Heating Coils
Heating coils are straight heating cables that have been formed into set patterns. The formation of patterns enhances the cable's ability to transfer heat while also increasing the cable's surface area. AC voltages are typically used to operate these heating elements.
Heating coils are available in many different shapes and sizes including square, straight, coiled, round, spiral-wound, and rectangular. Different types of materials can be used to construct heating coils, such as sheath, sleeve, iron, copper, brass, nickel alloy, steel, and aluminum. Mica, ceramics, fiberglass and minerals are some of the common materials used to insulate heating coils.
Numerous industries and products utilize heating coils on an everyday basis. Such products as metallurgical analyzers, plastic injection molding machines, holding tanks, paper processing equipment, oil reclamation equipment, blow molding machines, food extruders, packaging equipment, bag sealing machines, hot stamping equipment, and labeling machines all often contain heating coils as a heating element.
