Forced Convenction Chamber Furnace PP 850 °C
Max temp: 850 °C | Volume: 20–750 l | Voltage: 230–400 V
Forced convection chamber furnace for precise heat treatment up to 850 °C
Need reliable and uniform heating for tempering, annealing, artificial ageing or heat treatment of metal parts at higher temperatures?
The PP forced convection chamber furnace up to 850 °C is designed for processes where forced air circulation, controlled temperature rise and even heat transfer into the charge are essential.
- You need heat treatment up to 850 °C
- Your process runs mainly within 300–800 °C
- You require forced horizontal air circulation
- You need uniform heating of tools, components or test samples
- You process metals in industrial, workshop or laboratory conditions
- You want optional forced cooling or protective atmosphere supply
Key features:
- Maximum temperature 850 °C
- Recommended operating range 300–800 °C
- Forced horizontal air circulation
- Refractory internal chamber lining
- Refractory circulation inserts on the sides and back
- Available chamber volumes from approx. 20 to 750 L
- Ht205 controller with 30 programmes of 15 steps each
- Manual ventilation flap for chamber cooling
- Low-noise operation with contactless switching relay
Typical applications
The PP furnace is suitable for industrial heat treatment processes under normal atmosphere, especially where temperature uniformity and controlled heat transfer are important for the final quality of the charge.
- High-temperature tempering
- Low-temperature tempering
- Tempering of tool steels with protective atmosphere (semi-gastight version)
- Annealing
- Solution annealing
- Annealing for stress relieving
- Soft annealing
- Recrystallisation annealing
- Heat treatment of metal materials
- Artificial ageing
- Heating and drying
- Preheating
- Material testing
- Curing
- Enamel firing
Typical industries
- Heat treatment shops
- Tool manufacturing
- Metal processing
- Automotive industry
- Mechanical engineering
- Testing laboratories
- Research and development
Main benefits
- Even temperature distribution thanks to forced air circulation
- Good heat transfer into the charge
- Reliable repeatability of heat treatment processes
- Low-noise operation
- Suitable for industrial, workshop and laboratory use
For processes up to 650 °C, consider the PP 650 °C forced convection chamber furnace. For additive manufacturing applications, consider the PP furnace for additive manufacturing.
Optional accessories available at additional cost
- Ht200 controller (30 programmes with 25 steps each, USB interface)
- Protective atmosphere supply (manually or automatically controlled gas intake)
- Semi-gastight furnace version (cannot be combined with the automatic ventilation flap)
- Three-channel digital temperature recorder
- Automatic ventilation flap for cooling the furnace’s operational space
- Optimisation of the temperature field for compliance with DIN 17052-1 ΔT 10 °C in the internal usable space (in an empty furnace at Tmax, a grommet for thermocouples is required)
- Measuring loop calibration
- EIA-485 or LAN interface
- HtMonit EV set (contains software + interface)
- Controlled overpressure forced cooling (cannot be combined with the semi-gastight furnace version)
- Uncontrolled overpressure forced cooling (cannot be combined with the semi-gastight furnace version)
