Last month, this company launched an explosion-protection option for enclosures, enabling them to be ideal for analyzers in open-field sites, such as petroleum refineries and chemical process plants. A new inert-gas pressurization system allows the protective cabinets or enclosures (photo) to house laboratory-style equipment that is non-explosion protected, such as analyzers and sensors, in IEC-Ex and ATEX Zone 1, 21, 2 or 22 hazardous areas. The system is certified for use where a hazardous atmosphere might be created inside the enclosure — for instance, a hydrocarbon leak from an analyzer — as well as more conventional situations where a potential hazard is caused by the atmosphere outside the enclosure. — Inertec Instrumentation Ltd., Sarnia, Ontario, Canada
