Cold wall retort furnaces up to 2400 /°C or up to 3000 /°C

SVHT 2/24-W - SVHT 9/30-GR
Compared with the VHT models, the furnaces 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 can be implemented with models of the SVHT..-W product line. Models of the 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.

• Standard sizes with a furnace chamber of 2 or 9 liters
• Designed as pit-type furnace, charged from above
• Frame construction with inserted sheets of textured stainless steel
• Double-walled water-cooled stainless steel container
• Manual operation of process gas and vacuum functions
• Manual gas supply for non-combustible process gas
• A step in front of the furnace for an ergonomic charging height
