Products Description

 

Stirling Portable Freezer utilizes Stirling cryogenic cooling technology. Featuring a unique lightweight portable design, the unit has a small footprint, light weight, powerful cooling performance, and a wide cryogenic temperature range. This product is primarily used in laboratories for cryogenic storage and transport, industrial extreme environment simulation testing, cold chain transport in the pharmaceutical industry, storage and transport of biological samples, low-temperature life science cold chains, clinical medicine, outdoor camping, and home ULT storage, among other fields. It enables safe storage and distribution of biologics and vaccines, facilitates long-term preservation of biological samples, and boasts low power consumption—capable of operating with various power sources such as batteries, 12V vehicle power, or solar panels. For temperature-sensitive samples and specimens used in remote clinical trials or field applications, pharmaceutical IoT monitoring devices can be selected to achieve real-time temperature recording and monitoring.
Advantages: 1.Utilizing patented Stirling cryogenic technology, it delivers superior performance with powerful cooling, rapid cool down, low temperature, high efficiency, and low energy consumption.
2.With a broad temperature range adjustable from 18°C to -86°C, it simultaneously meets both refrigeration and freezing needs—one unit for multiple uses.
3.Precise temperature control maintains fluctuations within ±1°C, ensuring that stored biological samples such as vaccines, cells,
proteins, and nucleic acids remain protected from inactivation, denaturation, or degradation due to temperature variations.
4.The high-efficiency Stirling variable-frequency cooling system saves up to 75% more energy compared to similar refrigerators.
5.With a compact volume of only 0.1 m³, the Stirling refrigerator can be placed virtually anywhere.
6.Weighing just 38 lbs and designed with ergonomics in mind, it is easy to carry and transport.
7.It uses 100% environmentally friendly refrigerant, making it a green and sustainable solution.
8.It is compatible with various power sources, including batteries, 12V vehicle power, and solar panels.
9.The 304 stainless steel interior lining ensures reliable durability and safe storage for both food and samples.

Productive Process
Free Piston Stirling Cooler
Stirling refrigerator does work by the thermal expansion and contraction of gases as they change between hot and cold environments. Compared with traditional refrigeration technology, the advantages of free piston Stirling technology are High efficiency , low noise , low vibration , Oil-free operation , long life and 100% natural refrigerants to support sustainable environmentally-friendly operations. And also Stirling Refrigerator can ignore operating angle , 360° operating is OK. It can precise control refrigerating capacity out freely.
