Tubular Heaters

Single-Pass Tubular Heater offered come with maximum sheath temperature of 620°c and maximum watt density of up to 25 w/in². With choice of moisture resistant terminal enclosure option, these tubular heaters come casted in aluminum metal which makes these provide for broad surface coverage as well as meet the demands of uniform heating. We can also offer these in customized construction options in terms of recommended watt densities, corrosion guide, sheath temperature limitations and other parameters. Some of the applications these are used in include in Plastic industries, for high vacuum applications, for baking, for curing of plants enamels. These can also be factory formed even to small bends of one element tube diameter.
