Inert gas blanketing (SPAL)


Our SPAL technology helps producers of steel products to melt cleaner metals to produce castings with fewer defects, enhanced mechanical properties and lower rejects.

The technology uses liquid cryogenics (argon or nitrogen), to reduce interactions between molten metal and atmospheric gases such as oxygen, nitrogen, water vapor, and carbon dioxide during air melting operations.
