1 American Bureau of Shipping Class I, Divisions and 2, Groups B, C and D Class II, Divisions and 2, Groups E, F and G Class I, Zones and 2, Groups IIB and H2 Applications Battery Storage Areas Chemical Plants Coal Handling Facilities Dry Cleaning Plants Gasoline Fueling/Storage Areas Grain Elevators Oil Refineries Paint Spraying/Storage Areas Petrochemical Plants Heatrex s explosion-proof convector is designed to provide a heavy duty and corrosion resistant heat source. Features include: Wide Selection of s: Four compact sizes to fit any space with ratings from 500 to 9,500 watts. Sloped Top Cabinet: Prevents objects from being set on top of the convector, which can restrict airflow and cause overheating. Single and Three-Phase: Unique design provides single and balanced three-phase loads in a single element. Gas and Dust Atmospheres: Three listings cover the entire field, two for hazardous gases and vapors and one for dust particles. Wet Locations: All unit sizes available with iridite- coated elements and powder-coated frames for NEMA wet locations. Standard Construction Features Element Grade A Nickel-Chromium heating coils are insulated with ceramics and magnesium oxide from the copper heater tube and fitted with large aluminum fins locked in place. Cabinet Heavy gauge galvanized steel cabinet is painted with a beige powder coat for durability. Cabinet should be mounted at least 6 inches (52 mm) above the floor. Factoryfurnished wall brackets make installation easy. Thermal Protection A linear limit, automatic reset thermal cutout is built into every unit. Complete Electrical Package For larger single-phase and all three-phase units, a built-on contactor and transformer option package are available. 9

2 Electrical Package Options All single-phase heaters rated over 22 amps or 277 volts and all three-phase heaters require a magnetic contactor. Some electrical combinations will also require a control transformer. To simplify field installation, these accessories are factory-mounted on the heater cabinet and factory pre-wired (not available on convectors).
