E-MAIL: Timothy C. Pierce, Timothy.C.Pierce@lerc.nasa.gov. NASA/LeRC plans to issue a Request for Offer (RFO) for the fabrication of one (1) Liquid Oxygen (LOX) Heat Exchanger System and one (1) Liquid Hydrogen (LH2) Heat Exchanger System to be used in NASA's X-33 Densification Experiment. The LOX heat exchanger system shall provide subcooled LOX at specified tube side outlet conditions. The shellside of the LOX heat exchanger system will operate with a subcooled LN2 boiling bath. The bath will be maintained at a low subatmospheric pressure to provide a colder thermal heat sink for the LOX flowing through the tubes. The LH2 heat exchanger system shall provide subcooled LH2 at specified tube side outlet conditions. The shellside of the LH2 heat exchanger system will operate with a subcooled LH2 boiling bath. The bath will be maintained at a low subatmospheric pressure to provide a colder thermal heat sink for the LH2 flowing through the tubes. Documentation and Installation Support shall be required for both systems. The Government does not intend to acquire a commercial item using FAR Part 12. See Note 26. The SIC Code and Size Standard are 3561 and 500 employees, respectively. The DPAS Rating for this procurement is DO-C9.
