Mobile Military CO2 Refrigeration

S-RAM Dynamics (S-RAM) will design, fabricate, test and commercialize a transcritical CO2 refrigeration system using the recently invented S-RAM CO2 oil-less, integrated expander/compressor unit (ECU). This CO2 refrigeration system will be targeted for mobile military cold storage assets and commercial transportation refrigeration units. The refrigeration system will meet the specified space requirements and will exceed the Army coefficient of performance (COP) target. The CO2 refrigeration units will be commercialized within four years and will be manufactured in the United States. S-RAM Dynamics (S-RAM) is particularly qualified for this Phase 1 project, and the timing of this solicitation is perfect. Today, as we write this proposal, the first generation S-RAM oil-less, variable displacement CO2 compressor is being tested on a custom-built CO2 test stand at the Herrick Laboratories at Purdue University. The first compressor efficiency tests have been excellent, exceeding the performance of currently available transcritical CO2 compressors.
