Short Wave IR heater transmits heat in the form of electromagnetic waves at a velocity of approximately at the speed of light. Heating is done by radiation; this eliminates loss of energy used for heating media and heat loss due to convection. Here the infrared waves penetrate the material, on which it falls and delivers the heat directly to that material and attains high temperature in shortest possible time.

Finned tubular heater are the most common type of heating elements used for heating air and other gases. The fins along the tubular length assist in even heat dissipation. All elements have mild steel fins brazed to the tubular heating element sheath. In applications where tubular heaters are exposed to forced convection, placing fins around tubular heaters increases their surface area and thus improves their heat transferring capacity. Finned tubular heaters, compared to regular tubular heaters, run at lower surface temperatures for the same watt densities when placed in identical air streams

The physical characteristics of a finned tubular heater play a major role in the effectiveness of its heat transfer. Fins are continuously spiral wound tightly onto the element surface to increase the convective surface area for air and non-corrosive gas heating. Fin spacing and size have been tested and selected to optimize performance. The sheath material of a finned tubular heater and its watt density are two critical factors that affect its durability.
