Performance Capabilities ã Engineered to achieve sheath temperatures up to 2050°F (1120°C) ã Up to six  independently controllable zones Features and Benefits Multiple, independently controllable zones  ã Allows process temperature uniformity not possible with any other single-sheathed heater Radiant design of heater  ã Allows for loose insertion in boiling holes and piping holesã Permits easy removal and replacement with minimal down time since it will not bind or seize in the hole Oxidized sheath  ã Provides high emissivity and improves the heater’s performance as oxidation increases Individual metal-sheathed coils swaged into a larger, high-temperature alloy outer sheath  ã Provides maximum protection against element burnout through the outer sheath Quick disconnect plug and jack  ã Permits fast replacement of individual elements while the press stays at operating temperature Special bending capabilities  ã Solves unusual machinery needs and keeps leads away from heated zones Flexible leads up to 842°F (450°C) ã Protects termination from high temperature environment Typical Applications ã Hot isothermal formingã Soil remediationã Hot forging diesã Heated platensã Super plastic formingã Heated platens (single and multiple zones)ã Heat treating processesã Super plastic forming with diffusion bondingã Polysilicon ingotsã Hot gas generationã Hazardous waste treatment systems Resistance WireHigh Grade MgO InsulationHigh Temperature Alloy for Outer SheathIndependently Controllable Heated ZonesCross SectionZone 1 Zone 2 Zone 3 123456 MultipleZoned PlatensNo-heat Toe EndNo-heat Section Designed for Longer Element LifePotting Cup to SealElectrical TerminationHigh-Temperature Flexible LeadsWide Range of Terminations Available  High-Temperature Heaters MULTICELL Heaters  Applications and Technical Data  WATLOW  ® 426 Definition of Terms Cold Toe:  A physical minimum requirement of 1 5  /  8  ± 5  /  16   inch Independent Zone: Up to three, separately controlled zones, which can be of varying lengths and wattages Heated Length:  The combined sum of all independent zones Wattage: Ratings are the combined sum of all independent zones      T    e    r    m     i    n    a     t     i    o    n    s No-HeatSectionIndependently ControlledZoneHeated Length ± 2%Sheath LengthColdToeIndependently ControlledZoneIndependently ControlledZoneLead Wire Length1.6 ±   5  /  16  A = 6 cell, 0.935 in. diameter, 240VAC, 3-phase B = 6 cell, 0.685 in. diameter, 240VAC, 3-phase C = 6 cell, 0.935 in. diameter, 480VAC, 3-phase Note:  Shaded area represents the Watlow offering, non-shaded area contact your Watlow representative. a  Other designs and voltages with higher temperature capabilities are available.
