Helium Recovery Unit Meets Green Requirements

Pfeiffer Vacuum’s HRU Helium Recovery Unit reclaims used helium when testing parts for leak tightness. Helium test gas is an essential part of customized leak detection systems. It is a non-renewable, limited supply commodity with costs increasing yearly because of growing demand for higher quality manufactured parts in many industries. In an effort to be as efficient and resource-conserving as possible, these helium recovery units recover the helium gas used in leak detection and allow it to be recycled. The recovery of used helium is particularly useful for meeting the environmental certification requirements under DIN EN ISO 14001, and for saving resources. The helium recovery units are designed as standalone systems and can recover helium test gas regardless of the leak detection system manufacturer. Depending on the process parameters, up to 98% of the inert gas can be recovered with helium concentrations between 10 and 95%. Two helium recovery systems are available: the balloon recovery and the tank recovery.
