Heating jackets use a heating element to maintain the correct temperature. This configuration can use a multi-stranded tape-type heating element or a self-regulating cable-type element to achieve the desired temperatures to ensure that gases or fluids stay at the proper temperature. Insulator jackets, unlike heating jackets, do not use a heating element to control the temperature. Instead, the insulation itself works to maintain the temperature of whatever object or fluid the jacket surrounds.
