Band, Plate & Strip Heating

Band Heating, Plate Heating & Strip Heating Elements

This group of heating elements create even and fast heat along with good temperature control, making them perfect for a wide range of applications. Whether using mica strip or ceramic bracelet insulation these heaters are versatile and economical. They provide excellent thermal conduction which offers precise process heating.

Band heating, plate heating and strip heating elements temperature capabilities are up to 850 degrees celcius which allows both for fast cycle times and the most advanced engineering resins to be moulded.

Band, Plate and Strip Heating Applications

There are a variety of applications for these type of heating elements, some of which include:

  • Plastic Extrusion & Injection Moulding
  • Blown Film Extrusion
  • Pipe Heating
  • Heat Treating
  • Hot Plates & Sealing Equipment

Band Heating Elements

Band heaters provide heating solutions for cylindrical applications. Applied to the outside of a cylindrical container, band heaters produce safe, even heating. Specifically designed to apply heat via conduction to cylindrical surfaces band heaters are commonly used for heating large diameter pipe sections or heating barrels.

They are especially significant for reducing the viscosity of barrelled liquids like oil, tar and grease and preventing them from freezing inside containers. We have provided more detailed information on this particular application under drum heaters for your convenience.

Coming in many sizes and deviations, band heaters can accommodate for use in a large number of situations. They provide a great source of indirect heating, which is applied directly to external circular surfaces for gradual heat transfer. This application is perfect for when safety is paramount in heating violate explosive substances or where direct heating solutions cannot be applied.

Cynebar provides high quality, band heating elements in a range of dimensions to fit any task. Selecting the right band dimension and size are important in ensuring it works best for your application.

Consider the inside diameter, width and thickness of a heating band when making a choice. Keep in mind that the inside diameter of the band heater should be identical to the size of the outside diameter of the cylinder requiring heating.


Band Heating Insulation Options

Insulation options are another factor when purchasing a new band heater, as they focus heat directly to your application and minimise heat-loss:

  • Uninsulated

    Band heaters that are useful in tight spaces due to their lower profiles. They do lack the energy efficiency of insulated bands so are used only in specific circumstances.

  • Ceramic insulation

    Made from non-metallic minerals such as clay that is hardened by high-temperature firing, this insulation provides resistance not only for heat but chemicals. They also provide outstanding energy conservation.

  • Mica insulation

    A natural mineral, Mica is used in a wide array of applications due to its excellent electrical insulating properties. With a high resistance to heat, good high-watt density capabilities and cost effectiveness they are used in conjunction with many band heating variations.


Band Heating Configurations

Band heaters have different strap, welding and mounting configurations to attach onto the surface of what they are heating. We have different band heating and clamp ranges to fit best the current application. Here are just a few setups we can assist with:

  • Standard independent straps

    They go on around the cylinder's surface and are clamped tightly to ensure maximum surface contact. With draw force equally spread around the band heater, heat transferring is improved.

  • Welded

    Barrel nuts are welded over the screw of lead termination in lieu of strap configurations, so there is no need for constant adjustments.

  • Wedge lock

    When there is limited space above the heater, a wedge lock construction can be the ideal solution, especially if access is limited.

  • Flange lock

    Used in narrowing heating applications with holes and cutouts, while not always providing the best contact with the surface, they can be economical and easy to install.

  • Spring loaded

    Independent straps utilising welded barrel nuts and spring loaded clamping. Retains a tighter fit during heater start-up before allowing for thermal expansion.

Most band heaters have multiple options when selecting a termination type. This refers to the way an electronic connection attaches to the heater. From insulated leads to terminal boxes we will make sure your band heater fits your current electrical setup.

Plate Heating Elements

As simple as it sounds - Plate Heating uses a metal plate to heat objects, liquids and gases. The simplest example of a plate heater is a kitchen hot plate, where the heating occurs to bring the temperature up to a fixed level, and maintains an even heat across the plate.

Although in industrial applications sizes and uses can vary largely from this, they use tubular heating elements involving resistance wire technology. These tube-shaped wires are accurately set into position providing an equal coverage of consistent heat distribution along the surface of the plate.

Whatever the load, big or small, when you need heating under an object at controlled, uniform temperatures, Cynebar has plate heating elements and designs for all industrial conditions.

With a wide range of shapes and sizes to fit any spacing requirements, and a focus on high-quality, longevity, good insulation and consistent temperatures, there are several variants of plate heating elements we can employ.

Strip Heating Elements

Strip heaters are a heating solution used most commonly in air heating configurations or for folding and shaping plastics. Their construction - depending on their intended application - can vary greatly, but they work under the general principle of using surface area to effectively transfer heat. They are comprised of a flat metal component cut to a specific size for its task and a sheath made of insulated metal that separates the heating core.

Strip heater temperatures can vary greatly depending on wattage, intended use and sheathing design. Due to their broad temperature capabilities and affordability, strip heaters are uniquely useful in many situations. They are frequently used in the process of heating air in cabinets or baking ovens and for moisture protection for sensitive electrical components.

Strip heaters offer greater flexibility when heating small areas. Their size and ability to be mounted securely on many surfaces using clamps or bolts makes them the perfect heating element asset in many situations. Their terminal can extend from the sheath for easy electrical connections, and there are various termination configurations and options available.
