Forced convection chamber furnace with front loading up to 850 °C
Need to treat large charges evenly with precise temperature distribution and a dynamic temperature curve?
The KNC/H forced convection chamber furnace up to 850 °C is designed for industrial processes where uniform heating, forced air circulation and robust construction are essential.
When is this furnace the right choice?
- You need heat treatment up to 850 °C
- You require forced air circulation
- You process larger batches or bulky charges
- You need precise temperature distribution in a front loading chamber
- You work with tempering, ageing, annealing, curing or preheating
- You need a furnace with upward door opening
The KNC/H furnace is suitable for heat treatment under normal atmosphere where the quality of the result depends on even heat transfer throughout the charge. The horizontal forced air circulation system, together with a powerful fan, supports stable and repeatable process conditions inside the chamber.
Key features:
- Maximum temperature 850 °C
- Recommended operating range 300–800 °C
- Horizontal forced air circulation
- Resistance heating with meanders
- Insulation made of mineral-fibre blocks and lightweight refractory bricks
- Available chamber volumes: 1000, 1500 and 2000 L
- Maximum bottom load capacity up to 1500 kg
- Ht205 controller with 30 programmes of 15 steps each
- Type K thermocouple
- Solid state switching relays for safe furnace opening
- Limit unit
- Manually controlled suction and ventilation flap
Typical applications
The KNC/H furnace is suitable for industrial heat treatment under normal atmosphere, especially where uniform heating and forced air circulation are important for repeatable results.
- Normalisation annealing
- Annealing of non-ferrous metals
- Soft annealing
- Recrystallisation annealing
- Low-temperature tempering
- High-temperature tempering
- Curing
- Preheating
Typical industries
- Heat treatment shops
- Foundries
- Automotive industry
- Metalworking
- Tool manufacturing
- Industrial production with aluminium and non-ferrous metal processing
Main benefits
- Even temperature distribution in the working chamber
- Better temperature uniformity thanks to forced air circulation
- Dynamic temperature curve during heating and cooling
- Better repeatability between batches
- Improved process stability for demanding heat treatment operations
- Higher temperature flexibility than the 650 °C version
- Robust construction for industrial use
- Suitable for large industrial charges
- Custom adjustments according to the process
Suitable for customers who need a large front loading chamber furnace with forced air circulation for precise and repeatable heat treatment up to 850 °C.
For lower-temperature processes, consider the KNC/H 650 °C forced convection chamber furnace. If you need top loading, consider the KNC/V 850 °C forced convection chamber furnace. For large and heavy batches loaded on a bogie hearth, consider the VKNC 850 °C forced convection bogie hearth furnace.
