BAND HEATERS Ceramic band heaters transmit heat through both conduction and radiation. The element winding is designed to run at maximum temperature and heat the ceramic blocks to the point at which they radiate energy into the barrel as well as conduct energy by being in contact with the barrel. A drum heater – also called band heater, barrel heater, container heater or canister heater-is used to reduce viscosity of liquids and gels by heating in order to fill, pump or bottle the respective liquid or to prevent liquids from freezing inside the drum. The high quality strip and tubular heating elements that are used in making OMEGALUX band heaters are secured to the cylindrical surface being heated by a heavy duty non-slipping clamping band. This assures positive and constant pressure to the heating elements, thereby maximizing heat transfer to the work area.
