Description
Thermon VSX-HT™ Self-Regulating Heating Cable
High-Temperature Self-Regulating Heat Trace Cable for Industrial Applications
Thermon VSX-HT™ is a premium self-regulating electric heat tracing cable engineered for high-temperature process maintenance and freeze protection in demanding industrial environments. Designed with advanced fluoropolymer insulation and a self-regulating heating matrix, VSX-HT automatically adjusts its power output according to the surrounding temperature, improving energy efficiency while minimizing the risk of overheating. It is ideal for applications where elevated maintenance temperatures and intermittent high-temperature exposure are required.
Key Features
- Self-regulating technology automatically adjusts heat output along the entire cable length.
- Maintains process temperatures up to 200°C (392°F).
- Withstands intermittent exposure temperatures up to 250°C (482°F).
- Suitable for both freeze protection and high-temperature process maintenance.
- Can be cut to length on-site without affecting performance.
- Safe for overlapping during installation without burn-out under normal operating conditions.
- Heavy-duty fluoropolymer jacket provides excellent resistance to chemicals, moisture, and mechanical damage.
- Designed for installation in both ordinary industrial areas and hazardous locations.
Construction
VSX-HT features a rugged multilayer construction for maximum reliability:
- Nickel-plated copper bus wires
- Self-regulating conductive heating matrix
- Fluoropolymer dielectric insulation
- Nickel-plated copper braid for grounding and mechanical protection
- Fluoropolymer overjacket for superior chemical and corrosion resistance
