General Description
Electrothermal Heating Tapes are a range of exible resistance heater elements for use in a wide range of
commercial/industrial surface heating applications. The exible heaters are ideal for heating columns, pipes, valves
and transfer lines.
All tapes are constructed of an element covered in glass bre and a braided earth (ground) wire which is enclosed
in a glass sleeve. Lengths range from 61cm (2ft.) to 976cm (32ft.) with a linear loading of 50W/ft (164W/M).
Heating tapes are available in 120 V and 230 V versions up to 488cm (16ft.) and in 230 V only for 732cm (24ft.)
and 976cm (32ft.) lengths. Product is suitable for use in dry conditions only, is not water resistant and has a
maximum element temperature of up to 450°C and has a minimum helix diameter of 50mm (2 in.).

Important Safety Advice
Users should be aware of the following safety advice:
v SHOCK HAZARDS OR UNSAFE PRACTICES ARE DANGEROUS as they can cause severe personal injury, re
or death.
v DO NOT expose the element to liquids.
v DO NOT use combustible substances near hot objects.
v DO NOT use the equipment in hazardous atmospheres.
v DO NOT attempt to shorten, cut or allow sharp metal objects near the element.
v DO NOT operate or handle any part of the product with wet hands or use on surfaces that may become ooded.
v DO NOT overlap, kink, pinch or twist the heating tape or allow any portion to sag from the surface.
v DO NOT use worn or damaged elements or attempt to repair the element.
v NEVER move the product while still connected to the power supply.
v NEVER connect product directly to the mains supply, these are designed for use with an external temperature
controller.
v ALWAYS use with protective earth (ground) bonded installation when applied to electrically conductive vessels.
v HIGH TEMPERATURES ARE DANGEROUS as they can cause serious burns to operators and ignite
combustible material. Users should be aware of the following safety advice:
v USE CARE AND WEAR PROTECTIVE GLOVES TO PROTECT HANDS.
v NEVER lift or carry the instrument until it has been switched off and allowed to cool.
v DO NOT position the element such that it is difcult to disconnect it from the power supply.
v DO NOT leave equipment switched on and it is not recommended to leave any heating apparatus unattended
during operation.
v DO NOT apply severe physical stress or use at temperatures above the rated value.
v NOT RECOMMENDED for use on plastic pipes.
