Low Maintenance and Low Cost Cryocooler Navy SBIR FY2009.1 Sol No.: Navy SBIR FY2009.1 Topic No.: N091-051 Topic Title: Low Maintenance and Low Cost Cryocooler Proposal No.: N091-051-0567 Firm: Cryomech, Inc 113 Falso Drive Syracuse, New York 13211-2106 Contact: Peter Gifford Phone: (315) 455-2555 Web Site: www.cryomech.com Abstract: For onboard naval applications, a high cooling capacity, low cost, higher meantime between maintenance Gifford McMahon Cryorefrigerator is necessary. Cryomech manufacturers an existing cryocooler, the AL300, with sufficient cooling capacity; but, its standard MTBM is 10,000 hours and it has not been designed to meet onboard requirements. A redesign of the G-M Cold Head seals and displacer for 20,000 hours will be studied. Because the compressor package is most affected by the "onboard specification", a redesign of the affected components will also be studied. Benefits: All the developments under this project will be added to our standard products. These developments will increase the mean time between maintenance of all Cryomech G-M series cryocoolers.
