Cartridge Heaters

This Product group is an excellent choice for direct insertion heating of platens, dies, various metal shapes and products requiring maximum amount of heat within a limited or short space. With the addition of either threaded or leak tight mountings/fittings these heaters are also an excellent choice for direct immersion into liquids.

                        Heater diameter is varying precise in designing the heaters. Units without mounting /fittings are designed to fit holes with a diameter tolerance of plus .001inch – minus.000of nominal heater diameter. For example a heater of ½”diameter (actual size 0.499 + 0.000”- 0.004”) is designed to fit a hole size of 0.500”+0.001”-0.000”. Higher rated watt densities on the heaters combined with larger hole clearances will reduces the heater life.

                        Holes preferably rimed to accept heaters should be rimed all the way through are advisable. Corrosion or scaling may make heater replacement difficult in blind holes.

                        Do not allow the heated portion of heater to operate in air or an air pocket. Do not operate any standard cartridge heater in open air.

                        Straightness or total run-out along the axis can be held to plus or minus 0.10per inch for lengths up to 4” and 0,20 per inch up to 1(One) foot. Heaters are normally flexible enough to fit into long holes.

                        Heaters installed into moving blocks or dies should have provisions for preventing the leads from being damaged from motion.
