Thermon HTEK

Series constant watt heating cable Thermon HTEK

Thermon HTEKHigh performance HTEK series resistance constant watt heating cables are used for long line temperature maintenance or freeze protection where circuit lengths exceed the limitations of parallel resistance heating cables and high maintain temperatures or high temperature exposure is required. Circuit lengths up to 12,000 feet (3,658 m) can be energized from a single power supply point.

The series circuitry of HTEK provides consistent power output along the entire length of the cable with no voltage drop concerns associated with parallel tracer constructions.

HTEK cables are approved for use in ordinary (non-classified) and hazardous (classified) areas.

Features of Thermon HTEK

  • Long line freeze protection
  • Long line process temperature maintenance
  • No steam clean
  • Certified for use in ordinary (nonclassified) areas and in potentially explosive atmospheres

Construction of Thermon HTEK

Конструкция Thermon HTEK 1. Heating conductors (2 or 3)
2. Fluoropolymer dielectric Insulation over fiberglass composite
3. Fluoropolymer pairing jacket
4. Nickel-plated copper braid
5. Fluoropolymer overjacket provides additional protection for cable and braid where exposure to chemicals or corrosives is expected

Ratings of Thermon HTEK

  • Rated voltage: for operation up to 600 Vac
  • Max. maintenance temperature: 400°F (204°C)
  • Max. continuous exposure temperature
    Power-off : 500°F (260°C)
  • Minimum installation temperature: - 60°F (- 51°C)
  • Minimum bend radius:
    5°F (-15°C): 0.875” (22mm)
    - 76°F (- 60°C): 1.25” (32 mm)

Circuit breaker sizing

The maximum circuit length is a function of cable resistance, circuit length and operating voltage. Circuit length and/or breaker sizing should be based on the National Electrical Code, Canadian Electrical Code or any other applicable code. For information on design and performance on other voltages, contact Thermon.The National Electrical Code and Canadian Electrical Code require ground-fault protection of equipment for each branch circuit supplying electric heating equipment. Check local codes for ground-fault protection requirements.

Terminations and splices

Prior to connection to power, HTEK heating cables should be terminated using Terminator DP-M, ZP-M or with an appropriate nonheating “cold lead” and a “hot-end” termination. To facilitate ease of installation and accommodate standard shipping lengths, in-line splices may also be required. These connections/terminations are available as factory fabricated assemblies or as field fabricated kits
