Phase II Demonstration of a Compact Cryocooler

Mainstream has developed an innovative cryocooler design utilizing a multi-cascaded single-compressor vapor-compression system. We have demonstrated the potential of this configuration, and have identified a specific Army application.The Phase II effort is significant, in that a full scale cryocooler for use by Army Forward Medical Applications (as a critical component of a unique high purity oxygen production and liquefaction system) will be designed and demonstrated in Phase II.Phase III Commercialization involves FDA approval of the device and full scale production by our commercial partner to satisfy current Army and Air Force Medical Command requirements. This effort will be performed in parallel with a cost-matched Fast-Trackprogram to develop the compact oxygen generation system with a demonstration of the completed system in 24 months.We have already demonstrated that this technology is superior to all current and proposed solutions to provide compact cryocooling, and the unique multi-level cooling of this configuration further minimizes the cooling load at the coldest temperature,further reducing the size of the system. Experiments have already demonstrated that this unique cryocooler is significantly more efficient than alternative configurations.
