Self-regulating electrical trace heating cables help pipes keep warm in very cold weather to prevent them from freezing. Self-regulating electric heating cables have a heat output that depends on the temperature: the highly engineered resistive core reduces heat output as temperature rises, and vice-versa. These cables are available with either tinned-copper or stainless-steel braid as a protection against mechanical shocks. Electric trace heating cables are widely used in many industries. Typical applications include: defrosting; reaching and maintaining temperature in pipelines; keeping temperature constant in chemical processes; protecting roofs, etc.
Long-term reliability and functionality of such devices is extremely important to consider, as such electrical heating cables are more than often crucial to successful operation, to smooth process start-up or changeover. The inconvenience caused by repairing or replacing heating materials that have failed can be quite significant.
The below range of self-regulating electrical trace heating cables is designed to provide freeze protection and temperature maintenance to metallic and nonmetallic pipes, tanks and equipment.
Self-regulating heating cables of the FST range:
Usage: protecting against freezing or maintaining moderate temperatures.
Types: FST/T, FST/I, FST/TP and FST/TF comply with the technical evaluation document issued by the CSTB.
Protection against freezing in gutters: Cable FST/TP/30 is recommended..
Environments with an explosion risk: Cables of type FST/T, FST/I, FST/TP and FST/TF can be used, with the appropriate accessories..
Using a control device is recommended to ensure a long service life.
