Holding Furnace PTE Mk.II up to 900 °C
Max temp: 900 °C | Capacity: 105–1250 kg Al | Voltage: 400 V
Electric holding furnace for aluminium alloys up to 900 °C
Need to keep molten aluminium ready for casting while reducing energy consumption, heat loss and installation space?
The PTE Mk.II holding furnace up to 900 °C is designed for foundries that need stable aluminium holding, low operating costs, compact dimensions and reliable crucible heating.
- You need to hold aluminium or aluminium alloys at casting temperature
- You require a holding furnace with chamber temperature up to 900 °C
- You want to reduce energy consumption during long holding cycles
- You have limited installation space in the foundry
- You need easy replacement of both crucible and heating elements
- You want a stationary furnace with the option to convert to a transport version
Key features:
- Maximum furnace chamber temperature 900 °C
- Maximum temperature for long-term operation 800 °C
- Recommended operating range in crucible 650–850 °C
- Electric resistance heating
- Holding of aluminium and aluminium alloys
- Octagonal furnace design
- Emergency drain at the bottom of the furnace
- Available aluminium capacity from approx. 105 to 1250 kg
Typical applications
The PTE Mk.II furnace is designed mainly for holding molten aluminium at a stable temperature before casting. It is suitable where melting and casting are separated or where a reliable buffer of molten aluminium is needed near the casting workplace.
- Holding of aluminium and aluminium alloys
- Temperature stabilisation of molten aluminium before casting
- Buffer furnace for casting workplaces
- Support furnace for die-casting operations
- Small and medium aluminium casting operations
- Melting of aluminium and aluminium alloys when required by the process
Typical industries
- Aluminium foundries
- Non-ferrous metal casting plants
- Die-casting operations
- Automotive suppliers
- Mechanical engineering
- Toolmaking and mould production
- Maintenance and repair foundries
Main benefits
- Low operating costs during holding
- Energy-efficient furnace design
- Stable melt temperature
- Easy replacement of crucible and heating elements
- Emergency drain for increased process safety
For applications requiring regular melting and holding in one furnace, consider the PT Mk.II electric melting furnace. If transport of molten aluminium is required, consider the PTT transport holding furnace.
