Non-standard position of cables or terminals: Cables or terminals can be attached along the belt heater wherever standard connections may not be accessible. Copper sheet with stainless steel hose: 3/8″ flexible hose welded to the angle is only available for configuration 415. When ordering, specify the orientation of the elbow to the heater. Holes or notches: Any appropriate size and position of holes or notches is available for custom heaters. Non-standard position of cables or terminals: Can be placed anywhere along the heater for applications where standard connections may not be accessible. Copper arch with stainless steel braid: available in some configurations.
Stainless steel housing: A stainless steel housing construction is available for food processing applications. There are different types of belt heaters for different solutions. These Mica Band Heater Manufacturer are the four types of belt heaters offered by Thermal Corporation. To avoid overheating, it is necessary to ensure uniform heat dissipation of the entire work surface of the heater.
Spring Clamps/Screws: Recommended for most large diameter applications, 10″ or larger to ensure proper fastening movement. By using ceramic fiber insulation between the ceramic and stainless steel enclosures, IHP reduces energy consumption by up to 30% compared to less advanced designs. Where ΔT is the temperature between the melt and the circulating liquid and the distance from the mold cooling channels, and A is the area through which heat is passed to the refrigerant.
Mica is used because it provides good thermal conductivity and dielectric resistance. The nickel-chromium resistance wire and mica sheets are surrounded by a corrosion-resistant outer steel cover. Ceramic belt heaters are made with a stainless steel cover that encloses the high-quality ceramic knuckles. Spiral high-temperature nickel-chromium element wire runs through these ceramic ankles. Depending on the application, extrusion heating belts have different diameters and widths.
Ceramic belt heaters are able to produce the highest temperatures, which are essential for the processing of today’s high-temperature resins. Electrical energy savings are achieved by using a 1/4″ thick ceramic fiber insulation ceiling, which reduces energy consumption by 25 to 30 percent. 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.
Copper sheet with stainless steel hose: 3/8″ flexible hose welded to the angle available in the 014 heating configuration. When ordering, specify the orientation of the elbow to the heater. Terminal Box – Available for configurations with postal terminals. 3-phase dual-voltage T-boxes: available in almost all configurations with pole terminals that lie side by side. Terminal Box – Available for all configurations with postal terminals.
Super Insulation Plus uses an additional 5/8 inch thermal insulation enclosed in a separate flexible stainless steel housing. Electric heaters work on the principle of resistive heating, in which an electric current flowing through a conductor generates heat. According to joule’s first law, the heat generated by an electric current is equal to the product of the conductor’s resistance, the square of the current, and the time in which it flows. Another simple driving tip is to use two wrenches to install the wiring at the rear ends of the belt. This practice can eliminate errors because the wrench in the lower nut of the rod acts as a relief from tensions.
