Watt Density

Formulas

Watt Density Formula for Band Heaters with Posts = Wattage / (Heater I.D. x 3.14) - 1.75 x Width
Watt Density Formula for Band Heaters with Leads = Wattage / (Heater I.D. x 3.14) - .75 x Width

Clamping Options

There are various options for mounting and clamping your band heater.

	Full-Length Band Clamp Low thermal expansion alloy strap to tighten around whole circumference of heater, allowing maximum contact between heater and working surface. 5/8" strap on heaters greater than 1.50" wide. 1/2" strap on heaters less than 1.50" wide. Standard gap .300" Standard for 1pc heaters
	Welded-On Clamp Welded on barrel Nuts are optional on any screw or lead termination. Excellent clamping option for heaters with holes or cutouts. No strap to loosen or adjust. Standard Barrel nuts are 3/8” diameter and use a #10-24 socket head cap screw. 5/8” clearance required. Standard for 2pc heaters
	Wedge Wedge mount is ideal for low profile clearance and when access is limited. 1/8” clearance required. Min I.D. 1” Min width 1” Standard wedge exit is out each side of gap.
	Flange Flange lock up is best for heaters with multiple holes or cut outs. 1/2” clearance required Min. I.D. 1” Min. width 1”
	Spring Loaded Clamping Tig welded barrel nuts. Spring loaded clamping. Retains tight heater fit during start-up. 4" long bolt (#10-24 thread) with 2.25" long spring.

Custom options available from BriskHeat

Three Phase	Three phase construction for high wattage heaters.
Dual Voltage	Dual voltage wiring allowing the heater to run on either voltage at the same wattage is available on any clamping or termination design.
Ground Lead	Ground lead or terminal is available on any design.

Launch Book

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.

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.
