Information

: High-temperature bogie-hearth furnaces

Range of standard furnaces with a chamber volume up to 2000 l
Furnaces supplied in customised configurations to match the systems precisely to the desired processes
The bogie hearth can be removed completely from the furnace for convenient loading and unloading, and is mounted on heavy-duty castors for free movement in front of the furnace
Rugged bogie-hearth design, fully insulated with highquality fibre materials, labyrinth seal between hearth and furnace housing
Reinforced bogie hearth bottom for heavy loads
Double-walled furnace housing with forced cooling, hence very low outer-wall temperatures
Furnace insulation made of high-quality aluminium oxide fibre materials with low thermal mass, rapid heating and cooling possible; exhaust openings in furnace roof
Reinforced bottom for heavy batches
Heated by high-quality MoSi₂ heating elements
The furnaces are heated by the side walls. Additional heating by the rear wall is available as optional extra.
Cutting-edge switching and control system, thyristorcontrolled heating elements, high-precision furnace regulation, wear-free, noiseless

Additional equipment:

Lifting door
Instead of hinged doors, furnaces can also be fitted with space-saving, vertical lifting doors. Electric or hydraulic drive units are available. The hot side of the insulation faces away from the operator
Rail-bound bogie hearth
Bogie hearth with steel wheels on rails, for ease of movement even with large batch weights
Transverse shunting device
Customised transverse shunting device in front of the furnace, with parking rails beside the furnace
Additional door on the rear furnace wall
for operation with two bogies
Start-up switch
The start-up switch ensures that heat-up is slow in the lower temperature range up to 250 °C, in the case of sensitive components that may not be heated up too fast.
Fully automatic furnace regulation
Exhaust flaps
Exhaust hoods
Air preheating for debinding processes
Customised furnace furniture

: Bogie hearth drive unit

Bogie hearth drive unit
Electrical chain drive for easy movement of rail-bound bogie hearths carrying heavy loads, and when opening the furnace while hot

: Heated from three sides

Heated from three sides
The standard heating elements along the side walls can be supplemented with additional heating elements on the rear furnace wall.

: Cooling fan

Cooling fan
For better ventilation of the furnace chamber and for reducing cycle times. Fan is operated automatically by the controller, fan speed can be pre-selected segment-wise.

: Exhaust air purification systems

Exhaust air purification systems
Add-on for furnace systems, with catalytic or thermal exhaust air purification systems as integrated unit.
