Directive 94/9/EC or ATEX specifies new regulations for explosion protection for all types of devices for the European market.

This directive applies to gearmotors and motors. As of July 1, 2003, directive 94/9/EC applies without restriction to the use of gearmotors and motors within the European Union. Other European countries, such as Switzerland, have also adopted this regulation.

Scope

SEW-EURODRIVE now supplies explosion-proof gearmotors and motors only in accordance with the corresponding ATEX directive. This also applies to options and accessories in the explosion-proof version.

Depending on their features and dimensions, explosion-proof gearmotors and motors are suitable for:

Potentially explosive gas atmospheres, zone 1 or 2

Potentially explosive dust atmospheres, zone 21 or 22

SEW-EURODRIVE offers gearmotors and motors of categories

II2G

II2D

II3G-D

II3D

For use in zones 1, 21, 2 and 22

Your advantages

SEW-EURODRIVE has been audited and certified to ATEX100a.

Drives in four different categories are available

	Explosion-proof drives
	Operating systems and machines in areas with potentially explosive air / gas or air / dust mixtures requires special measures. If mixture formation cannot be prevented, specially protected drives must be used. Applicable standards and regulations govern the use of equipment within existing hazard zones. They also prescribe the quality prerequisites that must be met by drive manufacturers.
