The ceramic stones and components in them are located in the inner circumference of the round metal jacket. The metal cladding is typically made of stainless steel and aluminum; It can be coated with a suitable finishing material for better corrosion resistance and durability. The metal cover offers mechanical stability, resistance and flexibility to the composite heating element. The insulating blanket prevents heat loss from the resistance cable by 25-30%.
The temperature of the operating slide must not exceed 850oF . Mica belt warmers consist of a resistance tape around the mica insulation. The mica insulation is folded over a mold to form a circular band.
Ceramic belt heaters are high temperature heating elements that are durable and now available with 1/4 “or 1/2” insulation. Radically different in mica band design, ceramic insulated belt warmers have a nickel chrome-resistant cable that is wrapped helically through small ceramic blocks. The series of ceramic blocks is placed in a stainless steel outer shell covered with ceramic fiber insulation. The housing has serrated edges so that the belt can expand completely during installation. Ceramic belt warmers consist of a set of wound resistance cables embedded in ceramic fiber insulation, which are located in ceramic bricks.
Because the resistance tape in a mica belt heater is well between mica pieces, there is better heat transfer from the tape to the outside surfaces of the heater. Mica belt warmers will also generally have less heated surface than a ceramic belt heater, especially in smaller belt heaters. Mica belt heaters may have a higher watt density than ceramic belt heaters. In general, mica band heaters will also be less unheated than a ceramic belt heater, especially in smaller belt heaters. Ceramic belt warmers ensure a long service life and consume less power in plastic extrusion and injection molding applications.
Configuration options include one or two-piece heaters, type of closure and type of cable / pool terminals. WATTCO belt heaters can be found in different types of dimensions, strength, stresses and material. Mica belt heaters are a cheap industrial heating solution that surrounds pipes and tubes that require indirect external heating.
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.
Industrial belt heaters can be made with NEMA 1 terminal boxes or NEMA 4 moisture-resistant terminal boxes that protect the finishes and have the option of a digital temperature controller or thermostat to help control and control the applied heat. Insulation is also required to direct heat to your application rather than experience heat loss and a slow warm-up time. Manufacturer of standard and custom advanced ceramic belt warmers. Specifications include 350 degrees F to 450 degrees F of outdoor temperature housing, 2 inches.
The heat produced by the resistance cable is transferred by conduction or radiation. And a ceramic belt heater is that mica tires are cheaper, can have a higher density of watts and are easier to adjust, while ceramic belts are more efficient, can withstand higher temperatures and generally last longer. By choosing between a mica belt heater or a ceramic belt heater, you finally arrive to investigate your heating process and your specific belt heating needs.
