Factory built-in options and a selection of electrical enclosures are also available for added convenience and safety. The flexibility of the XEC1 ProTektor design allows, at the time of factory ordering, for users to request that their electrical enclosure, plus any built-in options selected, be mounted on the right side (standard) or left side (option) of the sloped-top cabinet. The XEC1 ProTektor series of industrial-grade convection air heaters are engineered to meet the most demanding requirements of industrial environments. The harsh operating conditions require heating equipment that is safe, reliable, and available when you need it. XEC1 convection heaters are designed for maximum heating performance and to provide primary or supplementary heating of people or equipment in areas that are classified as hazardous gas atmosphere locations. XEC1 convection air heaters are suitable for a wide variety of applications that include, but are not limited to, petroleum refineries, gasoline storage and dispensing areas, hydrogen atmospheres, oil & gas wellhead buildings, petrochemical plants, sewage or wastewater treatment plants, battery storage areas, dry cleaning plants and hazardous material storage buildings. The versatile XEC1 ProTektor heater incorporates high quality Incoloy 800 tubular elements, an aluminum tube assembly with pressed radial-embossed aluminum plate fins, and O-rings on enclosures for IP66 & Type 4 ingress protection. The cabinet construction consists of a 14 GA galvanized steel back panel and 14 GA carbon steel with epoxy/polyester powder-coating on the front and side cabinet panels for added protection from corrosive atmospheres. With no exposed copper or brass they are also suitable for H²S environments. Mounting brackets are fabricated from 14 GA galvanized steel.
