  • RIGID Stirling Compact Mobile Freezer adopts Japanese Stirling refrigeration technology, using environmentally safe helium as the refrigerant, with high life, high safety, and high-reliability performance.


    Because of the unique Stirling technology, this freezer is not afraid of vibration and transportation bumps. At the same time, it can be equipped with multiple Stirling coolers. During pre-cooling, multiple Stirling coolers can be started at the same time to achieve shorter pre-cooling time, and during normal operation, it can be put into a multi-prepared mode.


    Furthermore, the Stirling Compact Mobile Freezer with modular cold chain collector. It's a standard, distributable device that is not only a cold chain transport device, but also your "mobile cold storage". At the same time, the IoT background can support the positioning of refrigerators, real-time view of operational data, support remote control of the machine, and can export the data so that the whole process can be controlled and traced.
