Tubular Heaters are the most versatile and widely used source of heat as they are easy to handle and have a long life expectancy due to its ruggedness. Some of the advantages are that they can be virtually formed into any shapes and brazed or welded to any metal surface. In this heaters the NiCr resistance wire is helically wounded and evenly stretched and inserted into SS or Incoloy Tube which is insulated using MgO powder. The Tube is then swagged and annealed thus emitting heat excelantly. Then it can be kept straight or formed in any shape like Ring, spiral bend, helical, or customised into any shape as per the requirements.The terminal can be designed stud or wire type.They can be customised in any variety of sizes.
They are widely used in Packing, Hot Plates, Moulding, Forced Air Heating, Heating Liquids, Radiant heating etc.
