Product Introduction
Our company has long supplied ultra-low temperature test equipment ranging from -120℃ to -140℃ for projects including the China Academy of Launch Vehicle Technology, China Aerospace Research Institute, and environmental monitoring programs under the National 863 Project.
It simulates an environmental range of +150℃ to -70℃ for testing both civilian and military aerospace products.
It simulates an environmental range of +150℃ to -140℃ for simulating space environment tests of electronic components.
The equipment adopts PLC touchscreen control, featuring simple human–machine interaction and communication connection functions with the central control system.
The ultra-low temperature unit adopts an imported cascade ultra-low temperature compressor assembly and internationally renowned brand components, ensuring stable performance and reliable operation. It has an attractive appearance, low noise, low energy consumption, and high cost efficiency. Equipped with PLC touchscreen control, it supports intuitive human–machine dialogue and online communication with the control center.
It has replaced liquid nitrogen in many application fields. The power consumption cost of compressor refrigeration is only 5%–30% of that of liquid nitrogen refrigeration. It completely solves the difficulty of temperature difference control encountered with liquid nitrogen. The ultra-low temperature unit achieves precise temperature control with a temperature accuracy of approximately ±1℃.
