Our most popular product is our cartridge heater.
We make low to medium and high watt density cartridge heaters. Cartridge heaters provide localized heat to restricted work areas requiring close thermal control. Dies, platens and a variety of other types of processing equipment are efficiently heated. Closely controlled work temperatures up to 1400° F (760° C) are obtained by a combination of heater location and proper wattage output.
Immersion heaters are ideally suited for heating various liquids. They are available in various sheath materials and watt densities tailored for your specific applications. Units may be supplied for single, three-phase or three heat operation. The lead end of the unit may be sealed for extreme environmental conditions.
Stainless steel strip & Finned strip heaters provide clean, dependable heat with sheath temperatures up to 1200° F(650° C) and watt densities up to 40 watts per square inch. Finned strip heaters are available with aluminum or stainless steel fins. Mica insulated strip heaters are also available in various sizes.
Tubular & Finned Tubular Heaters have built-in resistance to impact, vibration, corrosion, and temperature extremes. The heater is swaged, reducing the diameter of the sheath and compacting the insulation. This insures rapid heat transfer and holds the coil in position for forming. Many diameters, sheath materials and configurations are available. are a self-contained one-piece assembly.
Foil and Glassrope® heaters area self- contained one-piece assembly. A resistance element is laminated between two layers of aluminum foil. This heater is ideally suited for area and surface heating applications. Operating temperatures up to 300° F (150° C). Sizes range from 1.25” to 60” wide with lengths of 4” and up. Glasrope® heaters are flexible heaters available in various lengths, sheath materials and terminations. Operating temperatures up to 900° F (485° C).
Air process heaters will provide hot air and gas up to 1500° F (815° C) with infinite control by varying the voltage and airflow.
Air heaters are available with various male and female fittings, hose adaptors (entry only) and flanges. We can also provide temperature sensing control.
Crankcase heaters are used to overcome the problem of migration and condensation of refrigerant in the crankcases of compressors used in air conditioning and heat pump systems. They are designed to keep the crankcase oil at a temperature higher than the coldest part
of the system to prevent migration. They are constructed of the highest quality corrosion resistance materials and sealed against moisture.
Backer Hotwatt, made in USA, was established in 1952 and has maintained leadership in manufacturing resistance heating elements for over 65 years. We supply customized and stock electric heaters. We are dedicated to the design and manufacturing of resistance heating elements for a variety of OEM, industrial, medical, commercial, packaging, instrumentation, aviation, transportation, refrigeration/ air conditioning, and military applications. In addition, we can supply compatible accessory items, which enable us to offer a complete heater system.
