The National Institute of Standards and Technology (NIST) is seeking information from vendors capable of providing an oil-free helium recirculating compressor for use in a closed-cycle flow cryostat system. The compressor must meet specific technical requirements, including an output pressure exceeding 110 psig, a minimum flow rate of 25 standard liters per minute, and a leak rate no greater than 5 x 10^-5 mbar liters per second, while ensuring gas tightness and employing mechanical compression without oil. This procurement is crucial for advancing precision and reliability in cryogenic technology, and interested organizations should submit their capability statements to Angela Hitt at angela.hitt@nist.gov by 1 p.m. MST on October 23, 2024, as no proposals or quotes will be accepted at this time.
