About
Free Piston Stirling Cooler (FPSC)
RIGID offers the Free Piston Stirling Cooler (FPSC), a cutting-edge solution for precise temperature control in industries that need ultra-low temperatures (down to -86°C), including biotech, food, energy, pharmaceuticals, medical, chemicals, logistics, metrology, and biosciences.
Unlike traditional compressors, the FPSC works by repeatedly compressing and expanding gas, using helium as a refrigerant. Helium is a safe, eco-friendly gas that poses no harm to the environment. FPSCs are commonly used in refrigerators, laboratory equipment, and vaccine storage, where low temperatures are crucial for transporting and storing goods. The system is compact and lightweight, weighing only 2.2 kg (4.85 lbs), making it easy to install and move.
The FPSC is a more efficient cooling solution than traditional compressors, with lower energy consumption. Thanks to its innovative MagLev technology, it is capable of deep freezing and offers precise temperature control down to -160°C.
If you need a reliable and efficient cooling system, the Free Piston Stirling Cryocooler is the solution you’ve been looking for!

How Stirling Cryocooler Works
The FPSC operates through a series of stages to achieve ultra-low temperatures:
The Free Piston Stirling Cryocooler works through carefully controlled processes to achieve efficient cooling. Here’s a simple breakdown of each step involved:
- Isovolumetric Exothermic Process
In this step, both pistons move in the same direction simultaneously. During this process, the gas’s volume stays the same. As the gas moves through the regenerator, heat is transferred to the packing material inside, which causes the gas to cool down. As the gas cools, its pressure also drops. This stage helps prepare the gas for the next cooling steps.
- Isothermal Compression
In this stage, the compression piston moves, but the expansion piston remains stationary. As the compression piston pushes, the gas is compressed while maintaining the same temperature (this is called “isothermal” compression). The heat generated from the compression is transferred out through the cooler, either into water or air, which keeps the temperature constant. As the gas is compressed, its pressure increases and its volume decreases.
- Isothermal Expansion Process
Now, the compression piston stops, and the expansion piston starts moving. In this step, the gas expands while staying at a constant temperature. The expansion allows the gas to absorb heat from the cooling object (such as a sample or equipment) through the cold heat exchanger. As the gas absorbs heat, its pressure decreases and its volume increases, which helps lower the temperature of the object being cooled.
- Constant Volume Heating Process
In the final step, both pistons move together in the same direction, pushing the gas back to its starting position. During this phase, the gas volume doesn’t change (it remains constant). As the gas passes through the regenerator again, it absorbs heat, causing both the temperature and pressure to increase. This process prepares the gas for the next cycle, where the cooling steps will repeat.
Each of these steps in the Stirling cycle is essential for achieving efficient cooling. By continuously repeating this process, the system can achieve very low temperatures with high precision, making it ideal for applications like vaccine storage or scientific research where temperature control is critical.

What they say about us.
FAQs
RIGID Stirling Coolers not only are the most environmentally sustainable ultra-low temperature coolers on the market, but they are also the most cost-effective with the lowest life cycle costs.
What's Free Piston Stirling Cooler (FPSC)?
The Free Piston Stirling Cooler (FPSC) is an elegant, completely sealed heat transfer system that has only two moving parts (a piston and a displacer), and which can use helium as the working fluid without concern about seal leakage.
How does a Stirling Cooler work?
The FPSC uses a heat exchanger to cool the cylinder down. The heat exchange involves repeating compression cycles.
The main body also contains a piston that moves up and down continuously. The material of choice for these pistons is usually stainless steel. The moving of the piston combined with the compression leads to a gas explosion.
What's Stirling engine used for?
Stirling engines are energy conversion devices that may be used as prime movers, refrigerating engines, or heat pumps. Currently, they are used commercially as cryogenic cooling systems and are under development as low-noise, low-emission automotive engines.
What's the temperature can RIGID Stirling Cooler achieve?
- RS40:-100°C
- RS80:-120°C
- RS100:-150°C
- RS100 plus:-160°C
What's Stirling Cooler input power?
- RS40:12V DC
- RS80:24V DC
- RS100:24~30V DC
- RS100 plus:24~30V DC
What's Power Liquid Chiller Warranty?
What refrigerant does a Stirling Cooler use?
How do I control a Stirling Cooler?
It has two control boards: the main drive board and the temperature control board. You just need to turn it on and set the temperature.
What is the lifespan of a Stirling Cooler?
The FPSC Stirling Cooler 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.
What do I need besides the Stirling Cooler?
This depends on your applications. Most clients will need to cool their heat exchangers like Aluminum plates or Cold adapters. Both of these are available as permanent or removable options. Some clients will design their own evaporator or air fin to transfer cold. RIGID engineers can help you to find the best solution.
Most customers will also require a vacuum flange to attach the Stirling Cryocooler to their Dewar or cryostat. For more information, feel free to contact Ann Wee | ann@rigidhvac.com
Do Stirling coolers need regular maintenance?
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.
Can I use the system in a vacuum?
Only RS100 Plus.
Does Stirling Cooler have installation orientation requirements?
No, they can be mounted in any orientation.
Besides, RIGID Stirling Cryocoolers offers several options for mounting. There are threaded hole patterns in the body of the cooler that is intended for mounting integration. The cooler can be mounted to the system via the cryostat flange either vertically or horizontally with the cryocooler cantilevered from the flange. Note: Care must be taken to not secure the cryocooler to the system structure in such a way that will induce stress in the body of the cryocooler.
Can I get a custom evaporator?
Yes, RIGID offers clients cold tips or heat exchangers, like Alumimum cold plates, and cold fin. So that they can easily modify the cold tip (or acceptor) configuration. A custom cold tip will NOT increase the cryocooler lead time. We will deliver it along with the Stirling cooler.
