Chromalox CZH Cable is a multi-purpose heating cable designed for commercial pipe tracing, embedded floor warming, and frost heave prevention. Chromalox’s CZH Cable is constructed of a parallel heating core that produces uniform thermal output over its entire length. It can be easily cut to length, spliced, tee to more easily follow piping networks.

Chromalox’s CZH Heating Cable can be placed in conduit embedded in concrete to prevent frost heave or placed onto concrete slabs for supplemental comfort heat. Chromalox’s CZH cable can even be placed inside of conduit for applications making replacement of the heating cable possible. Chromalox’s CZH is truly a versatile heating cable solution.

WARNING — A ground fault protection device is required by NEC to minimize the danger of fire if the heating cable is damaged or improperly installed. A minimum trip level of 30mA is recommended to minimize nuisance tripping.

 

  • Durable, non-aging fluoropolymer jacket ensures long service life and can be used in some hostile environments.
  • Flexible, easy to install on most equipment and delivers long-term reliable performance.
  • Accurate temperature, reliable electric heat that can be consistently controlled and easily monitored.
  • Parallel circuitry allows cut-to-length.
  • Low profile, uses standard size thermal insulation on piping and process equipment.

CT - Fluoropolymer corrosion resistant overjacket over braid for hostile/corrosive environments

This is a recommendation guide. Chromalox cannot warrant any Electric Heat Trace against failure by sheath degradation if such failure is the result of operating conditions beyond the control of the heater manufacturer. It is the responsibility of the purchaser to make the ultimate choice of sheath material based on knowledge of the chemical composition of the corrosive solution, character of materials entering the solution, and controls which maintains the process.
