Inert gas blanketing

We supply industrial gases for clean melting processes and casting applications. Air Liquide’s SPAL technology uses liquid cryogenics, i.e. argon or nitrogen, to reduce interactions between molten metal and atmospheric gases such as oxygen, nitrogen and water vapor during air melting operations. This SPAL technology allows non-ferrous manufacturers to producing castings with fewer defects, enhanced mechanical properties and lower rejects.
