Vulcanic heating cables are intended for the indirect heating of liquids (water, oil, fuel, glycol, sodium hydroxide, bitumen, etc.) for maintaining temperature and frost-protection of pipework, tanks and access doors. Available from 15W/m to 60W/m up to 600°C.
Self-regulating heating cables limit, by their design, their power depending on the temperature to be maintained. They can be supplied with a stainless steel mechanical protective braid and a PTFE over-sheath against chemical attack. A temperature control sensor or thermostat is recommended to limit energy consumption.
