About this file
This is a Statement of Work for the procurement of a cryocooler system to be delivered to NASA's Marshall Space Flight Center (MSFC). The contractor shall design, construct, ensure proper operation, and deliver a complete cryocooler system within 9 months of contract award. The system must include a compressor, cold head with integrated helium gas heat exchanger, control panel, flex lines connecting the compressor to the cold head, and all relevant documentation.
The cryocooler system must meet specific performance and technical requirements: achieve 100 watts or greater heat removal capacity at 20K temperature with a base temperature equal to or less than 17K; the cold head must feature ½" VCR fittings for helium loop connection and withstand a maximum allowable pressure of at least 300 psig; the system shall be mountable to a 16" OD ASA flange with 12" nozzle; operate on 480VAC, 3-phase, 60 Hz power; require water cooling at 5 gallons per minute or less at 80°F; and include flex lines between the compressor and cold head with a minimum length of 10 feet. Work shall be performed at the vendor's facility with delivery to MSFC.
