Yaran's high temperature tube furnaces can be designed for horizontal or vertical positions with working temperatures of up to 1800 °C. However, for special applications, the temperatures up to 2200 °C with Graphitic heating elements and insulators are pertinent.
The high grade insulation materials consist of vacuum formed fiber plates and guarantee low energy consumption and high heating rates, due to their low thermal conductivity.
The programmable PID temperature controller enables programming up to 8, 10 or 30 step of heating, soaking and cooling. PC programming software is also available for JUMO controllers (Germany).
Several options like multiple heating zones, rotary tubes, gas mixing and low or high vacuum pumps are available.
The main features which expand the application of such furnaces is a clean and highly controllable heating zone which could be used at different atmospheres from high vacuum to positive pressure of inert, reducing or even oxidizing gases.
