Knowing which band heater style best suits your application can minimize burnout and production downtime. There are 3 main types of band heaters: Mica, Mineral Insulated and Ceramic. So, what is the difference?
Mica heaters are economical and can be easily installed. Mica provides resistance to chemicals and water making them less subject to corrosion. They are best suited in applications where a lower operating temperature range is required (max. temp 900OF). Mica heaters are available in a wide range of sizes, up to a 44” ID and 15” width. The heaters are highly customizable and can accommodate a variety of construction and termination options.
Like the options that a Mica band provides but need a higher operating temperature? Try a Hi-Temperature (Hi-Density) Mica Band. This band offers the same custom benefits with a higher operating temperature range (max. temp 1200oF).
Mineral Insulated heaters offer higher performance capable of handling increased temperature (max. temp 1400oF) and watt density. Made with a compacted mineral that coats the band heater it provides good thermal conductivity and corrosion resistance. A bit more expensive than their Mica counterparts they can provide longer service life in applications with higher temperature requirements.
Ceramic segments used in these heaters make excellent insulators and provide long life and lower energy costs. They provide efficient heat transfer, however, because ceramic tends to hold onto the heat it makes it a bit more difficult to control the temperature. Ceramic bands are more expensive than other options but can make up for cost difference in heater efficiency and longer heater life (max. temp 1400oF).
Every application has its own unique requirements and challenges, heating processes should be evaluated for specific needs.
