|Models PTF 12, 15 and 16
- Max Temperature: 1200°C, 1500°C and 1600°C
- For units at 1200°C, heating is by a resistance wire element wound on to the ceramic work tube which is an integral part of the furnace.
- At 1500°C and
1600°C, silicon carbide rod elements are mounted parallel to the tube.
- The end zone controllers are coupled to a centre zone thermocouple enabling the centre zone temperatures to be closely linked.
This system provides a longer uniform zone temperature than that achieved by the use of single zone furnace of the same length.
Independent control of each zone is also available.
