Tubular Heating Elements

Tubular heating elements are highly versatile and efficient components designed for various industrial heating applications. Made from Nickel-Chrome wire, which is helically wound, the coil is encased in a SS 304 sheath. The space between the coil and the tube is filled with Magnesium Oxide (MgO), which enhances thermal conductivity, dielectric strength, and extends the heater’s lifespan.

Finned Tubular Heaters

Finned heaters are designed for fast air heating, using fins (SS or MS) mounted onto the tubular elements to increase surface area and enhance heat dissipation. They’re widely used in duct heaters and air-handling systems.

Design & Construction

Coil: The Nickel-Chrome wire is wound helically to produce high heat output.
Sheath: SS 304 stainless steel is used for durability and corrosion resistance in high-temperature environments.
Insulation: Magnesium Oxide (MgO), with a specifically selected grain size, ensures efficient heat transfer and insulation.
Compression: The tube is compressed via a swaging machine, which secures the coil in the center of the tube, ensuring uniform heat distribution.
Terminals: Stainless steel screw-type terminals securely connect the coil to the power supply, with one end of the coil welded to the screw’s inner end.
