GU-500 Indutherm

These machines are developed especially for granulating of metal bullions into proper grains. They are used with a separate removable
granulation tank (no tank integrated) and are available with crucible sizes from 170 ccm up to 12000 ccm.

The major applications are

• Preparation of alloys out of gold and master alloy…
• Preparation of alloy components…
• Preparation of alloys from components…
• Cleaning up of already casted metal…

…under inert gas atmosphere or under vacuum

Major applications at customer:

• Granulating of metal bullions into proper grains
• Preparation of alloys out of gold and master alloy under protecting gas atmosphere or under vacuum
• Cleaning up of already cast metal under protecting gas atmosphere or under vacuum

Major advantages:

• Excellent mixing of molten metal due to low frequency generator
• Melting under protection gas atmosphere or vacuum
• Alloy mixing because of sealing rod system
• Automatic protective gas control
• Turbo – pressure device for cleaning the complete crucible
• 16 temperature programs
• Stainless steel granulation tank with pneumatic lift
• Easy emptying of the granulating tank
