Thermon VSX Heat Tracing Cable

Heat Tracing Cable


VSX - 15, 32, 48 and 64w/m

ATEX & IECEx Certified for Zone 1 & Zone 2 Hazardous Areas

Suitable for Process Temperature Maintenance

Thermon VSX heat tracing cables are self-regulating and capable of maintaining process temperatures up to 150ºC. It can also be used in areas which are subject to steam purging due it's high maximum exposure temperature of 250ºC.

Thermon VSX Heat Tracing Cable

VSX heat tracing cable is available in 4 variations providing power outputs from 15w/m up to 64w/m (at 10ºC) enabling it to be used for applications from frost protection to process temperature maintenance and will never overheat or waste energy due to it's self-regulating technology. This also means that the cable can be overlapped onto itself if required without risk.

The heat tracing cable is part of the Thermon Industrial heating range and is ideal for manufacturing factories, plant rooms, distilleries, pharmaceutical laboratories and many more and is ATEX and IECEx certified for use within potentially explosive atmospheres and hazardous areas.

Typical VSX Heat Tracing Applications Include:

  • Process Temperature Maintenance
  • Pipe Frost Protection
  • Tank Heating
  • Hopper Heating
  • Vessel Heating
  • Long Line Trace Heating
