motors
The ATEX Category (or Zone): for Zone 22 conductive or non conductive dust must be specified.
Maximum permissible surface temperature.
Our 3D range of motors can be derived from our standard range (certain modifications must be performed)
Our 2D range of motors in flameproof enclosure are also available at short lead times.
Two groups are referred to in the ATEX 2014/35/EU directive: I and II. Both groups are subdivided into categories. These categories indicate whether a device or protection system can be deployed in a possibly explosive atmosphere with gas, mist or fumes (G) or with dust (D).
group I: = mining industry
group II: = other locations
Category 1D Zone 20
Category 2D Zone 21
Category 3D Zone 22
Electric data of these electric motors are the same as the standard line of the RNseries. Electric motors can be ordered with contract variations Ex II 2D through BG 160Ex II 3D through BG 315. Other construction sizes are available upon request.
For all Zones (Gas and Dust) please specify:
- Whether the motor is to be frequency inverter controlled.
- Any specific model/execution is required
The ATEX directives do not apply to:
- Sea vessels and mobile offshore installations or for the equipment intended to be installed on board of sea vessels or offshore installations. They all must comply with the IMO(International Maritime Organization) convention.
- Means of transport not intended for explosive atmospheres.
