Thermal-Flex MultiTrace constant wattage heating cables are designed to deliver uniform power output while providing freeze protection or viscosity maintenance for piping, valves, pumps, tanks, and vessels, as well as freezer floors and foundations and similar heating applications. Constant wattage heating cables are also commonly used to prevent freezing of drain lines and air conditioning lines located in most industrial environments. Constant wattage heating cables are essential to the frost protection and deicing of electrified power rails at many railroad transit companies and other types of people mover systems in cold northern climates.
Thermal-Flex MultiTrace heating cables are constructed of two parallel stranded, plated, copper buss wires with spiral-wound zones of nickel chromium heating wire. Alternating buss contact at designated intervals forms a link of parallel zones of equal resistance producing constant power output in each zone. Cable jacket options such as metallic overbraids and Teflon® overjackets are available.
