Killark Hazardous Location Enclosures
Providing a variety of enclosures that are explosion-proof, dust-ignition-proof, and watertight allows the engineers at Killark to directly address many types of hazardous locations. Each hazardous location enclosure model is designed to meet some of the most demanding safety standards certifications issued by such organizations as Underwriters Laboratories (UL), the Canadian Standards Association (CSA), and the International Institute for Frerglass Reinforced Uncrating (IIF) in Europe. The bodies of these enclosures are formed from an array of strong, durable materials like cast aluminum and stainless steel.
The key aspects of Killark enclosures are that they can house many sorts of standard and custom controls, like junction boxes, control panels, and the kinds of instrumentation devices found in chemical and petrochemical plants and other processing facilities. The thing that really sets them apart, however, is how easy it is to not only put all these components inside but also to get inside themselves for maintenance and/or inspection.

Purge System Basics
3 common reasons to use purge systems
They allow electrical enclosures to be installed in hazardous areas without the need for explosion proof enclosures.
They recycle the air inside of an enclosure, reducing the internal temperature.
They help reduce the effects of corrosion on components housed within the enclosure.
How does a purge system work?
Purge systems use incoming air from a supply line, solenoid valves, pressure gauges and pumps, to constantly maintain a positive pressure inside an enclosure. This prevents any flammable gases from entering the enclosure potentially causing an ignition event to occur. By maintaining a positive pressure within the enclosure, moisture and corrosive gases are also prevented from entering the enclosure and damaging components. Most purge systems will ensure that the air inside the enclosure is recycled a certain amount of times within a given time period. This air recycle function assists in maintaining a cooler temperature within the enclosure.
