Chromalox MI mineral insulated heating cables provide rugged and reliable heat tracing for a variety of demanding applications. The high nickel alloy sheath, magnesium oxide dielectric insulation and resistance wire construction allow the tracing of equipment up to 1100°F maintenance temperatures and excellent resistance to many corrosive environments. At lower temperatures, watt densities of up to 50 W/Ft can be designed. Please contact factory for cable maintenance temperature above 400°F.

MI Corrosion Selection Guide

  Moisture   Yes
   Aqueous Solutions of Inorganic Compounds   No
   Liquids Organic Chemicals Acids or Bases   Yes
  Acids or Bases   No
C - Tin-Plated copper metallic braid for additional protection and ground path
CT - Fluoropolymer corrosion resistant overjacket over braid for hostile/corrosive environments
CR- TPR overjacket over braid for protection against certain inorganic chemical solutions

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.
