Built in insulation minimizes unwanted change in temperature along the barrel.
Efficient heat transfer: Heat transfers through radiation, conduction, and convection, so a perfect fit is not required compared to other band heaters.
Heat transfers are not affected by irregular surfaces or a loose fit.
Because they operate at higher watt densities, they can be used in wider increments.
The number of bands used can be reduced with simplified wiring.
The heater is safer with the cooler external surface – over other band heaters.
The flexible design allows easy install and removal.
