Finned
Tubular Heater Application Basics
The Finned Tubular Heaters are manufactured with the same
construction as the Tubular Heaters without fins. These units
incorporate a continuous edge wound fin on the heater tube in
order to efficiently dissipate heat from the heater. These
heaters are designed for gas and air heating applications with
the ability to provide a high concentration of heat. The
internal compacted MgO insulation construction provides
excellent heater durability and design versatility. A major
advantage of Finned Tubular Heaters is the ability to form into
custom shapes.
This heater construction is used on all Vulcan Finned Duct
Heater assemblies. Steel sheath and brazed fin with a high
temperature corrosion resistant finish is the standard
construction. Stainless or Nickel alloy sheath with a stainless
steel fin is also available for high temperature and more
corrosive environments.
Higher wattages over a smaller heater surface area can be
achieved with increasing air flow over the heater. Attention
must be given to the free movement of air around the heater,
particularly if several heating elements are combined in one
system. Applications incorporating several rows of elements
should be tested to ensure elements downstream of airflow do not
exceed recommended sheath or application temperatures and that
hot spots do not occur.
Units requiring fan or blower operation, should be wire in
such a way that a failure in the fan motor or stoppage of air
will automatically shut off the heater.
Do not use standard construction heaters in a hazardous or
explosive environment. Armorwall heaters manufactured with heavy
wall tubing are designed for this application purpose. Please
contact Vulcan Electric for details.
As with any electrically heated product, the proper
application of Vulcan Heaters and the temperature control is the
most important factor in optimum performance, efficiency, and
longevity. No two systems are alike. It is extremely important
that attention has been given to the total product or system
design as well as operating environment.
Please refer to general application guidelines,
recommended watt densities, sheath temperature limitations,
corrosion guide, and other engineering data to assist you with
product selection.
