These furnaces are top loading
and particularly suited for applications involving tall crucibles and
heavy components.
The coiled resistance wire elements are embedded in
robust panels of cast refractory and line the four sides of the chamber
ensuring even heat transfer to the load. Elements are not placed in
the bottom of the chamber where they may be damaged by spillage. The
elements are easily replaced by removal from the top of the furnace.
The door contains a simple vent to help remove fumes
from the chamber.
The temperature controller is recessed into the furnace
housing - and is inclined upward ensuring the display is clearly visible.
Push button operation allows precise, repeatable setting and the digital
display gives a clear indication of both actual furnace temperature
and set-point.
The platinum/platinum 13% Rh Type R thermocouple gives
a stable output over a long life and is located in a protective ceramic
sheaf in a corner of the chamber where it is unlikely to be accidentally
damaged.
Chamber sizes are 5, 10, 23 and 100 litres, with a
maximum temperature of 1200°C.
