Raychem HIQ Mineral Insulated (MI) Trace Heating Cables

Overview

Trace heating cables for frost protection and temperature maintenance up to 600°C

Raychem HIQ mineral insulated (MI) series resistance trace heating cables are suitable for frost protection and temperature maintenance of pipes and tanks/vessels involving temperatures up to 600°C. When the cables are terminated by laser welding, the exposure temperature can go up to 1000°C.

  • Sheath material: Inconel 600
  • Continuous exposure temperature: 700°C (dependent on the splice used)

Key benefits:

  • Very robust
  • Suitable for high power outputs and temperatures
  • Excellent corrosion resistance against organic acids, alkalis and stress corrosion cracking
  • Available with laser welded splice connections
  • 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 Raychem HIQ trace heating system.

Raychem 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.
