Carbolite Gero TF1, TF3 Tube Furnaces, maximum temperature 1600°C

TF tube furnaces achieve first-class performance with low power consumption and low case temperature due to the use of high-quality heating elements and thermal insulation design. Maximum temperature of 1600 °C is available.

The range includes small and medium case sizes and two heated lengths in each size. The TF1 are single-zone furnaces, and the TF3 are three-zone furnaces which further extend the uniform heated length.

Work tubes with outside diameters of 60 mm and 100 mm can be fitted. The use of an accessory slide-in work tube protects the heating element and is required to support the workpiece.

3-zone TF3 furnaces provide excellent temperature uniformity resulting from division of the heated length into 3-zones with its own controller and thermocouple. Should vacuum or a modified atmosphere be required, it is necessary to use a slide-in work tube of adequate length needed to fit end seals. In some circumstances, a work tube that has different physical or chemical properties may be required.

The benefit of this design is its flexibility; with the use of tube adapters, the same furnace can be used with a variety of tube diameters.
