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.
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 30 mA is
recommended to minimize nuisance tripping.

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.
