Core Technology

We are a leading Stirling cryocooler manufacturer in China. We can develop professional Stirling cooling solutions tailored to customer requirements.
Works in Any Orientation:Adopting internationally advanced free-piston Stirling technology with no liquid lubrication components, it can be used upside down without concern, enabling flexible and unrestricted product design.  Compact & Lightweigh:tWith dimensions of only 170 × 144 × 286.5 mm, its structure is over 40% simpler than that of a conventional compressor, making it highly suitable for transportation. Weighing just 3.25 kg, it reduces the load for your application development and facilitates the integration of other critical components.  Temperature Control Performance:The cold head temperature ranges from -150°C to +20°C, supporting precise temperature control with a temperature difference of ±0.1°C.  Safe & Eco-Friendly:Uses helium as the refrigerant, contributing to the protection of the environment.
Operable in Any Orientation:No restrictions on installation position, enabling a wider range of user scenarios. It operates stably even under bumpy, shocking and unsteady conditions.  Extra-Long Service Life:The air-floating structure forms an air film between the piston and cylinder, reducing wear and greatly improving overall stability. The service life can reach 160,000 hours.  Precise Temperature Control:The cold head temperature ranges from -150°C to +20°C, with precise temperature control accuracy of ±0.1°C.  Safe & Eco-Friendly:Uses helium as the refrigerant, contributing to environmental protection.
Professional Positioning:Designed for precision ultra-low temperature fields including scientific research, medical treatment and aerospace, this high-performance Stirling cryocooler delivers stable ultra-low temperature retention and rapid cooling.  Outstanding Core Performance:With a 1200W free-piston structure, it provides 300W cooling capacity at -110℃, reaches -150℃ in 30 minutes, and features ±0.1℃ temperature accuracy and noise ≤45dB. Its efficiency is over twice that of traditional devices, cutting energy consumption by more than 50%.  Long Service Life & High Stability:The machine offers a designed service life of over 70,000 hours, ensuring stable and reliable operation in long-term continuous working conditions.  Wide Range of Applications:Suitable for aerospace detector cooling, MRI superconducting magnet cooling, biological sample cryogenic storage, natural gas liquefaction, waste heat recovery and power generation.  Compact & Cost-Effective Design:Modular compact structure enables easy integration, vibration reduction and noise reduction. It features low noise, low maintenance, strong environmental adaptability and optimized full life-cycle cost.
