Selection Of A Belt Heater To Avoid Power And Loss

The wires are joined before the final outer sleeves are connected to complete the heating. Our Mica Band heaters can be installed directly on drum heaters without the need for initial heating fuel extraction. Push the heater through the low thermal expansion outer shell until the jagged edges are firmly secured with the cylinder. Do not squeeze too tightly to prevent the jagged edges from collapsing and protruding outwards.

Instead, it is often environmental factors that cause a short circuit, create hot spots, or simply push the heater beyond its normal operating temperature. All these factors cause a heater to fail prematurely and need to be replaced. Of course, minimizing these environmental factors can reduce the frequency of replacing belt heaters in your operation. These heaters are used for plastic molds, extrusion Industrial Band Heater Manufacturer and molding presses, pipe heating, heat treatment and autoclaves, food industry and much more. Our warranty for custom-made heating tapes extends over a period of 12 months from the date of purchase and covers failures due to defects in materials or workmanship. Ceramic elements are thicker in construction, but offer a wattage of 5.5 W/cm² and an operating temperature of up to 600°C.

To maximize surface contact, our belt heaters are carefully rounded and shaped to optimize your grip. The outer metal protective jacket of our belt heaters is made of a special alloy that expands less when heated than the barrel. This difference in thermal expansion causes the heater to grip firmly as soon as it is energized. This improves heat transfer, which extends the life of the heater. The construction of a standard mica band heater consists of resistance wire that is wound at an even distance over a flexible mica insulator to form the inside of the element. This is covered on each side with additional mica insulation and installed in an outer metal housing before the assembly forms to the desired diameter.

If a tape cannot be installed above the barrel end of a machine without stretching the heater, use a heater that is more suitable for the application, e.B. A two-piece design is also a good choice when a large-diameter tape is required: the two-piece design minimizes the possibility of developing airspace. Two-piece ceramic tapes can also be used on large diameter barrels. A mineral-insulated tape provides the highest temperature capabilities.

Open coil heaters can be used as cartridge heaters in irregularly sized holes. Backer Marathon belt heaters are designed and manufactured by the computer to your specifications.
