The Electrothermal HT7 and HT9 Glass Fibre Tapes are flexible heaters that are ideal for heating columns, pipes, valves and transfer lines, especially when these applications need to be observed.They can be applied to metal pipes as well as glassware. Both HT7 and HT9 Series Glass Fibre Tapes have an element wound on a glass fibre core and covered in braided glass fibre outer sheath; the HT9 series additionally has a braided earth (ground) wire beneath the outer sheath. They are available in different lengths to accommodate a broad range of temperatures with a maximum element temperature of up to 450°C. As with all the tapes and cords, the use of an energy or temperature controller is recommended
