Cable and pipe seals for hazardous locations

Cable and pipe seals for hazardous locations

Roxtec Ex cable transit devices are certified according to the ATEX directive and the IECEx, International Certification Scheme, for use in potentially explosive atmospheres. The seals efficiently help you avoid the risk of explosion.

Approved for Ex e and Ex tb

Roxtec Ex solutions prevent ignition of explosive atmospheres. Typical applications are Ex e and/or Ex tb rated electrical enclosures, such as transformers, motors, generators and junction boxes. Ex e means increased safety for explosive gas atmospheres, and Ex tb means protection by enclosure for explosive dust atmospheres.

Zone classification

Hazardous areas are rated into zones based on the possibility of occurrence of an explosive atmosphere. It is the obligation of the owner or the operator of a facility to ensure that the zone classification is done by authorized personnel.

Zone 0 (gases)
Zone 20 (dust)
Flammable material present continuously or for long periods
Zone 1 (gases)
Zone 21 (dust)
Flammable material present occasionally in normal operation
Zone 2 (gases)
Zone 22 (dust)
Flammable material present in abnormal conditions only for short periods
Highlighted zones = Permitted zones for Roxtec Ex products
