Deploying a computer in a hazardous area - where do you start?
The need to install computer enclosures in hazardous, classified locations is very common. Process control, measuring and recording equipment exists in virtually every manufacturing process. The requirement for explosion proof enclosures is extremely critical.
Hazardous, classified locations are defined as areas in manufacturing facilities where the atmosphere may contain flammable concentrations of gas, vapors or ignitable concentrations of dust or fibers. It is customary for system designers and IT managers to specify the use of a NEMA 4 or NEMA 4X industrial computer enclosure with a pressurized purge system for these environments.
A purge system installed on a hazardous area computer enclosure will prevent ambient particulate or gas from entering the enclosure and ensure the safety of operators and equipment.
