Main products: compact, lightweight, long-life high-frequency pulse tube cryocoolers which can fully meet the customized cooling needs of infrared detectors

 

In the field of infrared detection, we developed the single and multi-stage compact, lightweight and long-life high-frequency pulse tube cryocoolers covering 2 K to ambient temperature, and the cooling performance reached the international advanced standards. The cooling power range of the cryocoolers is from milliwatts to hundreds of watts. The weight of the micro one is 500 g, while the weight of the medium-sized one is less than 10 kg. A single cryocooler can reach more than 50,000 hours of MTBF, and meet the customized cooling needs of infrared detectors with short, medium, long and very-long wavelengths.
