There’s an old buddy in Chengdu

In today’s rapidly updated industrial equipment, we have become accustomed to “replace what is broken.”

But in the workshop of an electronics factory in Chengdu, there is an “old buddy” that shatters many people’s expectations. It is a temperature test chamber. From April 2008 until now, for a full 17 years and 6 months, over 6,385 days and nights, it has been operating normally. “This high-temperature temperature chamber has longer service experience than many of our senior employees!” Just after National Day, we encountered staff from SCICOOLING’s Southwest Service Center during the inspection. The client’s lab staff sincerely praised, “We never expected that an ordinary piece of equipment costing tens of thousands could last 17 years!” Looks like running for a few more years won’t be a problem.”

Seventeen years of perseverance, the secret lies in “hardcore” internal strength. Looking back at 2008: the grand opening of the Beijing Olympics, smartphones were just emerging, and Xiaomi Group had not yet been established. That same year, SCICOOLING Beijing Company, which had emerged from the pilot workshop of the Institute of Physics and Chemistry of the Chinese Academy of Sciences, was officially established. This temperature test chamber entered service as one of the company’s first products. Its inner chamber is 30L, with a temperature range of -75°C~150°C, and a heating rate of ≥2°C/min. Notably, this high-low temperature chamber uses SCICOOLING’s innovative hybrid refrigeration technology, which won the second prize of the National Technology Invention Award in 2006. It can achieve -75°C cooling using only a single compressor for mechanical cooling. The installed power is only 2KW, and a 220V power cable is sufficient. Compared to traditional compressor stacking technology, it greatly reduces operating energy consumption, saves installation space, and reduces the number of weld points and accessories, resulting in stronger stability.

In addition to adopting advanced refrigeration technology, all components of the SCICOOLING test chamber are carefully selected, with core components mostly imported brands, including compressors, temperature sensors, solenoid valves, controllers, relays, and more. At the same time, the entire machine assembly process is meticulously refined, strictly controlling quality to ensure that before leaving the factory, it fully meets or even exceeds customer technical specifications. In terms of service, SCICOOLING conducts free annual inspections of customers’ on-site equipment, enabling early warning, early detection, and early resolution of any issues.

Time is the best touchstone. Since its founding in 2005 as a pilot workshop at the Institute of Physics and Chemistry, Chinese Academy of Sciences, SCICOOLING has been deeply involved in the environmental test equipment industry for 20+ years, but its pursuit of excellence in quality has never wavered. From materials science to process manufacturing, from control systems to energy efficiency optimization, every advancement is made to ensure every customer investment is worth the money. Look at this high- and low-temperature dual-axis rotary table with a warming box, running continuously for 15+ years without major repairs, relocating machines to multiple sites and operating normally. Since entering service in December 2010, currently in a laboratory of an aerospace system enterprise in Chongqing, its inner chamber volume is 125L, with a temperature control range of -60°C ~ 150°C.

Look at this fast temperature change temperature test chamber, 14+ years of continuous operation, temperature field indicator annual inspection in one go. Since November 2011, it has been in service and is currently at a CETC research institute. Its inner chamber volume is 512L, with a temperature control range of -80°C ~ 145°C and a heating rate of ≥5°C/min.
