Ultra low temperature freezing system

The ultra-low temperature freezer (-80 ℃ • -40 ℃) is a machine that can lower the vapor and liquid of objects to extremely low temperatures. Its working principle is mainly through compression refrigeration. It can adopt a cascade design at low temperatures of -50 ℃, and single machine two-stage compression refrigeration can be used above -40 ℃. The principle is to compress the refrigerant into a high-temperature and high-pressure gas, then cool it into a high-pressure liquid through a condenser, and then expand the high-pressure liquid into a low-temperature and low-pressure gas through an expansion valve to achieve the goal of reducing the temperature of the target object. This is similar to conventional principles, but our company is more prominent in the field of low temperature. Ultra low temperature refrigerators are widely used in the research and development of life sciences, chemistry, physics, and other fields. For example, in the field of biomedical research, ultra-low temperature refrigerators are used to preserve cells, freeze-drying, tissues, organs, and even the entire organism. Many breakthroughs in biomedical research cannot be achieved without the application of ultra-low temperature technology. In addition, ultra-low temperature refrigerators are also widely used in manufacturing processes in fields such as semiconductors and optoelectronics, such as ultra-high vacuum refrigeration and pulse valve refrigeration. The emergence of ultra-low temperature refrigerators has brought great convenience to people's scientific research and industrial development. However, 10 years ago, it was a relatively expensive equipment. After years of research and development by our senior engineers, manufacturing costs have been greatly reduced. However, users also need professional personnel to operate and maintain it.
