N 15/65HA, N 30/45HA - N 500/85HA
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.

• Tmax 450 °C, 650 °C, or 850 °C
• 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)
• Switchgear with solid-state relays
