Recuperative gas-fired melting furnace for aluminium alloys up to 1200 °C
Need to melt aluminium alloys with high output and lower gas consumption?
The PTPR recuperative gas-fired melting furnace up to 1200 °C is designed for melting aluminium and aluminium alloys. The recuperation system uses heat from flue gases to preheat combustion air for the gas burner and helps reduce gas consumption.
When is this furnace the right choice?
- You melt aluminium or aluminium alloys regularly
- You want to reduce gas consumption in foundry operation
- You need a stationary melting furnace with high melting output
- You want lower heat losses thanks to insulation and a rotary lid
- You need reliable crucible protection
- You need to pour melt into a transport ladle or holding furnace
The recuperation system consists of a burner, heat exchanger and fan connected to the furnace frame. Hot flue gases heat the exchanger, while the fan drives fresh air through it. The burner then uses this preheated air for combustion, which helps reduce the amount of gas needed for the melting process.
Key features:
- Maximum temperature 1200 °C
- Long-term operation up to 1100 °C
- Recommended crucible operating range 650–1000 °C
- Capacity from approx. 185 to 480 kg Al
- Crucible volume from approx. 70 to 180 L
- Melting output up to approx. 270 kg Al/hour at 700 °C
- Energy consumption for melting approx. 0.7–0.8 kWh / 1 kg Al
- Recuperation system for reduced gas consumption
Typical applications
- Melting of aluminium and aluminium alloys
- Foundry melting processes
- Gas melting with reduced fuel consumption
- Pouring into a transport ladle
- Transfer of molten metal into a transport holding furnace
Typical industries
- Aluminium foundries
- Non-ferrous metal foundries
- Automotive industry
- Metal casting production
- Mechanical engineering
- Foundry production with regular aluminium melting
Main benefits
- Reduced gas consumption thanks to recuperation
- High melting output for regular foundry production
- Lower heat losses thanks to insulation and rotary lid
- Efficient melting of aluminium alloys
- Quick crucible replacement
Suitable for customers who need a recuperative gas-fired melting furnace for aluminium alloys with high melting output and reduced gas consumption.
If recuperation is not required, consider the PTP gas-fired melting furnace. For tilting discharge of molten metal, consider the PTSPR recuperative gas-fired tilting melting furnace.

Optional accessories available at additional cost
- Crucible
- Charging thermocouple with protective tube
- Thermocouple in the crucible wall (only furnaces for temperatures of 1,200 °C)
- Controller measuring loop calibration (thermocouple + controller)
- Connection between the furnace and switchboard within a metal hose with a metal sheath. Always necessary for lengths over 5 m
- System to check for cracks in the crucible
