Heat With Tubes: Tubular and Finned Tubular Type Heating Elements

In a previous TechTime article we discussed "Open Coil" heating elements along with their applications and advantages. This edition covers Tubular and Finned Tubular elements. Finned tubular elements have the same tubular coils but with fins wrapped around them.

Tubular and Finned Tubular types are the most dependable, versatile and rugged of any heating elements. They offer excellent heat dissipation, are less sensitive to humidity and dust and best suited for demanding environments. These heating coils offer an excellent advantage since the resistive element is not in direct contact with the air.

Tubular and Finned Tubular Type Heating Elements

Finned tubular elements are made of steel tubes with a diameter of 7/16" (11mm). The tubes come standard with steel fins to allow more efficient heat dissipation. Neptronic uses precision wound 80-20 nickel-chrome wire to deliver an even heat distribution to the element sheath. High purity, grade A magnesium oxide is used as the internal insulation to insure the best thermal transfer and insulation resistance. Electrical terminals (Stainless steel or Brass), mounting fittings and brackets, along with the wide array of bending options allow for easy integration into any heating system.

The tubes and fins can also be supplied in stainless steel for applications that require corrosion resistive elements.
