Ambient Vaporizer/Model A64SS-18. 6-UHP-EP-LNG/1/

NASA's Shared Services Center is procuring one Model A64SS-18.6-UHP-EP-LNG Ambient Vaporizer through a sole source solicitation. This specialized cryogenic equipment is designed to vaporize liquid methane at a flow rate of 56,663 standard cubic feet per hour while maintaining outlet gas temperatures within 20 degrees Fahrenheit of ambient conditions. The vaporizer must meet specific technical requirements including a maximum allowable working pressure of 15,000 psig, an operating pressure of 10,000 psig, 304 electro-polished stainless steel construction, and ASME flange connections. The government is accepting written capabilities and qualifications statements from interested organizations until 7 a.m. Central Standard Time on April 29, 2026, to determine whether the procurement should proceed on a competitive basis or as a sole source award; however, the final decision regarding competition remains at the government's discretion. Submissions must demonstrate the organization's ability to provide this equipment and should be directed to Shanna Patterson, Procurement Specialist, at Shanna.L.Patterson@nasa.gov.

This procurement carries no set-aside designation and is being pursued as a sole source requirement with Acme Cryogenics identified as the only supplier of this specific model within Stennis Space Center's contractual local territory. The government selected sole source procurement to ensure commonality with existing Acme Cryogenic vaporizers already in operation at the facility, thereby promoting operational efficiencies and minimizing compatibility and redesign risks. The equipment is approximately 75 inches wide by 75 inches deep by 250 inches tall, with a clean weight of 6,451 pounds and an iced weight of 37,669 pounds, requiring delivery within 36 weeks to John C. Stennis Space Center in Mississippi. The estimated lead-time for delivery is 10 weeks as soon as possible, though the total estimated contract value has been redacted from available documentation. This procurement falls under NAICS code 332999 (All Other Miscellaneous Fabricated Metal Product Manufacturing) and PSC code 6695 (Combination and Miscellaneous Instruments).
