Portable Ultra-Low Temperature Medical Freezer

Product Overview

The portable ultra-low temperature medical freezer is a compact, high-performance cooling solution based on free-piston Stirling refrigeration technology. It combines powerful ultra-low temperature capability with excellent portability. Designed for the storage and transport of temperature-sensitive materials such as vaccines, biological products, and research samples, the freezer ensures cold-chain integrity and safety across laboratory, clinical, and field applications.

Operating Principle

The system uses free-piston Stirling cooling technology with high-purity helium as the refrigerant. Efficient reciprocating thermodynamic cycles generate stable ultra-low temperatures, while a high-performance thermal transfer fluid ensures effective heat removal. Integrated high-precision temperature sensors and an intelligent control system continuously monitor and regulate the internal temperature, maintaining minimal temperature fluctuation and reliable long-term stability.
