Do's and Don’ts
  • Please take care while fixing heaters and selecting watts check Volts rating of heaters before connection. Heater rated for particular volts should never be connected to higher volts rating.
  • These heaters are flexible and heat transfer is by conduction from inside surface so perfect matching of dia is important.
  • No foreign materials such as polymer, oil, water etc, should fall over the heaters. They should be well covered.
  • Choose appropriate watts as per calculation. Under rated watts will result in heater failure.
  • Temperature control should be taken care. For higher temperature application do inform us while ordering.
  • All heaters come with internal ceramic fiber insulation for energy saving. Additional cover can be provided upon request at additional cost. Do infor at enquiry stage. Good only for sizes bigger than 100mm dia.

Frequently Asked Questions

Ceramic Band Heaters are highly efficient industrial heating elements designed to provide uniform and consistent heat to cylindrical surfaces. They utilize high-grade ceramic insulation to allow for higher operating temperatures and excellent thermal transfer, making them ideal for a wide range of industrial applications.

Key advantages include superior energy efficiency due to ceramic insulation, excellent heat transfer and uniformity, robust construction for extended operational life, and the ability to achieve higher operating temperatures compared to other band heater types. Their design minimizes heat loss, contributing to lower energy consumption.

Ceramic Band Heaters are widely utilized in industries requiring precise and efficient heating of cylindrical parts. Common applications include plastic processing machinery (e.g., injection molding, extrusion barrels), pipe heating, tanks, drums, and other cylindrical process equipment in various manufacturing sectors.

Their energy efficiency stems from the use of ceramic insulation and an internal ceramic fiber mat. This design significantly reduces heat loss to the ambient environment, directing more heat towards the heated surface. This allows for lower sheath temperatures and more effective heat transfer, resulting in reduced power consumption.

Uniform heat distribution is achieved through the precise winding of the resistance wire within the ceramic segments, which are designed to provide consistent spacing and contact with the heated surface. The ceramic insulation and internal fiber mat also contribute to directing heat efficiently and evenly across the band.
