Type P - Bolt Clamp

Features standard 1" high fins and 1" thick body, utilizing bolts and nuts for clamping. Fins cover approximately 100% of heater width. Supplied with Type "S" Termination if not otherwise specified.

Type FF - For Forced Air Shrouded Systems

Features standard 1" high fins and 1" thick body, utilizing 3/4" to 1" wide clamp straps. A 1" high by 1/4" thick shoulder at each end of the casting mates to the I.D. of the Cast Aluminum Shroud. This unit is normally supplied with Type "E" terminals. Specifically designed for use with forced air shrouded systems and can be used for other air cooled applications.

Type F - Strap Clamp

Features standard 1" high fins and 1" thick body, utilizing 1" wide strap clamping at either end of the heater. Fins cover approximately 80% of the heater width. Supplied with Type "S" Termination if not otherwise specified.

Type LP Low Profile for 1" to 1-1/2" Extruders

The Type LP design is intended to be used on smaller tabletop extruders--1" to 1.5" screw sizes. This unique design features 1" high fins, which have smaller radii at the fin's crest and root. This results in:

• Less heater mass to heat up and cool.
• More cooling fins, yielding greater than normal surface area to dissipate BTU's.

Clamping is achieved by a unique, low profile bolting method that allows the maximum use of surface area for fins, not clamping mechanisms. If not otherwise specified, supplied with Type "S" screw terminals.

Type AW--Dual-Cooling Functions

This design allows the user to maximize cooling capabilities as cast fins and cooling tubes are both incorporated into the heater. Blowers and liquid flow can operate simultaneously for maximum cooling capacity.  Available with straps or bolt and nut clamping in finned design styles P and F. If not otherwise specified, supplied with Type "S" screw terminals and 3" long cooling tube extensions. This type of Cast-In Heater is manufactured on a per order basis.

In order to assist you in selecting the exact heater replacement for your machine, have the following information ready:

• Measure the O.D. of your barrel, which in turn will be the I.D. of the heater.
• Measure the width of your heater.
• Check the wattage and voltage rating per half or per segment. This information is normally stamped on the heater.
• Establish heater cooling function, if any. If water cooled, measure length and diameter of cooling tube extensions. Cooling tube extensions are 3" long, and 1/2" * .049 O.D. wall thickness unless otherwise specified. If air cooled, Cast-In Band will have cast fins.
• Check for special features such as: thermocouple clearance holes, drill and tapped holes, vent cutouts and terminal boxes.
• There are two methods for securing a Cast-In Band Heater to a barrel; separate clamping straps or nut and bolt clamping.
