Introduction: A “Like” from the Chinese Academy of Sciences
Spring is in full bloom, and all things flourish. Recently, SCICOOLING’s “Spring Regular Customer Tour” visited a research institute of the Chinese Academy of Sciences. Faced with the 1.5m³ ultra-low temperature rapid temperature variable altitude test chamber delivered last November, the lab staff gave a thumbs up. This special non-standard equipment has operated stably for months with zero failures, becoming the main equipment for instrument and sensor testing in aerospace and satellite rocket fields, breaking industry technical bottlenecks with superior performance and demonstrating the solid strength of high-end domestic environmental test equipment.
Special non-standard: reaching the sky above and touching deep cold below
While the test chamber in conventional environments is still struggling against the -70°C low temperature limit and the 1kPa low pressure threshold, SCICOOLING’s non-standard altitude test chamber has elevated the track to a whole new level. With its disruptive single-compressor mechanical refrigeration technology, it achieves an astonishing -120°C ultra-low temperature, while pushing the pressure inside the chamber to an almost vacuum of 10Pa. Even more impressive is its overall performance: even in environments as low as 1kPa, it can maintain strict temperature control of -90°C, with a cooling rate as high as 5°C/min.
This is not just a set of cold data, but a perfect reproduction of the extreme environments of nearby spaces.
Technological breakthrough: Multi-purpose machine to replace liquid nitrogen
In the past, simulating ultra-low temperature tests often meant activating expensive liquid nitrogen consumption modes. Liquid nitrogen not only has high procurement costs, but storage and transportation also pose safety risks and efficiency bottlenecks. SCICOOLING’s equipment, with its robust capability of “mechanical refrigeration reaching -120°C/10Pa,” has successfully shed the label that “only liquid nitrogen can handle ultra-low temperature tests.” Industry experts point out that the performance of this equipment falls between conventional low-pressure and thermal vacuum devices, and it is widely used in near-space environments. It can be used in multiple devices (such as high and low temperature, low pressure, ultra-low temperature, and thermal vacuum tests) and can also replace some liquid nitrogen tests. Over the long term, the cost savings are considerable, truly achieving the goal of “running fast while saving money.”
(SCICOOLING uses cryogenic hybrid working fluid throttling refrigeration technology, eliminating the need for liquid nitrogen refrigeration; a single compressor can achieve mechanical cooling down to -190°C ultra-low temperature)
Case Testimonial: From aerospace and high-reliability industry to nuclear automobiles, multiple industries are using SCICOOLING. SCICOOLING’s outstanding performance is no coincidence, but a concentrated reflection of SCICOOLING’s years of technological accumulation. In the field of altitude test chambers, SCICOOLING has long leveraged mature technology and reliable quality to implement benchmark projects across multiple industries and clients. Its products widely serve aerospace, high-reliability equipment, semiconductors, new energy, third-party testing, research institutions, and many other fields.
