Advantage

Environmentally Friendly
Free Piston Stirling Cryocooler adopts helium, a naturally occurring gas that is harmless to the human body and environment

Super Cooling Capacity
The FPSC can easily reach temperatures below -99ºC (on the cold head). 

Lightweight & Compact Size
Weight: 6~7 kgs (half the weight of compressor systems) The FPSC is suitable for life science, laboratory, medical, food, small countertop freezers, portable refrigerators, and special low-temperature applications.

Precise Temp. Control
The FPSC is continuously modulated by electronic circuitry, not by on/off cycling as in compressor systems. The control circuits maintain a constant set temperature, allowing for temperature control, is ideal which is or sensitive applications.

Energy Savings
The RIGID FPSC consumes 40W~100W of power and is compatible with a variety of power sources such as 12V or 24V direct power, photovoltaic (solar cells), or in-house generators, as well as 110/220VAC power.
 

Application

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 -160ºC 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.

Stirling Cooler List

FAQ

1. What is a Stirling cooler?

A Stirling cooler is a refrigeration system that operates based on the Stirling cycle. It uses the temperature difference between an external heat source and a cooling source to induce compression and expansion in a gas (usually helium) to transfer heat and achieve cooling.

2. How does a Stirling cooler work?

A Stirling cooler works through a closed gas cycle (typically helium) where the gas changes temperature during the expansion and compression phases. During the expansion phase, the gas absorbs heat from a high-temperature zone and expands, lowering its temperature. In the compression phase, the gas is compressed, releasing heat. This heat exchange mechanism provides the cooling effect.

3. What are the advantages of a Stirling cooler?

• High efficiency: Stirling coolers are highly efficient for low-temperature cooling applications, especially at very low temperatures (e.g., below -100°C).
• No refrigerants: They use gas as the working medium, avoiding the issues associated with refrigerants in traditional compressor-based systems.
• Low noise and vibration: Compared to traditional compressor-based cooling systems, Stirling coolers generally operate with less noise and vibration.
• Precise temperature control: They offer precise temperature control, making them suitable for sensitive applications that require stable temperatures.

4. What are the disadvantages of a Stirling cooler?

• Low power output: Stirling coolers are suited for small-scale cooling applications, and may not perform as well in high-power-demand environments compared to traditional compressor systems.
• High cost: Due to the complex working principle and precise construction, Stirling coolers are generally more expensive to manufacture.

5. What are the applications of a Stirling cooler?

Stirling coolers are widely used in the following fields:

• Cryogenic cooling: For laboratory experiments, medical devices, and refrigeration equipment.
• Aerospace: Used for cooling in satellites and deep space probes.
• Environmental testing: Simulating low-temperature environments for equipment testing.
• Portable cooling systems: Used in portable devices that require cooling.

6. What is the efficiency of a Stirling cooler?

The efficiency of a Stirling cooler is closely tied to its operating temperature difference and system design. At lower temperatures, Stirling coolers can achieve high COP (Coefficient of Performance), but the efficiency may decrease when working with higher temperature differences.

7. What are the maintenance requirements for a Stirling cooler?

Stirling coolers generally require less maintenance since they do not have moving parts like traditional compressors. Main maintenance tasks might include:

• Ensuring the working medium (e.g., helium) maintains proper pressure and purity.
• Periodically checking for leaks and the operational status of the cooler.
• Cleaning air filters and heat exchange surfaces to maintain optimal heat transfer.

8. What is the lifespan of a Stirling cooler?

Stirling coolers generally have a long lifespan, often reaching tens of thousands of operating hours, especially with proper maintenance and good operating conditions.

9. How does a Stirling cooler differ from a traditional compressor-based cooler?

• Working principle: A Stirling cooler operates based on the Stirling cycle, while a traditional compressor cooler uses a compressor to compress a refrigerant, which is then expanded in a condenser.
• Efficiency: Stirling coolers perform better at lower temperatures, while compressor-based coolers tend to be more efficient at higher temperature differences.
• Size and weight: Stirling coolers are typically larger and heavier compared to compressor-based coolers, making them better suited for low-power, small-scale applications.

10. What applications are suitable for a Stirling cooler?

Stirling coolers are ideal for:

• High-efficiency cryogenic cooling, such as for superconductors.
• Medical devices that require high reliability and low noise.
• Laboratories or research environments that need precise temperature control.

11. How do you select the right Stirling cooler?

When choosing a Stirling cooler, consider the following factors:

• Cooling requirements: Determine the required cooling capacity and temperature range.
• Size constraints: Consider the space limitations of your system.
• Cost and budget: Stirling coolers tend to be more expensive, so selecting the right model within your budget is important.
• Operating environment: Select a system suited for the specific conditions of your application, such as low-temperature environments or sensitivity to vibrations.
