NASA's Shared Services Center awarded a purchase order to Stirling Cryogenics Inc. for $29,080 on November 24, 2025, to procure a cryofan for thermal interface development, with completion by May 23, 2026. The award is firm fixed price under FAR 13.106-1(b)(1)(i) sole source authority. Performance takes place in Lehighton, Pennsylvania. The cryofan must operate at maximum static system pressure of 450 psia across temperature ranges of 10–350 K, generating 200 meters of delta pressure at 20 cubic meters per hour with variable fan speeds between 9,000 and 18,000 rpm to support thermal control systems testing at Marshall Space Flight Center.
