Self-Regulating Heating Cable HTSX THERMON

Self-Regulating Heating Cable HTSX THERMON

Self-Regulating Heating Cable HTSX THERMON




HTSX self-regulating heating cables

are designed to provide freeze protection or process temperature maintenance to metallic and nonmetallic piping, tanks and equipment. The heat output of HTSX cable varies in response to the surrounding conditions along the entire length of a circuit. Whenever the heat loss of the insulated pipe, tank or equipment increases (as ambient temperature drops), the heat output of the cable increases. Conversely, when the heat loss decreases (as the ambient temperature rises or product flows), the cable reacts by reducing its heat output. This self-regulating feature allows HTSX to be overlapped without temperature upset damage to the cable. HTSX cables are certified for use in ordinary (nonclassified) areas and in potentially explosive atmospheres in accordance with the ATEX Directive and the IECEx Scheme.2

provides additional protection to cable and braid where
exposure to organic chemicals or corrosives is expected.
Thermon offers system accessories designed specifically
for rapid, trouble-free installation of Thermon heating
All cables require a connection kit to comply with approval
requirements. Information on accessories to complete
a heater circuit installation can be found in the “Heating
Cable Systems Accessories” product specification sheet
(Form TEP0010).
