Square and Rectangular
Square and Rectangular Cartridge Heater is designed to distribute maximum heat within a desired area. Because they are completely enclosed, square units will furnish more usable heat for a given wattage than a comparable strip heater attached to the exterior of a mold, platen, or other equipment. The units are inserted in a milled slot, permitting greater lengths than would be feasible with a drilled or reamed hole. Close dimensional tolerances are held to permit intimate fit for best heat transfer to surrounding medium. Heating elements arranged just beneath outside surface for maximum heat transfer, minimum wire temperature, and faster heating. Maximum surface temperatures up to 1200°F. Designations are etched on the sheath to preserve accurate shape. Series 300 stainless steel sheath for non-oxidizing, stable service in cavities machined for them. Element wire situated in close proximity to outside surface for maximum heat transfer, minimum wire temperature, and faster heating. Magnesium oxide packing. Ceramic element support. Teflon insulated leads: 1/4" square. Fiberglass insulated leads: 3/8" to 1/2" square, 1/4" x 5/8" and 1/4" x 1" rectangular.
