16 -- FLASH EVAPORATOR SYSTEM POC A. Gawronski, Program Manager, TL-PCC J. Sue Goff, Contracting Officer. NASA KSC has a requirement for one (1) each High Load and Topping Evaporator for the Flash Evaporator System used on the Space Shuttle Orbiter. Hamilton Standard is the Original Equipment Manufacturer (OEM) for the High Load Evaporator (P/N SV764263-8) and the Topping Evaporator (P/N SV764263-9). The High Load and Topping Evaporators are the main elements of the Flash Evaporator System (FES). The function of the evaporators is to provide heat transfer from the two Orbiter Freon Coolant Loops to expendable water. Each evaporator consists of three basic parts made of aluminum alloy: a cylindrical evaporator core, and Anti-Carryover Device, and a valve/nozzle mounting plate. Evaporant water is sprayed on the core's grooved inner surface to cool dual Freon loops flowing in finned passages. Hamilton Standard maintains responsibility for Orbiter FES design and sustaining engineering. The company has its own data bases for FES information. The Evaporators will be utilized in FES repair efforts. Because Hamilton Standard has been involved with the Shuttle Program since its inception, they have gained the knowledge and established the interfaces necessary to perform production activities without compromising the integrity of the hardware. Hamilton Standard possesses the unique processes, the unique quality systems, unique laboratory equipment, metallurgy, and FES integration assessment capabilities required to build the FES Evaporators to meet NASA's requirements. Hamilton Standard is the only source certified by NASA for FES repair/manufacture, and the only known source for this type of hardware build or repair. Delivery of the High Load and Topping Evaporators is required by June 30, 1997. All responsible sources may submit a written response to the notice for consideration by the Agency. The response should include a description of the technical qualifications and experience of the responder. This is not a request for proposal. Responses should be addressed to NASA, John F. Kennedy Space Center, Attn: J. Sue Goff, Contracting Officer, Mail Code: OP-MSO-L, Kennedy Space Center, FL 32899. Responses must be received no later than 7 days from the date of publication of this notice. Telephonic responses shall not be honored. (0024)
