FPSC Cryocooler
Free Piston Stirling Cryocooler is a type of cooling system that doesn’t use a compressor. Instead, it cools by repeatedly compressing and expanding helium gas. Helium is a safe gas that doesn’t harm the environment. Arctic Active Cooling Cryocooler has been widely used in Bio-science, military, laboratory devices, analytical instruments and vaccines at low temperatures. The Sterling engine is a new technology for small and deep freezing, quickly reaching temperatures as low as -120℃ in just a few minutes.

Application
Application Examples
Free Piston Stirling Cryocoolers are complete CFC-free systems, using natural Helium gas. They are small, portable, and are widely used for precise temperature control for under -160℃ max. The default version of Stirling coolers includes pistons, heat exchangers, and compression spaces. But we see technological advancements in all industries, such as Biotech, Pharmaceutical, Food, Energy, Chemical, Medical, Bio-Science, logistics, and Metrology.
Working Process
Isovolumetric Exothermic Process
Both pistons move in the same direction at the same time and the volume of gas remains constant until the compression piston reaches its dead center. As the gas passes through the regenerator, the heat is transferred to the packing, the temperature is reduced, and the pressure is also reduced.Isothermal Compression
The compression piston moves while the expansion piston does not. Gas is isothermally compressed, compression heat is transferred through the cooler to the coolant (water or air), the temperature is maintained, pressure is increased, and volume is decreased.Isothermal Expansion Process
The compression piston stops at the stop point while the expansion piston continues to move to the stop point. The gas is isothermally expanded and absorbs a certain amount of heat (cooling capacity) from the low-temperature heat source (cooling object) through the cold heat exchanger. The volume increases and the pressure decreases.Constant Volume Heating Process
Both pistons move in the same direction at the same time to the stop point, the gas volume remains unchanged and returns to the starting position. As the gas passes through, it absorbs heat from the regenerator packing, and the temperature increases while the pressure increases.
