Cast Band

The cast heater is the toughest band available; it can withstand most rough handling, shock and vibration.

The heating element is completely isolated from the outside of the band, so it can withstand almost any type of contamination.

Cast heaters are constructed of Aluminum, Brass or Bronze and can be produced with or with out cooling tubes and an endless variety of shapes and sizes.

Features & Benefits

  • Toughest band available
  • Can withstand almost any type of abuse without failure
  • Can withstand almost any type of contamination
  • Constructed of Aluminum, Brass or Bronze
  • Can be produced in an almost endless variety of shapes and sizes
  • Air Cooled Finned
  • Liquid Cooling

Castings can be used to heat dies, extruders, chemical valves & pipelines, and also to heat & cool oil. These bands will take almost any type of abuse without failure.

  • Plastics - Best choice for processing engineering grade resins
  • Heating Pipes
  • Chemical Processing
  • Drum Heating
  • Semi Conductor
  • Food Process
  • Packaging

If you have a special application, Cast Bands can also be modified to meet these demands. Our engineers can utilize a variety of alternative features and options to customize the heater to your specific needs.

Plain Leads

High temperature mica tape lead wire is suitable up to 842° F (450° C) max. with nickel stranded conductors. Outer jacket is glass Teflon® finish. The use of Monel® lugs is recommended. Better Band comes standard with mica tape lead wire.

Sleeving

Fiberglass silicone rubber coated sleeving class c -1, 392° F (200° C ) service. Provides extra insulation where wire is exposed to heat, molten plastics or abrasion. Rated 1500 volts at 428° F (220° C), except 5/16" (7.9 mm) size which has no voltage rating. This size used primarily to enclose multiple insulation wires in heat and abrasion resistant covering.

Stainless Steel Braid

Stainless steel over braid is most commonly specified in applications where leads may be subjected to abrasion due to movement of the application. Lead wires may be rubbing together or passing over sharp objects.

Stainless Steel Armor

Used over leads in areas where more protection is necessary. Selected for similar applications as the stainless steel braid, in addition to applications where non-fluid contamination may come in contact with the leads. This lead protection is not as flexible as the braid.

Stainless steel square lock construction.

Convoluted Armor

This is a seamless product and can be attached to the heater so that fluids do not contaminate the leads. This system of lead protection is generally associated with the “Sealed Band” construction. Not recommended where leads are flexed in the application.

Screw Terminals

Screw Terminals

Terminals are a very convenient way of connecting our band heaters to power; typically, Monel® lugs are used to secure wiring. Supplied when heater width is at a minimum or when, in application, a buss bar is used to connect the terminals of adjoining heaters.

Customer to specify type, part number and amperage required. There is a wide variety of Hubbell® plugs that can be fitted to our heaters. Please specify Hubbell's part number or call us for suggestions.

Strap Standards

Straps can be vastly modified to fit a wide variety of bands. As wider bands are used, multiple straps will most likely be designed in. Normally barrel nuts are built into the ends: one threaded, one through hole. Slots shown are to clear termination areas. Unless otherwise specified, straps are assigned by our engineering staff to best suit each application.

Illustrated are the various available styles of clamping for band heaters. When a band is provided the material is of a low coefficient of expansion type. Width of the clamping band or the number used per heater is dictated by the design standards. There are a variety of clamping mechanisms that can be attached to the band or directly to the heater. The most common forms are the strap and strap ends. Factors influencing the type and size of clamping are:

  • Type of band heater
  • Diameter and Width
  • Termination type and location
  • Holes and notches in heater
  • Preferences of the user

 

Belleville Clamping

Belleville Clamping

A clamping system is generally selected for use with large diameter heaters where additional compensation of band elongation is required. Belleville clamping comes with a standard 1/4 - 20 X 5" (12.7 cm) long screw.

 

Spring Bolt Clamping

Spring Bolt Clamping

Spring bolt clamping applies constant tension on the clamping mechanism to compensate for heater elongation once it has been energized. Spring bolt clamping comes with either a 1/4 - 20 X 4" (10.7cm) or 1/4 - 20 X 5" (12.7cm) long screw.
