Carbolite Gero TF1, TF3 Tube Furnaces with maximum temperatures ranging from 1100°C and 1200°C

The TF tube furnace range incorporates high-quality heating elements and innovative thermal insulation design to achieve first-class performance delivering both reduced case temperatures and power consumption.

The extensive range features three main case sizes, mini, small, and medium, with multiple heated lengths available. Standard models can be configured to function with a single heated zone (TF1) or three heated zones (TF3) to extend the uniform heated length. Each heated zone of the TF3 benefits from its own dedicated controller and thermocouple.

A slide-in accessory work tube is required to protect the heating elements and support the workpiece. The TF range can accommodate work tubes with outside diameters of 32 mm to 125 mm. The variety of available work tubes and the use of tube adapters allow a single furnace to accommodate a variety of tube diameters. The work tubes themselves can easily be exchanged to meet the different physical or chemical requirements of a process.

Optional work tube packages enable users to equip the TF for operation under vacuum or modified atmosphere; for such applications, an extended work tube is required.
