NASA's National Aeronautics and Space Administration (NASA) is seeking to procure a new chiller for its Rotorcraft Hover Facility at the Langley Research Center. The project involves replacing a failed water chiller that is critical for cooling water-cooled motors used in rotorcraft wind tunnel models, necessitating the installation of a new 5-ton chiller that meets specific technical requirements, including a flow rate exceeding 15 GPM and compatibility with a 208V – 3-phase – 60 Hz electrical system. This procurement is vital for maintaining the operational efficiency of the Rotorcraft Hover Test Facility, reflecting NASA's commitment to upgrading its research capabilities. Interested organizations must submit their capabilities and qualifications in writing to Kacey Hickman at kacey.l.hickman@nasa.gov by 3:00 p.m. Central Standard Time on February 4, 2025, to be considered for this sole source contract.
