High Temperature Tube Furnace - STF 15 / TZF 15

Close

Language:

The Carbolite Gero STF single zone and TZF 3-zone high temperature tube furnace range is available at 1500 °C and 1600 °C with both models using silicon carbide heating elements.

This range of tube furnaces does not include an integral work tube and one must be selected as an additional item. The work tube length is dependent on the application eg for use with modified atmosphere or vacuum.

The TZF 3-zone high temperature tube furnace has heated lengths of 450 and 610 mm. An extended uniform zone in the mid-section of the work tube is achieved with the use of end zone controllers which track the centre zone temperature and compensate for the loss of heat from the tube ends.

Standard features

  • 1500°C & 1600°C maximum operating temperatures
  • Carbolite Gero 301 controller, with single ramp to set-point & process timer
  • Accepts work tubes up to 60 or 90 mm outer diameter depending on model
