Regular opening and 45 W / m2. Features include built-in fiber jackets, pool clips, terminal boxes, stainless steel braided cables, armored cables, and European connectors. Applications include spray and blow molds, plastic extrusions and containers, and heating of pipes and tanks. WATTCO heating elements are the ideal solution for high water densities and applications with high operating temperatures, especially for the plastics industry. The different types of belt warmers available at WATTCO include mica-insulated belt warmers and ceramic belt warmers.
In addition, knuckle heaters offer double heat transfer, so an almost perfect fit is not necessary as with other heaters, such as mica stoves. Because most of the heat goes directly to the process, the ceramic belt heater emits significantly less heat to the ambient air than a mica tire heater. Ceramic knuckle belt warmers during the day. Characteristic of stainless steel cover with ceramic knuckles and nickel-chrome element wire for high temperatures.
With a nominal temperature of 600oF and a water density of 35 to 40 W / in2, these heaters are durable and resistant to contamination of plastic, oil, and other materials. In this article, we guide you through the differences between mica belt warmers and ceramic belt warmers to help you decide which one to use for your heating application. Because mica belts are conductive heaters, intimate contact with the surface to be heated is important to ensure long service life.
All this insulation produces a more efficient ceramic belt heater compared to a mica belt heater. Ceramic belt warmers also offer a “ventilated outdoor pod” option. Release heat from the process, if necessary, for application. The extruded aluminum belts are designed with tubular heating elements that operate on an accurate forest in an extruded aluminum segment.
Not understanding the internal design of a heater often leads to heating losses. Some manufacturers offer belt warmers similar to mica tires that can be stretched for installation, but using inappropriate installation techniques for a specific type of heating will cause problems. A two-piece design is also a good option when a large diameter tire is required: the two-part design minimizes the possibility of airspace developing. Two-piece ceramic belts can also be used in large diameter drums. When it comes to watt density, mica belt warmers have a higher density than ceramic belt warmers.
Pipe heating, drum heating, and barrel heating are normally used for oils, lubricants or other round applications. Tire heaters use electric heating elements to heat the outer surface of vessels or pipes for gradual heat transfer. Tire heating is an indirect form of industrial heating and provides safety by heating volatile and explosive substances, as well as pipes or containers that otherwise cannot be heated using direct heating methods.
The round micafole is contained in a stainless steel or aluminum jacket together with the encapsulated resistance cable. Mica belt heaters are used to heat the contents of cylinders, nozzles, and pipes. They can also supply heat in injection molding, blowing casting, and extrusion machines. Adapted manufacturer of belt heaters for the chemical, fuel cell, heat treatment, packaging, pharmaceutical, plastic, semiconductor, wire, cable, oil, and gas industries. Available in different tube sizes and configurations. Insulated ceramic and mica heaters are offered.
Standard ceramic belt warmers have a 3/8 ″ thick ceramic insulation layer on the knuckles and then a stainless steel outer hood that brings back heat in the process. The ceramic band insulation option “Heat Saver” has a 1/8 ″ thick ceramic paper layer with a reflective stainless steel cover
on it and then another 3/8 ″ thick paper layer, with an extra pod on it. All this insulation produces a heater with greater efficiency vs. a mica band heater. Ceramic belt warmers also offer a “Fired Outer Layer” option, shown in the image below. This allows heat to escape the process, if necessary for its application.
Ceramic knuckle belt warmers offer lower operating costs: superior insulation means less heat flow leaks into the air and less power is required to maintain the fat temperature. Ceramic fiber insulation reduces energy consumption by 20% to 30%. Ceramic heating belts offer higher operating temperatures and a longer heating life because all materials used are classified to operate at very high temperatures.
Some heaters are energy-efficient, polluting, and have rust-resistant covers. Suitable for drums of plastic injection molding machines, plastic extruders, reciprocals, chemical processing, cylindrical pipes, molds, and molds.
