The very new GRF series furnaces now extend our range of production to our highest temperature limit ever, to 22000C. Furnace is operated under Argon gas environment ,based on Customer requirements. Several volumes of inner space is possible, all to be produced ‘made to measure’ pending Customer requirements. The cubical geometry of heated space with graphite heating elements placed to both sides, give a satisfactory useful space for research and small scale production, with a good life expectancy of heating elements. Insulation material is also graphite based, surrounding the heated zone with very high quality standard backup insulation at cooler layers.
