The Avon ATEX CAT3 Barrier is a rising arm vehicle control barrier designed to operate in the oil & gas, petrochemical, pharmaceuticals, chemicals & fertilizer industries. The barrier cabinet is categorised as an ATEX flameproof EX d enclosure and is certified to ATEX Group
2 Category 3.
The barrier is able to operate designated zone 2 hazardous environments or potentially explosive atmospheres: the working components are housed in a flameproof enclosure designed to withstand the pressure developed during an internal explosion and prevent the transmission of the explosion to the explosive gas atmosphere surrounding the enclosure.
Key features & benefits
The Avon EB750 ATEX CAT3 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 vapours or by combustible dusts. When these dangerous substances combine with air, under atmospheric conditions and ignition has occurred, the combustion spreads to the entire unburned mixture.
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 vapours, such as vehicle paint spraying, or in workplaces handling fine organic dusts such as grain flour or wood.
Mechanical & electrical equipment that operate in zoned areas should comply with the requirement of the ATEX directive.
A standardised marking scheme is applied to identify equipment suitable for a specific location.
