These chamber furnaces with air circulation are characterized by their extremely high temperature uniformity. Hence, they are especially suitable for processes such as cooling, crystalizing, pre-heating, curing, but also for numerous processes in tool making. Due to the modular concept, the furnaces can be adjusted to the process requirements by adding suitable equipment.

• Horizontal air circulation
• Swing door hinged on the right
• Optimum temperature uniformity (according to DIN 17052-1) up to + 4 K
• Heating from bottom, sides and top
• Optimum air flow and temperature uniformity through high circulation rates
• One shelf and rails for two additional shelves included (N 15/65 HA without removable tray)
• Air baffle box of stainless steel inside the furnace chamber for optmum air circulation
• Base frame included in the delivery, N 15/65 HA designed as table-top model (table available as an option)

For some heat treatment processes it is important to reduce the particle disposal in the furnace chamber to a minimum. To achieve highest protection for these applications these specific chamber furnaces with welded inner box and insulation fully covered with stainless steel sheets are recommended. The ovens are perfectly suitable for heat treatment processes of medical products with an emphasis on a clean surface of the product.

• Design of models N ../HA plus:
• Special sealing of the housing
• Insulation covered with stainless steel sheets
• Optimum temperature uniformity at 250 °C - 650 °C of up to + 3 K in accordance to DIN 17052-1
• Operation under protective gases as an option
