ATEX C' Zone 22 (category 3D) non-conductive dust
In the UK from July 2006 the onus was placed upon companies to ensure that all equipment within their organisations is suitable for the environment in which it is being used. This was aimed primarily at areas where there may be a possibility of a combustible atmosphere being present, even for short periods i.e. less than 10 hours/year.

People normally associate such atmospheres as being gases, mists or vapours. However there are various industries where a non-conductive dust mixed with air in the right proportion can become potentially explosive. It is these areas where the Craig & Derricott ATEX Group II (Zone 22 equipment can be used to help you comply with Health & Safety regulations.

The 25A & 32A items are supplied in heavy duty die-cast aluminium enclosures, the 63A versions are supplied in door interlocked sheet steel housings.
