Features

Mica heating bands stand out for their ability to be designed and used in a wide variety of environments, making their use highly adaptable. These high-performance heating elements are specifically manufactured by Volton to meet the particular requirements of each project, thus providing uniform heat. Moreover, they can be custom-made to match all shapes and dimensions, allowing optimal adaptation to all types of environments.

Mica heating bands have been manufactured in our Montreal-North factory for over 50 years.

Technical Features

General Features:

  • 35W/po2 max.
  • Single-phase or three-phase
  • Dual voltage
  • Flexible band
  • Uniform heat (More heat at the ends of the band)
  • Integrated thermocouple
  • Maximum operating temperature 600°F
  • Made of either aluminized steel, ensuring better heat conduction, or stainless steel

Optional Features:

  • Special configurations available: Conical bands, partial bands, internal bands (terminals coming out on the inner face of the band), 2-section, 3-section, and more for large diameters, etc.
  • CSA & UL

Tips

Determine the inside diameter of your band heater as accurately as possible. A error of only 1/4" in the diameter measurement can make a difference of 3/4" on the circumference.

Tighten the screws of the Barrel-Nuts or Tabs, then tap gently with a soft mallet along the circumference to insure that the band heater is snug onto your cylinder. After a few minutes of heating re-tighten the heater.

Use several narrow width (1 ½" to 6") band heaters rather than one large one. A intensive study has shown that small narrow band heaters offer a more efficient rate of heat transfer and a longer lifespan.

To ensure that the internal electrical insulation of the band heater is not damaged, it is recommended to choose a two section (or two half-moon) heater if the cylinder on which it will be installed needs to be opened wide excessively (usually diameters over 10").

The cylinder on which the heater bands will be installed needs to have a smooth and clean surface. It is also important to avoid the accumulation of plastic residue or other contaminant on the cylinder.

Fixation

  Tabs/Flange
  Barrel nuts
  Quick latch & trunion

To quickly install and uninstall a band. When there is a lot of handling with the equipment.
  Wedges lock up

Exclusively for internal band heaters. The wedge lock-up makes it possible to maintain a constant tension between the external envelope of the heater and the surface to be heated.
