Hazardous Area Enclosures
Expo designs and manufactures a wide range of hazardous area electrical enclosures that can be certified for use in both gas and dust environments.
Enclosures are available in 316L stainless steel or painted mild steel, and can be specified to IP54, IP66 or 4X levels of ingress protection.

Depending on the hazardous area and the equipment installed, Expo can certify the completed enclosure Ex p, Ex e, Ex nR or Ex t. In other cases, Expo can either issue a Manufacturer’s Declaration of Conformity (MDOC) or manage the certification process through a Notified Body.

Most off-the-shelf hazardous area enclosures are designed to keep the potentially explosive atmosphere outside from getting in, rather than to hold pressure. This means that they will probably leak when used for purge & pressurization. This leakage will certainly waste compressed air over the life of the system, and may prevent effective purging altogether.
Expo’s enclosures are specifically designed for purge & pressurization and will deliver the highest performance, low running costs, and enhanced safety.
Building on experience from more than 2,500 enclosure builds, Expo offers two different approaches: PressurEx standardised, configurable enclosures, or Custom enclosures that are engineered to order.
