This is a Sources Sought/Request for Information (RFI) notice issued by the United States Marine Corps (USMC), Marine Corps Systems Command (MCSC), Program Manager Combat Support Systems (PM CSS), Product Manager Maintenance Support Systems (PdM MSS). PM CSS is conducting market research to identify potential sources for portable nitrogen generators capable of rapid deployment and operation in austere environments, including desert, mountainous, jungle, and shipboard locations. These generators must be capable of operating reliably within a temperature range of 0°F to above 100°F and humidity levels ranging from 70% to 80%. The USMC seeks two nitrogen generator systems: One high-pressure and one low-pressure with a desired to have an input power selection between a 110v/50-60Hz/1ph 20A connection in compliance with NEMA WD6 5-20P and a NATO SLAVE 28V DC connection in compliance with STANAG 4074. Also, desire to be transported in a transit case with wheels and have a weight allowable for four-man lift per MIL-STD-1472. The USMC additionally seeks information on vendors capable of providing any of the following capabilities: lifecycle maintenance, repair, sustainment, technical training, and warranty/technical support for portable nitrogen generators (both high and low pressure). The answers provided in response to this Request for Information (RFI) could aid the government in determining its acquisition strategy. Responders are encouraged to share information about potential solutions, even if the solution does not fully meet the characteristics below. **High-Pressure Nitrogen Generator Request for Information** The high-pressure portable nitrogen generator is expected to produce Class 2 and Class 1 purity, including grade A and grade B per Commercial Item Description A-A-59503D. It can be located at the following link by searching for Document ID A-A-59503D. https://quicksearch.dla.mil/qsSearch.aspx It is desired to produce pressures up to 3600 psi at the associated standard temperatures. It is desired to have a fill rate of no greater than 6 hours for a K-type bottle filled with Type 1, Grade A, Class 1 Nitrogen to 2400 psi. **Low-Pressure Nitrogen Generator Request for Information** The low-pressure portable nitrogen generator is desired to produce Class 2 purity, including grade A and grade B per Commercial Item Description A-A-59503D. It is desired to produce pressures up to 600 psi at the associated standard temperatures. Specify the fill rate on your response. The entity may be able to provide the capabilities listed above and integrate the portable nitrogen generator with the hardware and accessories required for the Marine Corps. Both High-Pressure and Low-Pressure Systems Both systems need to meet Class II requirements of MIL-PRF-28800 for operation and transportation in the field environment and requires an Item Unique Identification (IUID) marking per MIL-STD-130. Both systems should be able to be transported in a Joint…
