MIAL heating cable is designed for heating pipelines, tanks and process equipment in the

temperature range from -60 to +800 °C, including aggressive and explosive areas.

MIAL cables can be used in oil refining, chemical, pharmaceutical, food and other industries.

If the thermal output of the electric heating system is correctly calculated, the cable can be used in a broad temperature range.

Shipped as cable or ready-made heating units. Heating unit consists of a heating cable, couplings, cold cable inserts, cable glands and flexible installation wires.

Due to the high thermal stability of the magnesium oxide insulation, the MIAL cable can safely operate at ambient temperatures up to +800 °C.

MIAL cable has excellent mechanical strength and high corrosion resistance, can operate in aggressive environments and hazardous areas.

MIAL cable is fire-resistant and safe to operate.
