band heater

Tanks requiring industrial tank heaters can utilize indirect heating with band heaters or, they can use direct heating that typically uses some form of immersion heating.

Indirect Heating
WATTCO Band heaters can be found in several types of dimension, wattage, voltages and material. Mica band heaters are an inexpensive industrial heating solution that surrounds pipes and tubes that require external indirect heating. Pipe heating, drum heating, barrel heating normally used for oils, lubricants or any other circular applications. Band heaters use electric heating elements (NiCr wire) to heat-up the external surface of drums or pipes for a gradual heat transfer. Band heating is an indirect form of industrial heating and offers safety when heating volatile and explosive substances as well as pipes or containers that cannot otherwise be heated using direct heating methods. Industrial band heaters can be made with NEMA 1 terminal boxes or NEMA 4 moisture resistant terminal boxes that protect terminations and have the option of a thermostat or thermocouple digital temperature controllers to help control and regulate an applied heat. Insulation is also required to help direct the heat to your application rather than experience heat loss, and slow heat-up time.

Band heaters from WATTCO are the ideal solution for high watt densities and high operating temperature applications, especially for the plastics industry. The various types of band heaters available at WATTCO include mica insulated band heaters and ceramic band heaters.
