nVent PYROTENAX HCH/HCC Mineral Insulated (MI) Trace Heating Cables


Trace heating cables for frost protection and temperature maintenance up to 200°C

PYROTENAX HCH/HCC mineral insulated (MI) series resistance trace heating cables are suitable for low temperature maintenance applications such as long pipeline heating, condensation prevention and ramp heating. The trace heating cables have a copper jacket for enhanced mechanical strength.

  • Sheath material: copper (optional HDPE over-jacket)
  • Continuous withstand temperature: 200°C (reduced to 80°C with HDPE over-jacket)

Key benefits:

  • Very robust
  • Available in a low resistance range for long circuit lengths
  • Available with HDPE or FEP over-jacket for additional corrosion protection
  • Approved for use in hazardous areas
  • Fast track service for heating units

TraceCalc Pro design software for safe design, product selection and advanced control and monitoring products complete the PYROTENAX HCH/HCC trace heating system.

PYROTENAX MI heating cables are offered as bulk cable and as pre-terminated heating units. Pre-terminated MI heating units are factory tested and can be directly installed in the field.
