Since its establishment in 2010, Dandong Tongda Science & Technology Co., Ltd. has been focusing on the research, development, and production of X-ray analytical instruments and non-destructive testing equipment.The company has accumulated extensive experience in X-ray technology. In 2013, it became the undertaking unit of the "National Major Scientific Instrument and Equipment Development Project" for the X-ray single crystal diffractometer, supported by the Ministry of Science and Technology of China.
The Cryostream low-temperature liquid nitrogen cooling system, launched by Dandong Tongda Science & Technology, is a representative product of its Medium-low temperature accessory.This system is specifically designed for scientific experiments requiring precise low-temperature environments and integrates multiple advanced technologies.
Precise temperature control is the core advantage of the system. The Medium-low temperature accessory can maintain a temperature stability of up to 0.3 K within the standard temperature range of 100–300 K.Such high temperature stability provides a reliable environment for scientific experiments, ensuring the accuracy and reproducibility of experimental data.
Efficient cooling performance is another highlight. The system requires only 35 minutes to cool from room temperature to 100 K.The rapid cooling speed significantly enhances the work efficiency of researchers, making it particularly suitable for experimental scenarios requiring frequent temperature changes.
The intelligent control system makes operation more straightforward. Utilizing a fuzzy PID temperature control algorithm, the system achieves accurate and stable real-time control of low-temperature nitrogen gas temperature.This intelligent control approach greatly reduces the operational complexity, allowing researchers to focus more on the experiments themselves rather than equipment adjustments.
In order to understand the crystal structure change of the sample in the process of low temperature refrigeration.The medium temperature chamber is especially suitable for detection under low temperature conditions, various chemical, biological, and physical experiments, used in medical and health, food, chemical fields, and group instruments in laboratories of scientific research institutes of universities and colleges, which need to maintain low temperature Rapid cooling of the reaction kettle under certain conditions, cooling of low-temperature grinding tools, freezing processing fixtures and low-temperature testing machines.
