'''Heating Coils''' or Coil heaters and cable heaters are heating elements formed from straight, uncoiled segments of heating cable. | |||
Coil heaters and cable heaters are made from several different types of materials and typically include insulation. Sleeve, sheath, and jacket materials include aluminum, brass, copper, iron, nickel alloy, steel, and stainless steel. Insulation materials include ceramics, mica, minerals, and fiberglass. Mica is highly resistant to acids while fiberglass is impervious to many caustics. Some coil heaters and cable heaters may be fully or partially immersed in heated substances, while others are corrosion-resistant or suitable for cryogenic use. Clamping straps provide additional protection for coils and connections. | |||
There are many applications for coil heaters and cable heaters. For example, larger devices are used in plastic injection molding machines, holding tanks, metallurgical analyzers, and pulp and paper processing. Coil heaters and cable heaters are also used in blow molding machines, oil reclamation equipment, and food and candy extruders. Smaller, localized devices are used in labeling, bag sealing, hot stamping, and packaging equipment. | |||
