Electric Terminal Connections for Band Heaters will be Provided with Chrome Nickel Steel protection caps at center of width either at 1800 opposite the Clamping or 900 from Clamping, unless specified. All Band Heaters above Dia 60mm will be provided with Screw Stud Electric terminal connections covered with Chrome Nickel Steel Protection Caps. All Mica Band Heaters Below 60mm Dia will not have Screw Post Terminals. |

| |
 |
|
Robust Clamping: Specially designed mounting brackets with Chrome Plated Allen Key bolts M-6 x 45mm are used to securely draw the heating element assembly against the cylinder evenly & tightly across its entire width, located at 180°C from the screw terminals. |

| Thermocouple Holes/‘U’ Slots/Cutout |
| |
|
| |
Normally required for clearance of the thermocouple probes or holding bolts. Oversize gap can in many cases serve the same purpose, using the centre of the gap as a starting point, specify location in terms of degrees and size of the hole or cut-out. Minimum of ½” is required from the hole to the edge of the heater. For critical hole or
cut-out locations, please provide detailed drawing.
|
|
All Thermocouple Holes for Ceramic Band Heaters (if required) will be provided at center of width either at 180° opposite the Clamping or 90° from Clamping, unless specified along with drawing. |
|
As far as possible please avoid thermocouple holes. Try and locate them in the heater gap, since holes in the heater body complicates the internal wiring resulting in less heating area and also turns out to be more expensive. |
|
| The nominal gap between the clamping is 5-10mm. If a larger gap is required for probes or thermocouples, specify when ordering. |

voltage. |
|
|
|
| The Two-Piece Ceramic Band Heater is commonly used on sizes larger than 20" diameter
or when it would be inconvenient to use a one-piece heater. It is available with all
types of insulation, construction styles, clamping or termination variations. |
Min. ID : 4" (101.6 mm)
Min. Width : 1" (25.4 mm)
Max. ID : 44" (1118 mm) |
| Larger sizes are manufactured in multiple segments. Watts and volts are specified per each half when ordering. |
