  • Our Thinband heater is the redesign of the mica band heater. Thinbands offer significant flexibility because they can be opened to the full length of the band (also called a barrel) without causing damage to the internal design of the band heater. Thinband DiagramedThinbands can be installed directly onto barrel heaters – without needing to remove the initially installed heater. Thinbands have a more precise one-piece design with narrow fold-over inner edges. Thinbands only require one set of leads or terminals which are applied at the end of the construction process. At Heat and Sensor Technology, it is our standard practice – to assemble each Thinband we manufacture with a polished and pristine finish. For the fastest installation… Consider requesting the Quick Clamp latch variationThinband Quickclamp Heater (this styling’s available only on stock Thinband barrels). To see our full line of Thinband Heaters, and our GLOSSARY more of our “in-house” definitions, see all our Thinband Products: Thinband Options, Thinband Stock List, Thinband Barrel, Thinband Nozzle from our website: wwwheatandsensortech.com. Thinband Configurators: Our Thinband Stock Configurator and our Thinband Custom Configurator, allow you to select Thinband components – with ease and convenience direct from our website home page: www.heatandsensortech.com.

    Thinband Benefits: Thinband Heater Side View

    • 50,000 variations can be created for Thinbands lead attachments with our exclusive Lead Adapter — or LA — manufacturing method, that significantly reduces costly downtime.
    • Flexible one-piece design equals faster installation on plastic processing equipment.
    • All Thinband heaters can be installed on a barrel without removing pre-existing heaters.
    • The terminals have a more finished and polished appearance.
    • They are built with a thinner core and smaller fold-over.
    • They operate at temperature up to 1400°F
    • They have higher watt densities than other bands
    • They have high thermal conductivity of MI (mineral insulation)
    • They have a stainless steel cover
    • They are contamination resistant, and they have no folds on the outside.
    • The clamp variations have permanent attachment
    • They need just one set of leads or terminals

    Performance Capabilities: • Sheath temperatures to 480°C (900°F) • Watt densities to 8.5 W/cm2 (55 W/in2)

  • Thinband Physical Limitations of Lead Variations

    Special Considerations:
    Review our table below – to be certain the variations and lead arrangements you need are available in the band heater size you require. Note some combinations of maximums and minimums cannot occur on the same heater. Standard gap is 9.53 mm (0.375 in.) between clamp bars.

    If you need to exceed listed limitations, please contact our Quote Specialist at: 513-228-0481 Ext. 203, or Email us: info@heatandsensortech.com to discus a customized order.

    Thinband Maximum allowable Watt Density Graph

    Use as low a watt density rating – as your application will permit. A close match of the heat supplied (to the actual requirements) will reduce temperature overshoot and cycling, and will increase the life of your band heater.

    Calculate Safe Maximum Wattage for Your Heater…

    Heated Area x Maximum Watt Density:

    Determine the maximum watt density of your heater from graph on this page. (Note: The curves are based on narrow heaters mounted on a smooth, steel cylinder.)

    Calculate the heated area of your barrel heater: Subtract the no-heat area from the total area in contact with the cylinder (3.14 x I.D. x width). Subtract the no-heat area at the terminals and any additional no-heat areas caused by holes, slots and over-sized gaps.

    Apply the necessary correction factors:

    • For heaters 57 mm (2.25 in.) to 127 mm (5 in.) wide, multiply watt density by 0.8.

    • For high expansion cylinders (aluminum or brass), reduce the watt density by 0.46 W/cm2 (3 W/in2).

    • For heaters 57 mm to 127 mm wide (2.25 in. to 5 in.) installed on a high expansion cylinder, reduce watt density by a total of 0.46 W/cm2 (3 W/in2) only.

    • For regular cylinder surfaces other than smooth, machined finish, reduce watt density by 0.46 W/cm2 (3 W/in2).

    • For heaters that will be insulated or enclosed, contact Heat and Sensor Technology for specific watt densities.

    • For units greater than 355 mm (14 in.) diameter, consult recommended clamping graph.

    Thinband Installation Proceedures:
    thinband-installed

    Featured: Quick Clamp Heater

     

    1. Install heaters over a clean surface.

    2.
    After installing the band heater unit, begin to tighten the clamp screw. The clamping screw is a 5 mm x 1.25 inch, allen head cap screw. Begin tightening the clamp bars. If the clamp bars appear not to have seated, tap the clamp bars with a small hammer to insure the bars are well seated in the angle formed by the 60 degree bent tab and the heater.

    3.
    If the bar has multiple screws, alternately tighten the screws to insure even loading – as you should tighten lug nuts in a star shaped pattern to secure a wheel on a car.

    4. Torque all screws to approximately (9 N-M) 8 Ib-in.

    5. Take a soft rubber mallet and tap gently around the circumference of the heater while tightening the screws. This will ensure the heater’s fit to the barrel is maximized without any air gaps.

    6. When installing terminal lugs, torque the top nuts to 30 in-lbs. The bottom nut should not be touched as it is factory torqued to 45 in-lbs. at assembly.

    7. Re-tighten the heater after the heater has operated for a short time. Always make adjustments when the heater and cylinder are cold. Heat and Sensor Technology
