The construction, coupled with the high watt density capabilities, make the MI Band the obvious choice for the most severe band heater applications. Industries include:
- Plastics Industry
- Scientific, laboratory, and testing equipment
Flexible Leads, Near Gap
Available with leads exiting axially or along the width of the band. Axial leads can be positioned on each side of the gap. Axial leads feature full contact clamping for longer heater life. 10" (25.4 cm) leads standard, other lengths available.
Flexible Leads, Near Gap, With Cap
Low profile cap and tube with leads exiting axially, 90° to axis, or at a specified 15°, 30°, or 45° from axis. Axial leads exit in direction of junction/termination. If heaters are in tandem, they can be positioned next to one another. 90 degree cap ideal for installations where access is limited. 10" (25.4 cm) leads standard, other lengths available.
Two Piece Band
Specify for easy installation/removal where projections or tandem positioned heaters are in use.
When using two-piece heaters, each half is designed with half of the total wattage requirement. This has the capability of being used on either 120 Volte (V1 = V2 = V Total) when connected in parallel or 240 Volts (V1 + V2 = V total) when connected in series.
A ground wire is available on most heaters where grounding is required.
Additional Lead Options
Flexible Leads, Opposite Gap
Available with leads exiting axially or along the width of the band. Axial leads can be bound together in one braided sheath. These heaters are generally specified when clearance around the heater is not adequate to allow the lead to exit from the heater pressure plate. 10" (25.4 cm)leads standard, other lengths available.
Flexible Leads, Opposite Gap, with Cap
The cap and tube option gives protection near the sheath. Leads can exit axially, 90° to the axis, or at a specified 15°, 30° or 45° from the axis. 10" (25.4 cm)lead standard. Other lengths available.
Screw Terminals Near Gap
Screw terminals can be positioned near the gap on each side, along the width, or along the length. This style of terminal helps simplify lead wire connections.
Screw Terminals Opposite Gap
Screw terminals can also be positioned opposite the gap either along the width or along the length.
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.
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.
Standard Terminal Box
Designed for protection safety, snap-off cover leaves terminals easily accessible.
For heaters 1 1/2" (38.1 mm) or wider with screw terminals at one end along length on top. Also with screw terminals at one end across width, on top 2 5/8" (67.0 mm) or wider.
Terminal cover protects terminals against accidental grounding or short circuit due to spillage.
European Plug Options
Plug is illustrated in the most common position. There are occasions for special boxes where the plug may be positioned on the top surface of the box.
Other Plug Options
Quick Disconnect Socket
2 pole-25 amp-250V 600° F (315.5° C) service. Ideal for power connection to heaters. Durable cast aluminum body on female side. Both sides have ceramic insert insulators. Ground connection via contact fingers.
Hubbell® Plug (or equivalent)
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.
Special with Holes
Heaters can be built to satisfy your special requirements. Certain applications require holes for thermocouples, to clear tubing, wiring, and other obstacles. These modifications require customer drawings to specify exact diameters and locations of the holes. Special order only.
Special with Cutout
When clearance is a problem with band heater installation, consider requesting slot cut-outs. This can greatly facilitate installation. Drawing is required with exact dimensions and locations. Special order only.
Design allows the heater to be expanded and thus heat from an internal surface. Available in a variety of clamping styles (please indicate when ordering; shown is the wedge lock low profile clamping). Constructed with a fully notched case.
Features a notch on the case to facilitate opening. Available in a wide variety of termination styles. Standard notch size is 1/8" (3.1 mm).
Fully Notched Band
Used not only in circular applications but can be adapted for irregular surfaces. Available in a wide variety of termination styles.
Specify inside dimensions, width dimensions and clamping ears. Available in a variety of termination styles and two location choices for clamping ears.
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
