The Thermic edge 2100C range of laboratory furnaces are semi-automatic with top loading graphite hot zone that heats different sample sizes up to 2100C. The atmosphere can be either vacuum or inert gas. The furnace range has been designed to be very simple to operate, while incorporating extensive safety features, and also be durable and reliable.
The furnace provides simple operation by using single buttons for PUMP – VENT – GAS ON – GAS OFF. Thermal control is via the RKC or Eurotherm programmable PID temperature controllers, which can be programmed from the front panel or by connecting to a laptop or PC. The controllers can store thermal recipes and log data from each run.
The automated pump down sequence includes a number of pump and purge cycles, to remove residual oxygen (which can damage the hot zone by oxidation above 500C). This greatly increases the life of the graphite hot zone, and enables the furnace to run well on just a rotary pump, without the need for a second high vacuum pump.
The system consists of a vacuum chamber mounted in a wheeled frame. The vacuum chamber is flush with the work top, to allow easy access to hot zone. A PLC is integrated in the frame to control the heating sequence, the pumping process, venting, gas admission and interlocks. The interlocked electric lid lift ensures the furnace cannot be opened if the hot zone temperature is too high. Red / Green LED’s on the front of the furnace show the state of all of the furnace safety interlocks.
