Hot Wall Retort Chamber Furnace (without circulation) PKR up to 950 °C
Max temp: 950 °C | Volume: 30–230 l | Voltage: 400 V
Hot wall retort chamber furnace with circulation for protective atmosphere heat treatment up to 1100 °C
Need to process metal parts in a defined protective atmosphere at higher temperatures while maintaining better temperature distribution inside the retort?
The PKRC hot wall retort chamber furnace with circulation up to 1100 °C is designed for protective atmosphere heat treatment where a gastight retort, controlled gas atmosphere and circulation inside the retort are required.
- You need heat treatment in a defined protective atmosphere
- You require a hot wall retort furnace with circulation
- You process parts where surface oxidation must be reduced
- You need better temperature distribution inside the retort
- You need a higher temperature capability than the 950 °C version
- You work with argon, nitrogen, forming gas or similar process gases
Key features:
- Maximum temperature up to 1100 °C
- Recommended operating range 700–1000 °C
- Gastight retort for controlled atmosphere processing
- Protective atmosphere circulation
- Protective atmosphere inlet
- Vacuum pump connection inlet
- Low protective gas consumption
- Available volumes from approx. 24 to 225 L
Typical applications
The PKRC furnace is suitable for heat treatment of metallic materials in a defined protective atmosphere, especially where temperature distribution and surface protection are important.
- Protective atmosphere heat treatment
- Annealing
- Tempering
- Curing
- Internal stress relieving
- Solution annealing
- Heat treatment of tool steels with protective atmosphere
- Process development for metallic materials
Typical industries
- Heat treatment shops
- Tool manufacturing
- Metal processing
- Additive manufacturing
- Automotive suppliers
- Aerospace suppliers
- Research and development
Main benefits
- Defined protective atmosphere inside the retort
- Better temperature distribution thanks to protective atmosphere circulation
- Reduced oxidation of surface-sensitive parts
- Low protective gas consumption
- Higher temperature capability than the 950 °C configuration
For lower-temperature processes, consider the PKRC hot wall retort chamber furnace up to 950 °C. If circulation is not required, consider the PKR hot wall retort chamber furnace without circulation.
Optional accessories available at additional cost
