Wire Wound Tube Furnaces to 1200°C
|
| 
|
The majority of these models
utilise a resistance wire heating element which is wound around the
outside of a ceramic worktube making it an integral part of the heating
element. If the tube is required to contain an atmosphere or is likely
to be contaminated by spillage, a separate work tube should be used.
The thermocouple is located in a protected position between the outside
of the work tube and the heating element, allowing the full work tube
diameter to be used and protecting the thermocouple from mechanical
damage.
|
| The CTF 12/--/1090 and TZF
12/--/1090 are of a different construction and use modular heating elements
of coiled wire embedded in moulded ceramic fibre cylinders. These elements
do not touch the tube allowing it to be replaced or alternatively allow
the use of a heat resisting metal work tube.
