Once sized, the proper heat trace cables are selected with the desired wattage outputs and jacketing for the application. For lower temperatures, a highly flexible cable that appears similar to residential 12-2 wiring is used. These lower temperature cables (PSB and HSB) are capable of reaching maximum temperatures of 392F. For higher temperatures, most manufacturers offer a Mineral Insulated (MI) Cable that can exceed 1200F. Typically, the MI cable is made to order and cannot be cut-to-length in the field.
Bartec, the premier heat trace manufacturer in Europe who is now in the US market, also offers a medium temperature AHT cable that is capable of reaching 797F. This AHT cable can be cut-to-length in the field and offers a flexible aluminum jacketed design. In addition to the cables, these systems allow for customized solutions that incorporate junction boxes, thermostats, temperature controllers, light indicators, and insulation. Take a look at the images below to see the variety of options and configurations available.
