    This single-door enclosure provides industry-leading protection for systems incorporating large components or complex mounting configurations in highly corrosive environments. The addition of 19-in. rack-mounting accessories makes these enclosures ideal for providing rugged protection for sensitive rack-mounted components in harsh industrial environments. The enclosure is typically used in food-processing plants, pharmaceutical manufacturing facilities, petrochemical plants and waste-water treatment facilities.


    These enclosures are used in harsh industrial environments to house large components such as motor starters, drives, contactors and PLCs as well as a wide range of other electrical and electric equipment. A modular interior rail system (ProLine) provides an extensive range of mounting options. Whether your application calls for rack mounting, panel mounting or grid system mounting, a combination of ProLine components can deliver the right solution for ultimate equipment mounting flexibility and convenience. Three-point latching and sealing provide industry-leading protection from dust, oil and water. The FS66S enclosures are used extensively in oil and gas, water/wastewater, petrochemical and power plant environments and offer a perfect solution to outdoor DCS applications. Four styles are available to provide maximum flexibility: One-Door Single-Access Enclosures (single door on front); One-Door Dual-Access Enclosures (single door on front and rear); Two-Door Single-Access Enclosures (doors close on a removable center-post); and Two-Door Dual-Access Enclosures (doors close on a removable center-post on front and rear). Each style is also offered in 304 or 316L stainless steel, and can be manufactured as standard duty (14 gauge) and heavy duty (12 gauge).
