Helium Recovery: Design Considerations for Cold Spray Systems

Experience with Cold Spray process requirements and equipment selection can impact process gas economics for Cold Spray systems. Cold Spray processes with helium, as the process gas, require helium recovery for optimized economics. In most cases, acceptable process economics require a helium recovery system to achieve greater than 95% overall recovery. Design of a helium recovery system with substantial overall helium recovery demands an understanding of the entire Cold Spray process and specifics about the product to be manufactured.
