MI Band

The MI Band is a high performanceheater. Its performance and name are derived from Watlow’s exclusive mineral insulation—a material that has much higher thermal conductivity than the mica and hard ceramic insulators used in conventional heaters.A thin layer of the “high” thermalconductive MI material is used to electrically insulate the element wire from the inside diameter of the heater sheath. A thicker, “low” thermal conductivity layer backs up the element wire, directing the heat inward towards the part that is being heated. The result is more efficient heat transfer...a performance solution that lowers element wire temper- atures and increases heater life.
Thick LowConductivityMI BackingCoiled or SinuatedWire Element Performance Capabilities •Heater operating temperatures to760°C (1400°F) •Watt densities to 35.6 W/cm
2 Permanently attached clampbars (230 W/in
2) available on smalldiameter nozzle bands•Watt densities to 15.5 W/cm Stainless steel cover as well as side fold design eliminate cumbersomeclamping straps, which makes installation easier. resistcontamination by overflow of plastic or other free-flowing materials. Side folds turn to the inside diameter rather than the outside diameter.•
