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.
Additional Options
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
Maxiband heaters can be designed using series/parallel circuits for dual voltage applications. Whether the heater is run on a higher or lower voltage, the wattage will be the same. Dual Voltage is available on all Maxiband heater widths except 3/4″.
Ground Terminal or Lead
For those applications requiring a separate ground terminal or lead attached to the heater. A Ground Terminal or Lead is available on any construction or termination variation.
Electrical Plugs
Industry-standard NEMA twist lock electrical connectors are available. The plugs can be attached to fiberglass leads, armor cable, or wire braid. Electrical Plugs can be added to any clamping, construction, or termination variation.
Terminal Lugs
Various types of crimp terminals can be attached to the heater leads to make wiring into applications quick and easy. High-temperature 1200°F (649°C) ring terminals and nylon or PVC insulated terminals are available. Spade, ring, and right-angle or straight quick disconnect type terminals can be attached to the leads.
Extra Cooling Tube Length
The standard cooling tube length is 4″. Longer lengths can be provided; please specify when ordering.
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.
