Heat Only

The channels in the specially designed extruded aluminum track have been precisely sized to accept a .315 diameter tubular heating element, and provide an excellent heat sink for rapid heat transfer and good temperature uniformity.

NOTE: See Additional Options for more Construction Options.

Cool Only

Stainless steel tubing for liquid cooling is placed in the specially designed extruded aluminum track.

NOTE: See Additional Options for more Construction Options.

Heat and Cool

The channels in the specially designed extruded aluminum track have been precisely sized to accept a .315 diameter tubular heating element and provide an excellent heat sink for rapid heat transfer and good temperature uniformity. Stainless steel tubing for liquid cooling is placed in the additional channels of the aluminum track next to the tubular heater. The overall low mass construction and high thermal conductivity of the aluminum provides extremely uniform surface temperatures and rapid cooling cycles.

NOTE: See Additional Options for more Construction Options.

Straps with Clamping Brackets

The clamping strap is made from a Low Thermal Expansion Alloy. It hinges at the terminal end to allow for easy installation. Specially designed mounting brackets with 1/4"-20 socket cap screws, located 180° from the terminal end, provide the clamping force required to tightly draw the heater assembly to the cylinder being heated.

NOTE: See Additional Options for Clamping Variations.

No Electrical Termination(s)

Electrical Terminations are not required in a Cool Only Maxiband.
If you want to add an Electrical Termination please change your Construction Style selection to Heat and Cool or Heat Only.

Type S: Terminal Lugs

Terminal Lugs with 10-32 binding head screws.

Type W3: Wire Braid Leads

Stainless Steel Wire Braid provides strength and protection to the lead wire’s insulation and offers sharp bending not possible with armor cable. The standard leads are 20" of wire braid over 24" of flexible leads.

Type R1: Armor Cable

Armor Cable provides excellent protection against abrasion and contaminants. The cable exits through an adapter that encapsulates both elements’ ends on each half. The adapter tube is tack welded to the heating element and the cable is crimped to the adapter for maximum security and seal protection. The standard leads are 20" of cable over 24" of flexible leads.

Type TS: Leads with Contamination Seal

Teflon® shrinkdown sleeving provides a good moisture and contamination seal. The sleeving is shrunk down on the element ends and is about 3-1/2" long. The maximum temperature allowed at the Teflon® seal sleeve is 500°F (260°C). The standard flexible leads are 24" in length.

Type EP: Explosion and Moisture Resistant Box

Maxiband heaters can be made with an explosion/moisture resistant box brazed on to the heater.

Type C3: General Purpose Terminal Box

Terminal Boxes provide a simple and economical way to eliminate all live exposed terminals and electrical wiring that can be a potential hazard. The boxes have a 1/2" trade size knockout (actual diameter 7/8") for standard connectors. The standard termination is Type S, Terminal Lugs. Heaters can be factory prewired with high temperature lead wire, armor cable or stainless steel wire braid.

Type P2: Quick Disconnect High Temperature Plug

Quick Disconnect Plug assemblies are highly recommended to provide the simplest and safest way to apply power to band heater installations.

Plug Electrical Ratings 2-Pole 3-Wire Grounding
Maximum Amps: 16
Maximum Volts: 250 VAC
Maximum Temperature: 572°F (300°C)

Type FF: Flared Seal Fittings

Brass flared seal fittings are well adapted for low to medium pressure and resistant to mechanical pullout. Available for 3/8" and 1/2" diameter tubing with SAE 45° flare.

Type HS: Hi-Seal Fittings

Hi-seal brass fittings are highly dependable under the most adverse conditions. For reliable and trouble-free service with ease of installation, we strongly recommend hi-seal fittings. Available for 3/8" and 1/2" diameter tubing. Male thread is 1/2" NPT for 1/2" tube and 3/8" tube.

Type RA: 90° Copper Elbow

90° copper elbow is brazed to the Cast-In Heater cooling tube extension with additional tube extension for connecting cooling lines with compression and/or flared fittings. Available for 3/8" and 1/2" diameter tubing.

Type RT: Cast Brass 90° Threaded Elbow

90° threaded elbow is brazed to the cooling tube extension, providing an easy and quick method for connecting cooling lines. Recommended to be factory installed to assure good braze seals. Available for 3/8" and 1/2" NPT internal threads.

Type R3: Straight Threaded Copper Fitting

Straight threaded fitting is brazed to the cooling tube extensions, providing an easy and quick method for connecting cooling lines. Recommended to be factory installed to assure good braze seals. Available for 3/8" and 1/2" diameter tubing with internal threads. /

No Cooling Tube Fittings

Cooling Tube Fittings are not required.
If you want to add an Electrical Termination please change your selections above.

Type EC: Insulated Shroud

Insulated Shroud provides energy savings.

Available on all Maxiband widths except 3/4".

The shrouds are a separate component part and fit over the Maxiband heater.
Insulated shrouds to cover entire heat zones are available and are made to customer specifications.

Type SL: Spring-Loaded Clamping

On Maxiband heaters over 12" in diameter, the aluminum tracks are in segments for better configuration, and the straps are equipped with two or more Spring-Loaded Clamping Brackets.

For excessively large diameters, four tubular heaters will be used, each heating a 90° section of the total diameter. When terminal boxes are required, two boxes will be used.

Type RC: Reverse Construction

Reverse Maxibands lend themselves to heating cylindrical surfaces from the inside out.

The specially designed internal brackets exert pressure to both heater halves to assure good contact against the inside diameter of the part being heated.

Reverse HLC Maxiband minimum OD is 5-1/2".

Made strictly to customer specifications.

Due to size/construction restrictions, some termination styles are not possible.

Partial Coverage

Partial coverage band heaters are normally required when holes and cutouts will not allow the heater to sufficiently clear the machine obstructions. The preferred method of construction is the 2-Piece Maxiband Heater with Built-In Brackets. The heater is screwed down to the cylinder at the ends and the Built-In Brackets pull the heater tightly against the cylinder being heated. It is available with all types of construction and termination variations. When ordering provide the angle of coverage from center to center of the mounting screw holes as shown.

Dual Voltage

Ground Terminal or Lead

Electrical Plugs

Terminal Lugs

Extra Cooling Tube Length

Square or Rectangular

Square or Rectangular heaters, normally used for heating dies on plastic extruders, are made in a two-piece construction for better clamping and to provide good surface contact. Made strictly to customer specifications. When ordering or for quotation purposes, supply a detailed drawing or sample part.
