VSX self-regulating heating cables

are designed specifically for process temperature maintenance or freeze protection where high maintain temperatures or high temperature exposure is required. VSX withstands the temperature exposures associated with steam purging. The heat output of VSX cable varies in response to the surrounding temperature by reducing its thermal output with increasing temperature and can be overlapped without temperature upset damage to the cable. VSX cables are certified for use in ordinary (nonclassified) areas and in potentially explosive atomospheres in accordance with the ATEX Directive and the IEC Ex Scheme.

Basic Accessories
Thermon offers system accessories designed specifically
for rapid, trouble-free installation of Thermon heating
cables.
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 TEP0010U).
