Trace Heating

mineral insulated cable

Chromalox MI mineral insulated trace heating cables provide frost protection and temperature maintenance in a variety of demanding applications. With hazardous area certifications from ATEX, IECEx, CSA and FM, the Chromalox MI enables excellent resistance in many corrosive environments. 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.
