    Chamber furnace for hardening, annealing and preheating up to 1280 °C

    Need an industrial furnace for hardening, annealing, cementing or preheating metal charges under repeatable conditions?

    The PK chamber furnace up to 1280 °C is designed for heat treatment processes where high temperature, three-side heating, protected heating elements and practical handling of heavier charges are required.

    When is this furnace the right choice?
    • You process metal parts, tools, moulds or castings
    • You need heat treatment up to 1280 °C
    • You require hardening, annealing, normalising or cementing
    • You work with heavier charges and need practical loading support
    • You need heating elements protected against mechanical damage
    • You may require a semi-gastight version for partial protective atmosphere use
    The PK furnace is designed for industrial heat treatment where the chamber must withstand demanding thermal and mechanical conditions. Heating from three sides supports stable temperature conditions, while SiC side covering plates help protect the heating elements during loading and unloading.

    Key features:

    • Maximum temperature 1280 °C
    • Recommended operating range 700–1250 °C
    • Chamber volumes from 55 to 1400 L
    • Heating from three sides
    • SiC side covering plates protecting heating elements from mechanical damage
    • Rotary table for charge handling on selected models
    • Manual or electro-hydraulic door opening depending on model size
    • Optional semi-gastight design with protective atmosphere supply

    Typical applications

    • Hardening
    • Annealing
    • Normalisation annealing
    • Homogenisation annealing
    • Cementing
    • Preheating moulds
    • Preheating shell moulds
    • Preheating castings
    • Preheating moulds before forging
    • Heat treatment under a partially protective atmosphere with optional semi-gastight equipment

    Typical industries

    • Heat treatment shops
    • Toolmaking
    • Metal processing
    • Foundries and casting operations
    • Mechanical engineering
    • Forging operations

    Main benefits

    • Suitable for demanding high-temperature heat treatment
    • Heating from three sides supports uniform heat distribution
    • Heating elements protected by SiC side covering plates
    • Practical charge handling on selected models
    • Optional semi-gastight version for partial protective atmosphere use
    Suitable for customers who need a chamber furnace for hardening, annealing, cementing and preheating up to 1280 °C.

    If a furnace with electrically operated door opening is preferred, consider the PKE chamber furnace up to 1280 °C.

    Optional accessories available at additional cost

    • Protective atmosphere supply
    • Semi-gastight furnace design without gas supply (this is combined with protective atmosphere supply)
    • Optimisation of the temperature field to meet the DIN 17052-1 C10-B13 ΔT 20 °C standard in the internal usable space (in an empty furnace; measured in the range from 900 °C to 1100 °C; a grommet for thermocouples is required)
    • Measurement protocol for temperature uniformity (a grommet is needed for the TUS test)
    • Three-channel digital temperature recorder
    • Measuring loop calibration
    • EIA-485 or LAN interface
    • HtMonit EV set (contains software + interface)
    • Grommet for TUS test measuring thermocouples
    • Metal plate for the bottom (only up to temperatures of 1000 °C)
    • Non-controlled overpressure forced cooling (this cannot be combined with semi-gastight version)
    • Controlled overpressure forced cooling (this cannot be combined with semi-gastight version)
    • Set of SiC side covering plates

    Custom additional components

    • Custom stand
    • Custom controller
    • Electro-hydraulic door opening towards the top
    • Foot pedal or hand lever for door opening
    • Pneumatic door opening with foot control or manual lever
    • Operating tub for hardening in a protective atmosphere
