Finned and Non-Finned Ceramic Insulated Strip Heaters

Finned and non-finned ceramic insulated strip heaters are durable high-temperature electric heaters designed for industrial process heating applications requiring efficient surface heat transfer, long service life, and uniform temperature distribution. These heaters are commonly used on tanks, dies, molds, ovens, ducting, platen equipment, and machinery surfaces where reliable indirect or contact heating is required. Ceramic insulated strip heaters are ideal for continuous-duty applications operating at elevated temperatures where mica insulated heaters may not be suitable.

Ceramic insulated strip heaters are typically constructed using helically wound nickel-chromium resistance wire precisely embedded within interlocking high-temperature ceramic insulators. The heating assembly is enclosed within a stainless steel or aluminized steel sheath for excellent mechanical strength and corrosion resistance. Non-finned ceramic strip heaters provide direct conductive heat transfer to flat surfaces and machinery components, while finned ceramic strip heaters incorporate integrated metal fins that dramatically increase surface area for improved convective air heating efficiency in open-air applications.

These industrial strip heaters are available in multiple constructions including straight strip heaters, finned air-heating strip heaters, curved or formed strip heaters, high watt density designs, moisture-resistant constructions, and custom-engineered configurations with various mounting holes, terminal boxes, lead exits, and temperature sensing options such as thermocouples or RTDs.

Top applications include packaging machinery, plastics processing equipment, drying ovens, hot air ducts, food processing equipment, semiconductor equipment, pharmaceutical machinery, laboratory equipment, heat sealing systems, and industrial air heating systems. Common industries include plastics, packaging, food processing, chemical processing, automotive, aerospace, medical manufacturing, electronics, and industrial OEM equipment manufacturing.

Major benefits of ceramic insulated strip heaters include higher operating temperatures compared to mica heaters, superior durability, excellent thermal efficiency, fast heat-up capability, long operational life, reduced maintenance requirements, improved heat distribution, and the ability to withstand demanding industrial environments. Finned ceramic strip heaters additionally provide highly efficient air heating performance for convection heating applications where rapid heat transfer to moving air is required.

Product Description

The Finned Strip Heaters basic design consists of a helically wound resistance coil placed in a specially designed ceramic insulator. The resistance coil is mechanically connected to screw terminal for positive connection. Stainless steel rectangular tubing is used to house the heater assembly. All remaining voids are filled with high purity magnesium oxide to increase thermal conductivity and dielectric strength. With channel/strip heaters the fins are used as they improve heat transfer in free or forced air heating applications. Ceramic-insulated finned strip heaters are ideal for applications including ovens, load banks, duct heating, drying ovens and food warmers.
