MISS
MINERAL INSULATED HEATER CABLE

	End Termination Alloy 825 Stainless Hot/Cold Joint Compression Fitting

MI heater cables are seamless die drawn cables that are made to specified lengths to deliver high power output along the entire length of the cable. It's nichrome heating conductors are embedded in highly compressed magnesium oxide dielectric and covered with a stainless Alloy 825 sheath. The sheath is fully annealed and easily formable.
MI heater cables are factory assembled to exact specifications and cannot be cut to length in the field. Both hot and cold sections are made to customer's specifications. MI heater cables are completely submersible and resist the most aggressively corrosive environments. Alloy 825 cables are capable of withstand temperatures up to 1,000°F.

MI heater cables are suitable for use in pipe tracing applications where high temperatures are required, pad heating/snow melting; where removal of snow is needed for safety. MI heater cables are also useful in large vessel and hopper heating applications. In tank and hooper applications MI is attached to sheets of wire mesh to help diffuse the heat into the tank walls. Because MI cables are silver soldered and waterproof they are a great choice in "gut" tracing applications where the cable is inserted into a pipe.
