Finned Tubular Heaters, Finned Tubular Elements

Finned Tubular Heaters-With and Without Fittings
 

PRODUCT DESCRIPTION GUIDE:

Finned Tubular Heaters are normally used in forced circulation heating of low temperature air, other atmospheres and gases. Suitable for use in a wide variety of forced air heating applications, industrial ovens and food service applications. Steel finned heaters are standard with surface temperatures limited to about 425C (797F) compared to 815C (1500F) for an alloy sheathed non-finned heater.

Some applications require stainless steel materials for corrosion resistance. The most efficient finned heaters are made with steel sheath and steel fins. Steel is normally used for air heating, stainless steel for atmospheres which are humid or corrosive and monel for salt-laden humid atmospheres. Keep in mind that stainless heaters with stainless fins are very inefficient since the heat transfer rate of stainless is less than one quarter that for steel.

Finned Tubular Heaters offer distinct advantages over open coil heaters: (a) they are safer to operate in that the risk of fire or electrical shock are minimized; (b) they have a much longer service life; and (c) they are more rugged requiring less maintenance than open coil heaters.

We offer a standard carbon steel construction and a high temperature/ corrosion resistant stainless steel construction. As with regular tubular elements, they can be bent to a number of shapes and are available with fittings and mounting brackets as required.
