Cryogenic Dilution Refrigerator System Supply

A complete cryogen-free dilution refrigerator system is being procured to achieve temperatures below 10 millikelvin for advanced quantum materials research, integrating pulse tube precooling with helium-3 and helium-4 mixture cooling to eliminate reliance on liquid cryogens. The system must be fully self-contained, reliable, and optimized for continuous operation in a laboratory environment, ensuring thermal stability and minimal vibration to support sensitive quantum experiments. The contract is a subcontract under the Department of Energy, administered by Brookhaven National Laboratory, with a response deadline of June 1, 2026, and performance must occur at Upton, New York, 11973. The procurement falls under NAICS code 333318 for other industrial machinery manufacturing and requires the supplier to deliver a turnkey solution capable of sustained ultra-low temperature operation without conventional cryogens, demonstrating proven technical capability and engineering robustness for cutting-edge scientific applications.
