Product Details

We manufacture Mica Band heaters with or without outer heat saving insulation covers in various sheathing materials, viz., S.S, Brass, MS, depending upon applications which provides the best combination of physical strength, high emissivity & good thermal conductivity to heat cylindrical parts, good for sheath temperature upto 400 degree C.

For maximum connecting surface and protect exposed terminals, a specially designed steel box is affixed on the heater, where the terminal wires are securely fastened to an assuming positive contact with the windings, providing max. amperage carrying capacity.

一个特定的测量镍铬电阻丝带wire is properly engineered to achieve the lowest winding temperature possible, resulting in maximum heater life. The ribbon wire is evenly spaced wound on specially selected mica strip providing even heat distribution, thus eliminating hot spotting that can cause premature heater failure.

Specially selected mica grade & thickness is used to insulate windings providing excellent thermal conductivity & dielectric strength.
These heaters are available in various lead terminations & clamping variations.

For minimum heat loss band heaters are also specially made as per customers specification with heat saving insulated cover on the outer surface of the heater.

Terminal Connection
- 2 Pin Male Plug - 16Amps
- SS 304 Terminal Box with Screw Post Terminals and 10" Long Cable
- Screw Post Terminals with Ceramic Protection Caps
- Metal Braided Leads Exit through edges on both sides of gap

Electric Terminal Connections for Band Heaters will be Provided with SS protection caps at center of width either at 180 Deg opposite the Clamping or 90 deg from Clamping, unless specified

All Band Heaters above Dia 60mm will be provided with Screw Stud Electric terminal connections covered with SS Protection Caps

All Mica Band Heaters Below 60mm Dia will not have Screw Post 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.

Note: 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.

All Thermocouple Holes for Band Heaters (if required) will be Provided at center of width either at 180 Deg opposite the Clamping or 90 deg from Clamping, unless specified along with drawing.

Two Piece Construction: Available on any screw or lead termination or clamping variation. Used on large cylinders or where heaters cannot be slipped over end of cylinders. Two piece Band Heaters are normally rated at half total wattage and full line voltage.

Limitations: Min. I.D. : 3" Min. Width: 1½"
