  The flat shape of the Bar provides greater surface area
   inch for inch of length than round elements.
   With the Bar heater, equipment can he designed with
   more wattage in less linear space than with conventional
   elements.
   Or, by replacing an existing tubular heater with a Bar
   heater of the same length, the watt density is significantly
   reduced.


  In immersion applications the narrow profile increases natural convective flow of materials
  being processed, esulting in lower sheath temperatures and improved heat transfer to the
  process.
 
  Materials being processed are less susceptible to degradation.
  In processes where these considerations are not as critical, watt densities can be
  reasonably increased.

  The .275" x 1" dimension creates anti-corrosion,self-cleaning effects that significantly
  extend the Bar useful life by not allowing the  collection of foreign materials on the sheath.

  The multiple coil design permits an individual element the flexibility to be wired at the
  installation in single phase, three phase, three heat or dual voltage.

  The Bar heater can be used in virtually any immersion, clamp-on, forced air or radiant
  heating application.

  A bar heater has over 50% more surface area per inch of length than a diameter 12mm.
  tubular element.
  2.55 square inches per linear inch on the Bar heater versus 1.49 square inches per linear
  length on the tubular allows more wattage or lower watt   densities.

  The narrow width and greater surface area of the Bar heater increases the velocity of many
  materials as they flow past the sheath.
  Heat transfer is improved and the Bar heater operating sheath temperature is lower than a
  tubular element.

3. TYPE OF HEATER

    The unheated area from the termination end to the initial end along with minimum
   dimensional requirements are primary considerations when forming a Bar heater element.

   Parameters of the five possible types of bends are shown for use when designing a Bar
   heater.
