Bartec the premier heat trace manufacturer in europe who is now entering the us market also offers a medium temperature aht cable that is capable of reaching 797f. Mineral insulated cables ran at high current densities to produce heat and control equipment was adapted from other applications. Monitor wire braid and jacket maximum maintenance temperature. Sum the amount of cable needed for each type of roof feature to determine the total cable length.

The first step in designing a heat trace system is to determine the heat loss from each pipe or tank to be traced. This aht cable is cut to length in the field and offers a flexible aluminum jacketed design. Then fol low the steps below to determine the heat loss. While a temperature controller is recommended for all heat tracing applications in this case it should be considered essential.

A length with a denotes that the power delivered by the cable is more than enough to bring the pipe to your chosen setpoint. The mi cable is made to order and cannot be cut to length in the field. Mineral insulated resistance heating cable was introduced in the 1950s and parallel type heating cables that could be cut to length in the field became. 150 f 65 c max intermittent exposure.
