What is the difference between a Band Heater and a Nozzle Heater?
A nozzle heater is a smaller version of a band heater. Typically, a heater with a diameter of 3 in (76 mm) or less is considered a nozzle heater.

What is Mica and why is it important?
Mica is an electric insulation that surrounds the heating elements in band and nozzle heaters. It provides the dialectric strength needed for demanding applications.

What is the maximum watt density and operating temperature of a BriskHeat band or nozzle heater?
Maximum watt density is 40 W/in² (6 W/cm2) and maximum operating temperature is 850°F (454°C).

What 3rd-party approvals do BriskHeat band and nozzle heaters have?
By request, BriskHeat band and nozzle heaters can be manufactured to UL Standard UL499 and CE compliance.

Can these heaters be used in washdown areas or outdoors?
Yes, but certain options are better than others. Consult BriskHeat for assistance.

What if the cylinder I need to heat has obstructions?
BriskHeat band and nozzle heaters can be made with cut-outs, holes, and slots.

Are all band and nozzle heaters cylindrical-shaped?
No. BriskHeat can also supply these heaters in “box” or rectangular shapes.

Are BriskHeat band and nozzle heaters approved for hazardous locations?
No.
