BAND HEATERS
Introduction | High Temp Mineral Insulated Band Heaters | Aluminum Shoe Band Heaters | Ceramic Band Heaters | Mica Band Heaters
CERAMIC INSULATED BAND HEATERS
Air Cooled Band Heaters
A perforated rather than insulated shroud with a cowl, plenum and blower is designed for use on plastic extension equipment where some processes generate excessive heat from pressure. Air Cooled Band Heaters When a predetermined temperature is exceeded, the blower will engage, cooling the process. Air Cooled Band Heaters

Ceramic heaters cam be manufactured in flat design for use as a strip heater, radiant heater or without shroud for use as a furnace element. 		Maintenance and Trouble Shooting for Prolonged Heater Life:
  1. Regulate Voltage. A 10% variation in voltage results in a 20% variation in power.
  2. The cylinder must be clean and smooth for efficient heat transfer.
  3. When attaching the lead wires to the terminals, excessive turning pressure can cause breakage of the terminal resistance wire.
  4. A ½" gap should be maintained at the opening when operating. Retightening is not normally required, however, if the operating temperature is changed, the flange bolt should be checked.
  5. Oil, plastic, dirt, etc., should not be allowed to accumulate on the heaters.
  6. Select a heater to match the diameter of the cylinder.
  7. Match the heaters as closely as possible to the actual load requirement.
