Fournaises tubulaires 1500°C et 1600°C
 



FEATURES
  • Maximum operating temperatures of 1500ºC or 1600ºC.
  • Available in heated lengths of 18" and 24" single zone.
  • The 24" heated length is also available in a 3 zone design.
  • Three zone tube furnaces provide a longer uniform temperature zone through elevation of end zone temperatures to compensate for normal end losses.
  • Mini design offered with 7" heated length, for use with process tubes up to 2.25" OD.
  • Furnaces incorporate low thermal mass ceramic fiber insulation for improved heat-up rates and energy efficiency.
  • Long-life free radiating silicon carbide heating elements provide excellent radial and linear chamber uniformity.
  • Power may be easily increased to heating elements from the temperature controller to compensate for SiC element resistance change (aging). This feature assures that the
    furnace’s original heat-up characteristics and maximum rated temperature is always achieved.
  • Furnaces are normally mounted horizontally on a support base or cabinet.
  • Furnace controls are built into the support base, providing convenient observation and access to all power and temperature controls.
  • Insulating end vestibules improve chamber uniformity.
  • Safety outer mesh guard provides low temperature external surface.
  • All 1500º & 1600ºC tube furnaces can be provided for optional vertical operation.
  • Vertical design is interconnected to a separate control cabinet with 6 ft. cable.
  • Three zone furnaces incorporate three separate temperature
    controls to allow variation of setpoint temperature in each zone.
  • TZF model end zone controllers may be slaved to the center zone or fully independent. (see page 44)
  • Choice of 301 or programmable controls.
