Tubular Heater
Tubular Heater
Nowadays, every business uses heating applications in one way or another. Our daily lives are significantly impacted by the heating. Concerns about the efficiency of many of the heating solutions being utilized, as well as their effects on the environment and safety, are becoming more and more prevalent as the reliance on heating applications increases. Many of the other typical methods produce a lot of carbon dioxide and other pollutants that pollute the environment, even if some of the systems are susceptible to fire incidents.
One of the greatest choices for the current world is a tubular electric heater, which is the safest method of heating any liquid or surface without releasing any harmful gases.
Typically, a resistivity coil enclosed in a metal tube filled with insulating materials like magnesium oxide is used to create tubular heaters. No electric shock is transmitted to the exterior thanks to the heating coil, which is positioned in the middle with uniform pitches and is isolated from the outer metal sheath by compacted magnesium oxide. All of the generated heat energy is simultaneously transmitted to the process via the external body. Thus, the heater is considered to be among the safest and most effective heating options.-
- Nickel Chromium Resistance was uniformly coiled wire is stretched through the active length of the element.
- Magnesium oxide High purity magnesium Oxide power is filled between the coil and outer tube in an automated filling station to ensure the right insulation, conduction as well as compactness
- Outer sheath Tube (welded or seamless) which acts as outer protection for the Heating Element. The selection of the outer tubes depends on various factors such as temperature, pressure, fluid to be heated, etc.
- Terminal pins Also known as terminal pins are extended ends of the heating elements. The SS rods of a specific diameter is fusion welded to the coils at both ends. The length of the rod depends on the non-heating length required for any application and installation.
- End Sealing Sealing is done using the combination of Ceramic beads, soft seals & sealants. The sealing ensures that no moisture from the atmosphere enters the heating element and keeps it dry.
