Product Description

The NACTZF 3-zone high temperature tube furnaces are available at 1500 °C, 1600 °C, 1700 °C and 1800 °C 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.
