  • Tubular Heating Elements

    Highly versatile and economical Durex tubular heater elements are applied in virtually every conceivable type of heating application. They can be applied straight or bent into complex formations. They can be reliably applied to heat a multitude of liquids, gases, and solids. Tubular heaters are also used for radiant heating in open air or in vacuum atmospheres. They can be cast into, or clamped on to, metal to form heated parts. Durex Industries’ application and design engineering team are available to assist in specifying the proper heater configuration.
