Challenge
Argon is used as a shielding gas in the production of silicon for solar cells. After the process, the noble gas is often vented, even though it is costly and could be reused.

Solution
Through gas recycling, argon can be recovered and reused in the process. Piston compressors handle the compression and ensure the safe return of the gas.

The oil-free design ensures that gas purity is maintained and no additional treatment steps are required.

Implementation in Germany
In a gas recycling plant, argon is captured, compressed and reintegrated into the production process. The piston compressor used enables reliable gas recirculation under constant operating conditions.

The plant is designed for continuous operation and supports the efficient use of the noble gas employed.

Results

• Recovery and reuse of argon
• Maintenance of gas purity through oil-free compression
• Reduced operating costs due to lower gas consumption
• Stable and efficient plant operation
