RIGID: Your First Choice for Free Piston Stirling Cooler Supplier
RIGID, one of the leading Chinese companies in terms of innovation, designed a free piston Stirling cooler – FPSC. The cooler takes the entire product to a whole new level where it can save a lot of energy and significantly improve efficiency.
The Stirling Cooler uses Helium as a gas, which differs from a compressor, is a cooling system that continuously repeats gas compression and adiabatic expansion and uses naturally helium gas as the refrigerant. Helium is a very safe gas. It is entirely harmless to our environment.
Free Piston Stirling Coolers use a Stirling engine, which has only two parts that move. The unit has a casing made of stainless steel, and all sensitive components are hermetically sealed inside. That is, they cost less in maintenance.

- Application Examples
Free Piston Stirling Coolers 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.
Feature (3)
-
RIGID Free Piston Stirling Cooler includes two pistons (pistons and balancing float) in the top compression chamber. The piston is driven by a linear motor, which sends helium gas to the balancing float (80 Hz).
-
Free Piston Stirling Cooler comes with a main drive board and display controller. Supports wide range control and accuracy to ±1°C. RIGID Stirling cooler, drive board, temperature control, and fan are integrated into one unit.
-
No Oil, No CFC. MagLev technology. It is a new type of completely CFC-free, high-efficiency, energy-saving, and environmental-protection Cooler, which uses a small amount of helium as the coolant.

Free Piston Stirling Cooler Projects
Stirling technology uses environmentally safe helium as its coolant. It has a linear motor and thermosiphon system that minimizes moving parts and maximizes reliability and working life.
The Stirling cycle is a closed thermodynamic cycle invented in 1816 by a Scottish minister, Robert Stirling.
A Stirling cryocooler utilizes the Stirling cycle to convert electricity into the movement of heat from the cold tip towards the heat rejecter.
Stirling engines are energy conversion devices used as prime movers, refrigerating, or heat pumps. Currently, they are used commercially as cryogenic cooling systems, deep and fast freezing, and cold chain logistics, and are under development as low-noise, low-emission automotive engines.
Temperature down to -90℃ in a few mins. And with our largest model RS100, the maximum temperature can reach to minus -150℃.
Although air is the traditional working fluid for Stirling engines, Hydrogen and Helium are also employed for improved performance due to their better thermal properties.
The Cryocooler design life is 5 years, and this is the recommended lifetime, although the current mean time to failure (MTTF) is over 200,000 hours, roughly 23 years.
The cryocooler components are enclosed in a welded pressure vessel and there is no way to access them. There is no maintenance required on the cryocooler. We do recommend keeping the air fins free of debris on units that have cooling fins.
