Smaller Diameters (up to 3½")

Our stock band heaters with diameters up to 3½ inches are built with one-piece (slide-on) construction.

If none of these band heaters is right for your application, you can configure your own band heater in any size and configuration, get an instant quote, and order online. If you have any questions about stock or built-to-order band heaters, please send us an e-mail, fill out one of our contact forms, or give us a call at (866) 685-4443.

Stock band heaters usually ship within 3-4 business days after an order is placed.

SF3B: Simple post terminals.
SF16B terminals
SF16B: Leads exit on either side of gap. Stock leads are 18 inches long, with first 12 inches enclosed in stainless steel braiding.

Wattage

The maximum watt density (W/in²) that should be used is determined by the maximum temperature to be attained. Processes that involve a higher temperature call for a heater with lower watt density, so as to maintain longer product life. Excessive watt density stresses heaters and causes them to burn out. Follow the guidelines below for the longest service life from a band heater:
Operating temperature Max. watt density
300°F 40 W/in²
400°F 30 W/in²
500°F 21 W/in²
600°F 12 W/in²
700 to 900°F 10 W/in²
