Liquid Nitrogen Dewar

Fermi National Accelerator Laboratory, operating under the Department of Energy, is procuring one liquid nitrogen dewar with a minimum storage capacity of 15,000 gallons for the Mu2e project. The dewar must be vertically oriented and designed to ASME Boiler and Pressure Vessel Code standards, with specific technical requirements including a maximum allowable working pressure of 250 psig, design temperature of -321 degrees Fahrenheit, and normal operating pressure of 90 psig. The system must include two aluminum ambient air vaporizers capable of delivering 1,300 SCFH of nitrogen, comprehensive safety features, and maintain a boil-off rate of less than 0.2% per day. The solicitation will use a best value source selection process, with award going to the most responsible supplier whose proposal conforms to requirements and represents the lowest price among technically acceptable offerors. Proposals are due by 5 PM Central on September 8, 2025, and all proposals exceeding $10,000 must include completed PUR-466 and SARC forms.

This procurement does not utilize any set-aside designation and no incumbent contractors are identified in the solicitation documents. While specific budget ranges are not disclosed, the requirement for PUR-466 forms indicates the contract value exceeds $10,000, and the solicitation seeks a firm-fixed price proposal structure. The contract requires delivery of exactly one liquid nitrogen dewar unit with comprehensive technical specifications, documentation, testing protocols, and a minimum 12-month warranty. Performance will take place at Fermilab's facility in Batavia, Illinois, with delivery required to Fermilab Receiving Warehouse 2. The dewar must be capable of operating in external environments ranging from -13°F to +100°F and comes with extensive fabrication, quality assurance, and documentation requirements as outlined in Engineering Design Specification ED0013961.
