Tubular heaters are a type of electric heating element commonly used for various industrial and commercial applications. They consist of a metallic sheath typically made of stainless steel or other heat-resistant materials, enclosing a heating coil or resistance wire. The sheath provides protection and allows the heater to be installed in various environments.
Types of Tubular Air Heaters:-
- With Fins
- Without Fins
Specifications
- Tubular heaters are typically made of a metal sheath, which can be straight or bent into various shapes, such as U-shape, W-shape, or spiral. The heating coil or resistance wire is inserted into the sheath and tightly packed with magnesium oxide (MgO) powder for efficient heat transfer.
- The choice of sheath material depends on the application requirements. Stainless steel is commonly used due to its corrosion resistance and ability to withstand high temperatures. Other materials such as copper, Incoloy, and titanium may be used for specific purposes.
- Tubular heaters come in a wide range of wattages and voltages to suit different heating requirements. The wattage determines the amount of heat generated by the heater, while the voltage determines the power supply needed.
- Tubular heaters can be used with temperature control devices such as thermostats, thermocouples, or temperature controllers. These devices help maintain the desired temperature by turning the heater on or off based on the temperature readings.
