Quantum Design (QD) (CSA CSM) and Sumitomo (SHI) Cryogenics of America, Inc., (CSA CSM) announced a new variable speed helium compressor developed for use with cryogen-free instrumentation.
The new R-98 double inverter-driven helium compressor, the first in SHI’s new Revolution™ Series, is compatible with a range of SHI’s Gifford-McMahon and Pulse Tube two-stage cryocoolers. The new compressor represents the latest in “energy smart” helium compressors that reduce the operating costs of cryogenically cooled instrumentation. Variable speed operation is not only energy efficient, but also reduces servicing requirements of traditional single-speed compressors.
In addition, low speed operation translates into lower vibrations at the cold head, which enables sensitive measuring instrumentation to operate in a low noise environment, while high speed operation allows for faster cooldown time of the cold head. The R-98 features remote control operation, extensive real time diagnostics, a patented modular cooling architecture and a full computer control interface. It is compact and quiet, making it ideal for operation in laboratories and workspaces.
Dr. Stefano Spagna, CTO of Quantum Design, commented, “QD and SHI have had a close relationship since the early 1990s, when together we introduced the EverCool helium recondensing technology for our popular PPMS and MPMS platforms. It is now great to see our innovative companies, each with long histories in cryogenics, coming together once again to collaborate on the next generation of cooling technologies.”
David Dedman, CEO of SHI, added, “The SHI Cryogenics Group has a long history of advancing cryogenic technology through strategic partnerships and internal research and development. We are excited to introduce the R-98 compressor as the result of our latest collaboration with Quantum Design. The new ‘Revolution’ Series expands SHI’s already extensive lineup and leverages QD’s and SHI’s strengths as technology leaders in the cryogenic community.”
