Description

Presolicitation Notice - Synopsis

NASA Glenn Research Center/GRC has a requirement for the purchase of liquefiers/refrigerators to support space propulsion and cryogenic research and development activities.

The helium liquefier/refrigerator system must: Implement gas-bearing helium turbo-expanders that have a variable brake design and are located in the cold box at a temperature level below the liquid nitrogen assisted pre-cooling. Variable brake must allow for an output power reduction to approximately 30% of the maximum, while maintaining high efficiency. No more than three turbines are to be used. Be capable of a maximum (liquefaction) capacity of no less than 6.8 g/s of make-up gas supplied at ambient temperatures up to 305.4 K and 1.05 bara, that is supplied to a load at a pressure of 3.5 bara and is sub-cooled to a temperature within 0.05 K of the saturation temperature corresponding to 1.25 bara. For this operating point, the supply pressure to the cold box must not exceed 14 bara. Be capable of using liquid nitrogen to assist in the pre-cooling of the helium down to approximately 80 K. The liquid nitrogen assisted pre-cooling consumption must not exceed 3.7 g/s per 1 g/s of make-up (helium) gas. Be capable of operating, at a reduced capacity, without liquid nitrogen assisted pre-cooling, but using the cold box turbines without requiring the throttling of the (turbine) inlet valves. Not include an integrated purifier. Be designed to allow use of an alternate compressor capable of a discharge pressure of 18.25 bara., utilizing its supplied exergy (at that pressure level). Mechanical design must conform to ASME B31.3 and ASME BPVC Section VIII, as applicable. All vacuum vessels must be designed to ASME BPVC Section VIII, Division 1 or 2 (but are not required to have a U-stamp). The high pressure helium stream for cold box system must be rated no less than 18.25 bara per ASME B31.3. Lower pressure helium and nitrogen streams for cold box...
