Electrical Heat Tracing

controllers_group-ThermonCarotek is proud to be the manufacturing representative and distributor for Thermon Heat Tracing. With Thermon's complete line of electric heat tracing products, Carotek can offer a solution for all your heat tracing needs whatever the application; freeze protection, high temperature maintenance or critical process control for analyzer lines and tank heating applications.

Electric heat trace controls systems vary based on design parameters specific to particular application requirements. Thermon is the manufacturer of the widest variety of electric heat trace wire cables and control systems in the world.

Request Heat Trace Audit for Winter Protection

Protect your plant from costly down time, decreased production, and water damage caused by frozen pipes, instruments and vessels this winter.  Carotek and our partner, Thermon, can conduct a complete heat trace audit and recommend the options for freeze protection solutions, for both hazardous and non-hazardous areas. Contact us today.

The audit will factor in key considerations to ensure long term reliability of your electric tracing systems.  We will help ensure quality and appropriate products are selected that are suitable for lifetime of plant operation (minimum 20 years) in accordance with IEEE benchmark testing. 

We can provide survey services and detailed reports on the condition of your existing electric heat tracing systems.  Thermon offers detailed designs with ‘as built’ documentation on any new systems installed.  Thermon has over 10 years experience in the installation of complex electric tracing projects.  We can help maintain your system to ensure trouble free operation and avoid major upgrades later.

ThermonProductsHeat Tracing Cable Types

Self-regulating heat trace cables are designed to provide freeze protection or process temperature maintenance to piping. These cables can be used on metal or plastic piping, tanks and equipment.

Power-Limiting Heat Trace Cables are designed for process temperature maintenance or freeze protection. Power-limiting cables are specifically used for process temperature maintenance for high temperatures or freeze protection where there is a high temperature exposure factor.

Constant Watt Heat Trace Cables are designed to provide freeze protection or process temperature maintenance. The parallel resistance configuration allows the cable to be cut to length and termination in the field with easy to use Thermon supplied kits.

Thermon also manufactures heat trace cables used in applications for long line temperature maintenance or freeze protection and high temperature maintenance, high temperature exposure and/or high watt density applications that exceed the limitation of thermoplastic insulated cables.


Steam Tracing provides solutions that range from freeze protection to maintaining temperatures close to that of steam itself. Heat Transfer compounds create an efficient thermal bond between a steam or electric heater and process pipes or equipment.

Heat Transfer compounds create an efficient thermal bond between a steam or electric heater and process pipes or equipment.


Instrument Tubing Bundles are a cost effective way to provide tubing that requires heat trace and insulation. These pre-Insulated bundles provide reliable process temperature maintenance in a variety of analytical and process instrumentation applications.
