DigInfo - http://movie.diginfo.tv The environmentally-friendly, next-generation Stirling Cooling System, exhibited by Twinbird Corporation, uses a natural refrigeration agent and can be used in a variety of fields. This FPSC (Free Piston Stirling Cooler) is hermetically sealed in a stainless steel casing. Helium gas is repeatedly compressed and adiabatically expanded as two pistons reciprocate 80 times per second in one cylinder As this occurs, the tip (heat absorbing area) is cooled. When a heat exchanger is installed on this heat absorbing area, the item targeted for cooling can be cooled, and the temperature of the heat absorbing area can be lowered from minus 50°C to minus 120°C in just a few minutes. A lineup of Stirling Cooler FPSC products that includes 40W, 50W, 80W, and 150W models is available to meet a variety of application needs.
