Horizontal Two-Zone Thermal Shock Test Chamber
In the horizontal two-zone thermal shock test chamber, the two compartments are positioned side by side unlike traditional models, which have a stacked upper and lower design. This testing unit is used to evaluate how well materials, components, or equipment can withstand sudden temperature changes.
Application Fields of the Thermal Shock Test Chamber
The horizontal two-zone thermal shock test chamber is a vital tool for evaluating the performance and durability of materials and products across various industries. Its primary applications include:
- Electronics and Electrical: Assessing the reliability of electronic components, PCB circuit boards, and other parts under rapid temperature shifts.
- Aerospace: Simulating sudden temperature changes to test the resilience of aerospace systems and components.
- Automotive: Evaluating how automotive parts perform under extreme thermal conditions.
- Materials Science: Studying the physical and chemical behavior of materials such as plastics and metals during repeated heating and cooling cycles.
This chamber supports a wide range of testing needs, helping ensure that products continue to perform reliably under varying environmental conditions.
Test Standards for the Thermal Shock Test Chamber
The horizontal two-zone thermal shock test chamber conducts tests based on recognized international and national standards to ensure accurate and reliable results. Commonly followed standards include:
- MIL-STD-810: U.S. military standard for testing equipment performance under extreme environmental conditions.
- IEC 60068-2-14: International Electrotechnical Commission standard for evaluating electrical and electronic equipment under varying temperature conditions.
- MIL-STD-202: A U.S. military standard series for reliability testing of electronic components.
- ISO 16750: International Organization for Standardization standard for testing automotive electronic equipment under environmental stress, including temperature fluctuations.
- JIS C 0020: Japanese Industrial Standard for environmental testing of electrical and electronic devices, including thermal shock testing.
Test results from the horizontal two-zone chamber provide accurate insights into product performance in real-world conditions supporting both quality assurance and long-term reliability.

Control system features may vary by model. Always consult the Qualitest Environmental Test Chamber Manual and follow all safety guidelines before operation.
Refrigeration System of the Thermal Shock Test Chamber
The refrigeration system is a critical component of the test chamber, directly impacting the accuracy and reliability of test results.
- Qualitest has developed a hot air refrigerant defrost technology that melts frost on the evaporator by injecting high-temperature, high-pressure refrigerant vapor into the chamber’s heat exchanger. This prevents frost buildup and significantly reduces energy consumption.
- The refrigeration unit uses internationally recognized brands and collaborates with Japan and the U.S to develop the EPV and XUP series quick-opening solenoid valves, designed for energy-saving systems with a service life exceeding 15 years. Development is also underway for the more efficient Danfoss AKV series electronic expansion valves.
- The system layout is optimized with VRF (Variable Refrigerant Flow) technology, based on PID cold-end output control, enabling low-temperature energy-saving operation that cuts energy use by up to 30% in cold conditions.
- The modular refrigeration system design ensures fewer welds, a low failure rate, high cooling efficiency, easy maintenance, and reduced repair costs, providing reliable and cost-effective performance.
