Hot Wall Retort Chamber Furnace (with circulation) PKRC up to 950 °C
Max temp: 950 °C | Volume: 24–225 l | Voltage: 400 V
Hot wall retort chamber furnace with circulation for protective atmosphere heat treatment up to 950 °C
Need to process metal parts in a defined protective atmosphere while maintaining better temperature uniformity inside the retort?
The PKRC hot wall retort chamber furnace with circulation up to 950 °C is designed for protective atmosphere heat treatment where a gastight retort and circulation of the internal atmosphere are required.
For applications requiring higher temperatures, the furnace can also be equipped with an optional Inconel retort and cast-iron propeller, allowing operation up to 1100 °C.
- 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 uniformity inside the retort
- You need heat treatment up to 950 °C
- You work with argon, nitrogen, forming gas or similar process gases
Key features:
- Maximum temperature up to 950 °C
- Recommended operating range 700–900 °C
- Gastight retort for controlled atmosphere processing
- Internal 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 uniformity 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 uniformity thanks to internal atmosphere circulation
- Reduced oxidation of surface-sensitive parts
- Low protective gas consumption
- Uniform heating of the charge inside the retort
If circulation is not required, consider the PKR hot wall retort chamber furnace without circulation.
Optional accessories available at additional cost
