S-RAM Dynamics has secured a small business independent research (SBIR) contract to produce a next-generation carbon dioxide (CO2) refrigeration system for the US Army.
Awarded by the US Army Natick Soldier Systems Center (NSSC), the $1m contract will require the company to build and test a mobile refrigeration system prototype using C02, a natural refrigerant.
S-RAM president Lee Jestings said: "We are pleased the army recognised the impact of our proprietary CO2 compressor and expander technology to reduce energy consumption while eliminating harmful greenhouse gas emissions.
"This demonstration contract will help accelerate our commercialisation efforts for a broad range of refrigeration and heat pump products."
Collaborating with Purdue University at the Ray W. Herrick laboratories, S-RAM will attempt to reduce the army’s energy consumption by 50% by minimising the use of fuel and synthetic refrigerants.
The company will develop a system that uses compressor technology, as well as an axial piston compressor with an opposed piston expander, to recapture energy and boost system performance.
Once developed, the new mobile refrigeration system is expected to be installed on the army’s multi-temperature refrigerated container system (MTRCS).
Work under the contract is expected to be performed in Tennessee, US.
