Carbolite 3-Zone Large Tube Furnaces TZF TZF-12-38-850 1200℃

The CTF single zone and TZF 3-zone wire wound tube furnaces use a wire element that is wound directly onto a fixed diameter integral ceramic work tube.

This simple and economical design of both the CTF and TZF provides a tube furnace that can be used without the need to purchase an additional work tube.

However,should vacuum or a modified atmosphere be required,it is necessary to use a separate additional 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.

The TZF 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 for temperature and compensate for the loss of heat from the tube furnace ends.The use of an additional slide-in work tube protects the integral work tube for the TZF and heating element.
