Cold Wall Retort Furnace up to 2400 C or 3000 C

HT Compared with the VHT models, the Cold Wall retort furnace of the SVHT product line offer improved performance data with regard to achievable vacuum and maximum temperature. Due to the design as pit-type furnace with tungsten heating, processes up to max 2400 °C even in high vacuum furnace can be implemented with models of the SVHT-W product line. SVHT-GR product line with graphite heating, also in pit-type design, can be operated in an inert gas atmosphere even up to max. 3000 °C.
