Tubular heating element are custom designed in a various shapes to as client’s requirements for direct immersion in liquids such as water, oils, solvents and process solutions, molten materials as well as air and gases.
Tubular heaters are produced using Incoloy, stainless steel or Copper sheath materials and also there is huge variety of selection of termination styles available. Insulation of Magnesium offers greater heat transfer.
Tubular heaters can be used in any application. Straight tubular can be inserted in machined groves for conductive heat transfer and formed Tubular provides consistent heat in any type of special application. Its applications areas are: Plastic processing machineries;Engineering Industry;Packaging machinery;Shoe making machineries ;Foundry Equipment ;Radiant Surface heating ;Hot Runner Mould Systems etc.
Tubular heating element are easy to install,control and maintain, unique designer as your requirement. For corrosive enviroment, titanium material or tubular heating elements with additional teflon sleeving are available .
Tubular finned heater element is constructed like basic tubular elements with the addition of continuous spiral fins, 4-5 per inch permanently furnace brazed to the sheath. Fins greatly increase surface area and permit faster heat transfer to air, resulting in lower surface element temperatures.
