Product Overview

The EX750 CAT2 Barrier can operate in an area that is deemed to be a potentially explosive atmosphere, an explosive atmosphere can be caused by flammable gases, mists or vapors or by combustible dust. When these dangerous substances combine with air, under atmospheric conditions and ignition has occurred, the combustion spreads to the entire unburned mixture.

How to reduce the risk of an explosion?

Many workplaces may contain, or have activities that produce explosive or potentially explosive atmospheres. Examples include places where work activities create or release flammable gases or vapors, such as vehicle paint spraying, or in workplaces handling fine organic dust such as grain flour or wood.

  • Prevention & Reduction of the number of dangerous substances that cause the explosive atmosphere
  • Prevent ignition source

Mechanical & electrical equipment that operates in zoned areas should comply with the requirement of the ATEX directive & the IECEx standard

Technical Specifications

The barrier comes with an IP66, ATEX / IECEx Ex d explosion proof certified enclosure to enclose the control system. Please note that any access control systems / push buttons etc. must be fully compliant with the same ATEX / IECEx classifications if mounted on or in the vicinity of the equipment. Where the barrier control point is remote from the installation, we strongly recommend the fitting of a recordable CCTV system.
