Product Description

The NACTZF horizontal 3-zone tube furnace range uses a wire element that is wound directly onto a fixed integral ceramic work tube.

The heated length is divided into 3 zones. 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.

This design provides a furnace which can be used without the need to purchase an accessory work tube. However, should vacuum or a modified atmosphere be required, it is necessary to use a separate slide-in work tube in order to provide the required length needed to fit end seals. Similarly, in some circumstances a work tube that has different physical or chemical properties to the fixed work tube may be required.

Standard Features

  • 1200°C maximum operating temperature
  • Provides a longer uniform zone than can be achieved in a single zone tube furnace
