FM Approved MI Heating Cable
Mineral insulated, Nickel Chrome alloy sheathed heating cables have found a niche in the electric surface heating industry. These robust heaters have earned a reputation for strength and durability.
The heater is comprised of three components:
Copper sheathed cables are used for general environments where corrosion and high temperatures will not be present. The cables should not be used above a working temperature of 300 F or where a exposure temperature of more than 400 F is required.
Nickel Chrome alloy cables are able to withstand 1250 F energized and can maintain temperatures up to 800 F. The base sheath is unaffected by a wide range of aggressive alkalis and acids, thus making the cable ideal for projects in chemical plants, refineries, utilities, etc.
Using single or three phase supplies and carefully selecting the correct cable can make heating circuits for voltages up to 600 volts. Hotfoil offers a design service to clients for all heating cables and ancillary components.
Both single and two core heating cables are available and thorough consideration is given to each design to give the best system possible.
On all M.I. systems it is recommended that metal tape or foil be applied over the heating cables prior to installing the thermal insulation. This will avoid any thermal insulation becoming trapped between the cable and the object being heated.
