GENERAL DESCRIPTION:
Constructed using a robust casing for bench mounting. A ventilated double skin construction ensures that the furnace casing remains relatively cool.
The furnace lining consists of high efficiency graded low thermal mass insulation to reduce heat losses and enhance a uniform working zone. A recrystallised alumina work tube (open both ends) can be supplied for use with the furnace, and this is supported at each end by hardened fibre insulation.
Heating: The heating elements are molybdenum disilicide U shaped elements mounted vertically in cavities symmetrically positioned at each side of the work tube. The elements are on low voltage, provided by an integral transformer within the oven casing, and power switching is by means of thyristors for accuracy and reliability.
Controls: The controls are on one side and below the furnace body for ease of vision. A microprocessor based digital temperature controller with set-point and process displays, provides accurate fully automatic control with a variable ramp to temperature rate control. An adjustable independent digital over-temperature protection controller is fitted as standard. Controls include thermocouple break protection.
Other sizes and 1800°C versions, as well as multi-tube and split tube furnaces can be made to order. Vertical and single open ended tube furnaces are also available.
