2. Application Suitability
MiniPurge
Systems are certified for use in Hazardous Areas, where the Hazardous Area is
non-mining (i.e. above ground) and the hazard is caused by flammable gasses, vapours or dust.
Depending on the model, the systems may be used in IECEx, ATEX Zone 1(21) - Category 2
and NEC 500 Class I, Div 1.
MiniPurge
systems may be used for hazards of any gas group. However, apparatus
associated with the MiniPurge
system, such as Intrinsically Safe signalling circuits and
flameproof enclosures containing switching devices may be limited in their gas group. The
certification documentation supplied with any such devices must be checked to ensure their
suitability.
This system is designed for use primarily with compressed air. Where other inert compressed
gasses are used (Nitrogen, for example) the user must take suitable precautions so that the
build-up of the inert gas does not present a hazard to health. Consult the Control of Substances
Hazardous to Health (COSHH) data sheet for the gas used. Where a risk of asphyxiation
exists, a warning label must be fitted to the Pressurized Enclosure.
The following materials are used in the construction of MiniPurge
systems. If substances that
will adversely affect any of these materials are present in the surrounding environment, please
consult Expo for further guidance.
Materials of construction:
Stainless Steel
Aluminium
Acrylic
Mild (carbon) Steel
