Mu2e Ambient Vaporizers

The Department of Energy Fermi National Accelerator Laboratory is soliciting proposals for two ambient vaporizers (liquid nitrogen heat exchangers) for the Mu2e experiment through RFP 369431swk. The procurement requires firm-fixed price proposals for two identical heat exchangers designed to operate in a parallel switching configuration, with each unit capable of handling full system flow across all operating modes including continuous 24/7/365 operation and potential high-flow conditions for one hour per month. The vaporizers must meet stringent technical specifications including a design pressure of 150 psig, operating temperatures from -320°F to 120°F, and the ability to withstand outdoor environmental conditions including temperatures from -30°F to 120°F and 100 mph winds. The procurement will utilize a best value source selection process, with award made to the lowest-priced technically acceptable offeror. Proposals are due by 5:00 PM Central Time on June 25, 2025, and proposals exceeding $10,000 must include completed SARC and PUR-466 certification documents.

This procurement does not utilize any set-aside designations and no incumbent contractors are identified in the solicitation materials. While specific award values are not disclosed, the requirement for additional certification documentation suggests the contract value may exceed $10,000, with enhanced requirements at thresholds of $150,000 and $500,000. The contract calls for delivery of two complete ambient vaporizer units that must be shipped F.O.B. to the Fermilab Receiving Warehouse 2 facility. Performance will take place in Batavia, Illinois, where the heat exchangers will be installed outdoors at the Fermi National Accelerator Laboratory as part of the Mu2e experimental apparatus. The procurement falls under NAICS code 334516 (Analytical Laboratory Instrument Manufacturing) and PSC code 6640 (Laboratory Equipment and Supplies), reflecting the specialized scientific nature of the equipment being procured.
