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 relieve internal stress in 3D-printed titanium or nickel alloy components while protecting the surface from oxidation?
The PKRC hot wall retort chamber furnace with circulation up to 950 °C is designed for protective atmosphere heat treatment of metal AM parts, especially where controlled gas atmosphere, temperature distribution and repeatable metallurgical results are required.
- You process additively manufactured metal components
- You need stress relieving of titanium or nickel alloys
- You require a defined protective atmosphere
- You need protective atmosphere circulation for better temperature distribution
- You need a gastight hot wall retort furnace up to 950 °C
- You want vacuum pump preparation and controlled gas handling
Key features:
- Maximum temperature 950 °C
- Long-term operation up to 850 °C
- Recommended operating range 700–900 °C
- Gastight retort for controlled atmosphere processing
- Protective atmosphere circulation
- Protective atmosphere inlet and vacuum pump
- Suitable for AM titanium parts processed up to approx. 800 °C
- Suitable for AM nickel alloy stress relieving around 890 °C

Typical AM platform sizes
| Platform size | Recommended furnace type |
|---|---|
| 200 × 200 mm | PKRC 55/95 |
| 300 × 300 mm | PKRC 180/95 |
| 300 × 500 mm | PKRC 350/95 |
| 400 × 400 mm | PKRC 350/95 |
| 400 × 800 mm | PKRC 350/95 |
Main benefits
- Defined protective atmosphere inside the retort
- Better temperature distribution thanks to protective atmosphere circulation
- Reduced oxidation of sensitive metal AM components
- Repeatable stress relieving of titanium and nickel alloy parts
- Vacuum pump for atmosphere extraction before gas intake
If circulation is not required, consider the PKR hot wall retort chamber furnace without circulation.
Optional accessories available at additional cost
- Spare retort of refractory steel
- Vacuum pump for extraction of the atmosphere + necessary controlled forced cooling
- Charge thermocouple and Ht40 temperature display unit
- Controlled forced cooling (according to input cooling curve)
- Three-channel digital temperature recorder
- Optimization of the temperature field to meet DIN 17052-1 ΔT20 °C norms in the inner useable furnace (in empty furnace at Tmax)
- Calibration of the measurement loop
- EIA-485 or LAN interface
- HtMonit EV set (contains software + interface)
