Tempco mineral insulated band heater provides excellent thermal conductivity and dielectric strength is used to insulate the nickel chrome resistance wire from the stainless steel sheath. The heater construction is formed under pressure to distinct diameters with a thin low-mass cross section, assuring fast heat-up rates and reduced cycle times.
Additionally the Tempco Mineral Insulated Band Heater has many available termination options including type W1, type W2, type L1, type R2, type R1, Type W5.
Type W1: Straight lead wire braid leads
Type W2: Right-angle wire braid leads, parallel to heat
Type L1: Plain wire leads
Type R2: Right-angle armor cable
Type R1: Straight armor cable
Type W5: Right-angle wire braid leads, 90 degrees to heaters
Mineral Insulated Band Heater Construction
Tempco Mineral insulated band heaters provide great solutions for high watt density operating temperatures and applications. Furthermore these heaters have capability to provide temperature up to 1400 degrees Fahrenheit and watt densities up to 150W per squared inch. The size of the band heater with will determine the watt density and it operating temperatures. Many sizing options are available to meet the needs of your specific application. Also Tempco provides very durable power screw terminals that are unique to their manufacturing. These screws are constructed from stainless steel and are resistant to over-torqueing. In addition the clamping mechanism for these band heaters is a strong one piece construction that is built into the heater. The power of the clamp is attested to the nuts and socket head screws, which provides the superior clamping force for maximum performance.
