Pit-type furnaces with air circulation offer the advantage of easy charging, for heat treatment of heavy parts or loads in charge baskets. With maximum application temperatures available from 450 °C to 850 °C, these compact furnaces are particularly useful for processes such as tempering, solution annealing, artificial ageing, and soft annealing.
- Maximum temperatures of 450 °C, 650 °C, 850 °C
- Air circulation fans in the furnace bottom, high circulation rate
- Vertical air circulation with square air heating chamber
- Optimum temperature uniformity (according to DIN 17052-1) up to ΔT 4 K
- Interior walls from stainless steel
- Switchgear with solid-state relays
Additional Equipment
- Charging hoist with swivel arm and charge basket
- Integrated fan for rapid cool down or separate cooling station for retort box cooling outside of the furnace
- Retort box with protective gas inlet and outlet for production in a defined atmosphere
- Manual or automatic gas supply systems
