TZF Series, Wire Wound Horizontal Three Zone Tube
Furnaces, 1200°C
TZF 12/75/700/3216P1
Comprising an horizontal furnace body with three
zone wire wound worktube element that is equipped
as standard with “Back to Back” zone control. It can
be used directly or with accessory worktubes.
Features:
●
1200°C maximum operating temperature
●
Excellent uniformity results from division of the heated
length into 3 equal zones each with its own controller &
thermocouple.
●
Provides a longer uniform zone than can be achieved in
single zone tube furnace
●
Power to the end zones is automatically adjusted to
compensate for heat loss
●
All three zones are controlled to the same set-point
●
Heated lengths of 400, 550, 700 or 900mm
●
Models accepting worktubes with outer diameters of
38mm to 90mm
●
Horizontally mounted on control module base.
L-stand:

use
Options:
●
Shorter end zone option to provide extended uniform
length (optionally in 2 phase configuration)
●
Insulation plugs & radiation shields to prevent heat loss &
improve uniformity
●
Gas injection & vacuum compatible worktube end seal
assemblies
●
Separate control module on 2 metre or 6 metre conduit
●
‘L’ style flexible stand option for vertical or independent
mounting
●
8 or 20 segment programmer
●
‘Retransmission of Setpoint’ zone control configuration for
programmed cooling
●
RS232 communications & graphical recorders
●
Alternative furnace sizes can be supplied upon request.

Single
Single, 3 phase Single, 3 phase Single or Universal
“Universal” models are easily altered between single phase (220V), 3 phase-neutral (e.g. 380/220V) and delta
(e.g. 220V) electrical supplies.
Continuous operating temperature is 100°C below maximum temperature.
Holding power is measured at the continuous operating temperature.
Uniform length measured with end plugs fitted.
