1 The Series convection heater, with ratings up to 5000 watts, is designed for heating spaces where explosive substances are or may be present. The is available with either C CSA US or CE/ ATEX approvals. All units can be fitted with an externally adjustable thermostat. With the, you get a safe and reliable heater with a handsome appearance and state-of-the-art design. Applications Typical applications for the include: control cabinets and small enclosures storage rooms for paints and cleaners grain elevators flour mills spray booths gas plants pump houses marine and offshore oil platforms cleaning and dyeing plants Selection of Refer to the atmospheric condition table (TABLE 2) at the beginning of this catalog for detailed selection data for the temperature code. To minimize cost and physical size of the heater, select the heater with the highest temperature code that suits the environment. In TABLE 8 and TABLE 9 a check mark (3) under the temperature code indicates that the surface temperature of the heater will not exceed the coded value listed in the atmospheric conditions table (TABLE 2) at the beginning of this catalog. Construction and Installation The XP and the explosionproof convection heaters utilize CCI Thermal s unique copper free aluminum extruded convector and patented x-max terminal housing. Large convector surface area and high mass fins ensure safe and efficient low temperature heat transfer to the environment. Convectors are black anodized to resist oxidation and maximize heat transfer. Convection Heater The x-max housing can be equipped with multiple tapped conduit entries throughout its length to facilitate installation. A track and trolley system and threaded covers at each end allow easy access to internal components. All units, except the single heat sink units, have a built-in terminal block for simplified electrical connection. The units are intended for wall or floor mounting with the heater positioned vertically as shown. Dual purpose brackets for floor or wall mounting and wire guards are supplied as standard. Special Wattage and s The following table lists the maximum design wattages for the four standard heat sink lengths and configurations. If standard units listed in TABLE 8 and TABLE 9 do not suit your application, a special unit based on TABLE 10 can be supplied (check factory).
