Description
Summary:The article introduces a low-temperature system operating on a mix of refrigerants R134a/R23, as well as its operating scheme, structural diagram, and appearance. The design proved operable, reliable, and efficient. The system needed three hours for the temperature to drop as low as -70°C. The operating temperatures and pressures endowed the system with a reliable, stable, and long-time performance. The device can be used for low-temperature processing and storage of biotechnological materials, as well as in pharmacy and environment testing.
