The Mi-Plus is the solution for applications that require high
watt densities (Watt/in2) and/or high operating temperatures.
Mi-Plus band heaters are capable of temperatures up to
760°C (1400°F) and watt densities up to 23.25 Watt/cm2
(150 Watt/in2). The recommended maximum watt density for
a specific application will depend on the heater size and its
operating temperature.
Specially formulated mineral insulated tape providing
excellent thermal conductivity and dielectric strength is
used to insulate the nickel chrome resistance wire from the
stainless steel sheath. The heater assembly is formed under
pressure to a precise diameter with a thin low-mass cross
section, assuring fast heat-up rates and reduced cycle times.
Specifications and Tolerances
If non-standard widths or tighter tolerances are required, contact OMEGA. Performance Ratings Maximum Temperature: 760°C (1400°F) Nominal Watt Density: Nozzle Bands, Under 3" Diameter: 4.7 to 15.5 Watt/cm² (30 to 100 Watt/in²) Barrel Bands, 3" and Greater in Diameter: 3.1 to 10.9 Watt/cm² (20 to 70 Watt/in²) Maximum Watt Density: 23 Watt/cm² (150 Watt/in²) dependent on heater size, operating temperature and termination Electrical Ratings Maximum Voltage: 480 Vac per termination Dual Voltage: Available depending on heater configuration Maximum Amperage: Lead Wire Termination: 10A Screw Terminations: 8-32UNF—20A, 10-32UNF—25A Resistance Tolerance: +10%, -5% Wattage Tolerance: +5%, -10% Physical Size Construction Limitations Nominal Gap—Built-In Bracket: Less than 44 mm (13/4") Diameter: 6 mm (1/4") 44 to 51 mm (13/4 to 2") Diameter: 8 mm (5/16") 51 to 127 mm (2 to 5") Diameter: 10 mm (3/8") 127 mm to 0.46 m (5 to 18") Diameter: 13 mm (1/2") Greater than 0.46 m (18") Diameter: 19 mm (3/4")
If a larger gap is required for probes or thermocouples, specify when ordering. Maximum Inside Diameters: One-Piece: 355.6 mm (14")* Expandable: 355.6 mm (14")* Two-Piece: 635.0 mm (25") Over 635.0 mm (25") will require multiple segments. Contact OMEGA. * Note: OMEGA recommends two-piece construction for heaters 10" ID and greater. Standard Widths: 25.4 to 203.2 mm (1 to 8") Width Tolerance: 2.4 mm (±3/32")
