Galvanising furnace

The galvanising furnace is the core of the galvanising plant. It heats the zinc bath in which the pieces  are immersed and coated with a corrosion protection layer.

  • Customised for steel kettles of any size
  • Proven flat-flame and high-velocity burners combined with state-of-the-art control technology
  • Demand-oriented output control of the burners through speed control of the fans
  • Robust and durable construction
  • Modular design for shipping with containers for overseas projects
  • Selection of high-quality insulation to increase energy efficiency
  • Optimum thermal efficiency through pressure control in the furnace
  • Short assembly times due to extensive pre-assembly
  • Optionally equipped with a rail system, or removable front panel, for easy and quick kettle replacement

The enclosure is a closed unit located above the galvanising furnace and protects the employees from emissions and zinc splashes.

  • In combination with a powerful filter system, all emissions can be captured and the ambient air  can be kept clean.
  • Designed to the highest safety standards to protect workers
  • Robust construction and use of double-glazed viewing windows
  • High degree of automation possible through communication with the conveyor system
  • Optionally available as a mobile enclosure to make kettle changes faster
  • Optionally available with additional blow-off devices to further reduce emissions in the employees‘ working area


The dryer is a closed housing in which the material coming from the pre-treatment baths is dried. From the dryer, the material is fed directly to the galvanising furnace.

  • Different variants, tailor-made for the respective hall layout and material flow
  • Continuous dryer with transport device
  • Chamber dryer without transport device
  • Directly or indirectly heated
  • Increased energy efficiency through humidity control and use of speed-controlled fans
  • Use of state-of-the-art control technology for fully automatic operation
  • Optimum flow of the material to be dried through individual routing of the dry air pipes
  • Durability of all components through consistent use of acid-resistant materials and coatings
  • Optionally available with integrated heat recovery system

Heat recovery

By installing a heat recovery system, energy can be recovered from the hot exhaust gases produced by combustion in the galvanising furnace. This energy can then be used to heat the drying air or to heat the pre-treatment baths.

  • Increase of the overall efficiency to over 90%
  • Exhaust gas-air heat exchanger design
  • Exhaust gas-water heat exchanger design
  • Possibility of storing surplus heat in buffer storage tanks
  • High efficiency and fast amortisation
  • Automatic damper control of the heating circuits, depending on operating status and heat demand
  • Optional use of an intermediate water-water heat exchanger to protect the components from penetrating acid of the pre-treatment baths

Control – Visualisation

The control and visualisation system processes the signals of the most important electronic components and provides the operating states via user interface.

  • Signal exchange with adjacent subsections such as pre-treatment and conveyor technology
  • Clear representation via flow diagrams
  • Control of individual components, such as burners and fans, via PC control panel in the galvanising plant or via remote access
  • Assignment of different access rights, from reading to switching components on and off
  • Intuitive operation
  • Summary and storage of error messages in a history
  • Possibility of setting up an SMS alarm to be contacted automatically in the event of faults occurring
