• Hot watt high density cartridge heaters have superior design compared to conventional cartridge heaters. Coil made from top quality nickel chromium wire is precisely placed inside the tube and the tube is filled with high purity magnesium oxide powder. This unit is then swaged to compact the insulation. This compacting of the insulation results in faster heat transfer and heater can withstand normal shocks and vibrations. S.S. Or incoloy is used as the standard sheath material. These heaters are also available with `built in` thermocouples ( j or k type ), which are useful where it is not possible to put a sensor. Sizes available are 5/16 " or 8 mm onwards in diameter and 3 " or 75 mm onwards in the length. Wattages available are up to 100 watts per sq. Inch of sheath area. The most important thing to remember about the installation of the cartridge heater is that the cartridge should be close fit in the hole into which it is inserted. This results in faster heat transfer to the surrounding material and aids in keeping the element as cool as possible for long life. The holes should always finish- ream drilled to ensure uniform metal to metal contact. The receptable hole should be free from oil, dust, rust etc. Before cartridge heater installation to avoid contamination and short heater life. apart from this finest quality product, hot watt industries is also interested in supplying other good qualities products like long life `u` shape air & finned air heaters with m.
