Hot Wall Hat Furnace PZ up to 850 °C
Max temp: 850 °C | Volume: 60–950 l | Voltage: 400 V
Hot wall hat furnace for protective atmosphere heat treatment up to 850 °C
Need to process large or heavy charges in a defined protective atmosphere at a higher operating temperature?
The PZ hot wall hat furnace up to 850 °C is designed for heat treatment processes where bottom loading, floor-level manipulation, protective atmosphere and uniform temperature distribution are essential.
- You need heat treatment up to 850 °C
- You process charges under a defined protective atmosphere
- You work with argon, nitrogen, forming gas or similar process gases
- You need to load and manipulate the charge at floor level
- You want to avoid structural modifications to the hall floor
- You need a higher operating range than the 650 °C version
Key features:
- Maximum temperature 850 °C
- Recommended operating range 300–800 °C
- Bottom-loading hat furnace design
- Gastight retort for defined protective atmosphere processing
- Forced circulation of protective atmosphere
- Water-cooled circulation fan
- Electrically lifted chamber
- Automatic intake of protective atmosphere for one gas type
Typical applications
The PZ furnace is suitable for heat treatment processes where the charge surface must be protected from oxidation or unwanted changes during heating.
- Tempering
- High-temperature tempering
- Tempering of tool steels in a protective atmosphere
- Tempering after vacuum hardening
- Normalising annealing
- Soft annealing
- Annealing for stress relieving
- Recrystallisation annealing
- Artificial ageing
- Sintering
Typical industries
- Heat treatment shops
- Tool manufacturing
- Metal processing
- Mechanical engineering
- Automotive suppliers
- Research and development
Main benefits
- Floor-level loading of large or heavy charges
- Defined protective atmosphere inside the retort
- Reduced need for structural modifications to the hall floor
- Uniform heating thanks to protective atmosphere circulation
- Higher operating range than the 650 °C version
For lower-temperature processes, consider the PZ hot wall hat furnace up to 650 °C.
