ATEX Zone 0, 20, 1, 21

A hazardous area is defined by the likelihood and concentration of an explosive atmosphere being present in a specific area, and is split into zones depending on the type of atmosphere present.

At indEx we have a wealth of knowledge and experience in providing enclosure solutions for hazardous areas.

For zone 1 & 21;- intrinsically safe terminals, with full assembly and certification for zone 1, and protection by enclosure for Zone 21.

indEx enclosures are ideally suited to intrinsically safe zone 0, 1 Field Bus systems. We are able to provide cost effective, robust and durable solutions where the enclosure just needs to house and mount the FB unit.

Our indEx engineering and design team has many years of experience in the design and build of zone 1 and 2 pressurized/purged systems, and can adapt our enclosures to suit most px or py solutions.

NB. For zone 1, 21, indEx can provide a design and build service. Enclosures can then be tested by third party EN test houses such as SIRA for solutions such as high voltage, field bus systems, control panels and fibre optic control enclosures, at additional cost.
