Creating a niche of Tubular Air Heaters such as Single-Pass Tubular Heater, Finned Tubular Heaters, Custom Built Heaters, Two-Pass Construction Tubular Heaters, Air Duct Heaters, Tubular Heating Elements and many more items at its best, with utmost quality.
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.
Finned tubular heating elements are of the type where the surface area is enlarged by a strip in order to heat gases. At high power the surface temperature is small and the heating element is short. MATRUSREE’s Finned Tubular Heaters are manufactured with the same rugged construction as the standard Tubular Heaters except a MILD STEEL ELECTROPLATED or a corrugated 304 STAINLESS STEEL FIN is helically wound on Heater Tube diameter (304 stainless steel) element. To insure a permanent bond, each end of the fin is fully brazed to the Heater sheath, for optimum heat dissipation and efficiency, as Brazed fins transfer heat at about double the efficiency of unbrazed designs. These heaters are ideal for heating air and select gases in forced and natural convection applications.
Custom Built Heaters offered comprise standard tubular Heating elements that can be made available in different bending choices and configuration options to pick from. With maximum Sheath Temperature of 620°C and Watt density of up to 25 w/in², these heaters can be provided with different metal based heating elements like Copper, SS304, SS316, SS316L, Teflon coated sheath material and others as per the specific demands of the customers. Further, these custom built heaters can also be provided in explosion proof/resistant terminal enclosure option. These heaters can be provided with different mounting support including bracket mounting, clamping, thread nipple fitting and other options.
For applications requiring both terminations at the same end, either a U-bent or a two-pass element may be used. Two-pass elements, as shown in the cutaway view, have a U-bent coil inside the sheath and two leads or terminals at one end. Welding or silver soldering seals the opposite end. These elements are available in straight lengths, either finned or unfinned. They can be permanently mounted with a variety of factory-furnished mounting methods. By contrast, standard elements in straight lengths must have a flexible electrical connection at one end to allow for thermal expansion.
Capable of withstanding much higher operating temperatures than conventional tubular heaters.Avaliable in (15.8mm), 0.669" (17mm), 0.748" (19mm) element diameter.Can be immersed in liquids, for Liquid Heating Applications. Two-Pass Heating Elements can be finned.Several wattage and voltage combinations are available.
Inserted in machined holes to heat dies and platens. Multi zone heating. High temperature furnaces. Simulated fuel elements for nuclear reactors. Pressurizer heaters. Dry out heaters in large generators.
MATRUSREE’s Duct Heaters are constructed out of variety of tubular Heater combinations & inner mountings. While Duct heaters are easily adaptable to many non-pressurized, air-heating systems, they also offer several advantages over gas or oil fired and open coil electric heating units.
Matrusree electro heats designs and manufactures industrial electric tubular heaters that set the industry standard for excellence. The most versatile of all electric heating elements, the tubular heaters are capable of being formed into virtually any configuration.
Three basic tubular air heaters constructions are illustrated here.
Tubular Heaters offered can be offered by us in different choices including casted tubular heaters, duct heaters, finned tubular heaters and others as preferred and demanded by the customers. Featuring quality construction standards and providing for durable usage, these heaters find suitability for different industries. Some of the parameters these heaters can be provided in include different tube diameters, tube sheath materials for high temperature application like SS304, SS316, SS316L and others. Further, the choice of different rating options and termination options make these suitable for industrial, commercial and scientific applications.
We offer a variety of basic types of tubular heaters:
Our commercial heating element converts electricity into heat through the process of Joule heating. Electrical current running through the element encounters resistance, resulting in heating of the element. We use high quality nichrome wire or ribbon as the conductor because nichrome is an ideal material, as it is inexpensive, has relatively high resistance, and does not break down or oxidize in air in its useful temperature range.
We are manufacturers of a complete line of electric duct heaters with various physical sizes and kw/btu/h outputs. They mainly are used to boost air temperature for any forced air system.
