Mainstream Engineering Corporation is focused on advanced thermal control and energy conversion technology, specifically thermal control systems, energy conversion devices, heat transfer, fluid flow, thermodynamics and nano-technology. In the past two decades there have been drastic increases in the power density and complexity of electronic and optical systems. These increases result in higher demand and more advanced thermal management strategies. Additionally, worldwide energy consumption associated with space cooling has increased substantially, thereby demanding more efficient space cooling technologies. Space cooling and refrigeration are responsible for a large portion of the fuel consumption among deployed troops. The company offers high-efficiency improved environmental control units (IECU) for rigid-walled shelter cooling, ducted modular environmental control units (MECUs) for tent cooling, and containerized RU for food, ice, and reserve blood supply storage. These units are ruggedized for the military environment and are refined constantly for enhanced efficiency and reliability. Another one of the company's products is purpose-built thermal management systems (TMSs) for atypical applications. The company has developed TMSs for cooling of communication equipment on Venus, cooling of high-energy laser weapon systems, cooling of wide bandwidth radar jamming electronics, and other applications where thermal management is critical to functionality. As the power density of central processing units, radar electronics, laser diodes, and other high power electronic components increases, so do the cooling demands. The firm has developed novel technologies for cooling high heat flux components to enhance local heat transfer coefficients. Mainstream is currently providing solutions to NASA, DOD, DOE, DOT, DOC, and USDA.
