Enclosure (ExE)

Enclosures: Our explosion-proof enclosures are meticulously designed to house electrical and electronic equipment in hazardous environments. These enclosures are crafted to prevent any internal explosion from igniting the surrounding atmosphere, ensuring maximum safety in industries such as oil and gas, chemical processing, and mining.

Hazardous Area Electrical Enclosures

KLEEV enclosures stainless steel enclosures are certified for use in: Zone 1 & Zone 2 (Gas) and Zone 21 & Zone 22 (Dust) environments. Available as empty enclosures, terminal boxes, or local control panels (LCPs), they provide certified protection for electrical, instrumentation, and control equipment installed in explosive atmospheres.
