Two-zone Thermal Shock Test Chamber

The two-zone thermal shock test chamber is designed with two independent control rooms, one for low temperature and one for high temperature. The product is quickly transferred back and forth between the high and low temperature zones, allowing the product to withstand severe temperature changes in a short period of time.

• •The temperature recovery time period is short, and two temperature systems have achieved rapid sample temperature recovery time (less than 15 minutes).
• •It is in compliance with IEC 60068-2-14 Na and IEC 61747-5 testing standards.
• •Excellent temperature uniformity: The average airflow within the testing area generates an outstanding temperature distribution.
• •The chamber can be controlled and monitored remotely by mobile phones, tablets, and PCs.
• •Can customized the chamber’s volume, temperature and appearance on demand.
• •Operating system with multi-language system, can be switched according to the need.

The two-zone thermal shock test chamber simulating the extreme temperature shock that the product may encounter in actual use, the thermal shock chamber helps the R&D and QC teams to evaluate the reliability and performance of the product under harsh conditions.

The two-zone thermal shock test chamber is a special environmental testing equipment that can quickly test items under extreme temperature conditions. Its application areas are very wide, and the following are some common application areas:

• •Automotive industry: Testing the performance and reliability of automotive components, vehicles, and materials in cold and high temperature environment.
• •Aerospace industry: Testing the performance and reliability of aerospace equipment and devices under extreme temperature conditions to ensure their reliability during spaceflight.
• •Electronic components industry: Testing the performance and reliability of electronic components in cold and high temperature environment to ensure their reliability under various environmental conditions.
• •Medical device industry: Testing the performance and reliability of medical devices in cold and high temperature environment to ensure their reliability in medical settings.

These fields require a two-zone thermal shock test chamber to simulate temperature changes in actual usage environment, evaluate the performance, reliability, and durability of items, and provide valuable reference data for product design, production, and quality control.

The performance parameters of the two-zone thermal shock test chamber usually include temperature range, control system, working room size, heating time, cooling time, temperature fluctuation, temperature uniformity, etc.

• •RTCA DO-160: Environmental Conditions and Test Procedures for Airborne Equipment
• •SAE J1211: Environmental System Performance Testing for Automotive Electronic Devices
• •IEC 60068-2-14: Environmental testing - Part 2-14: Tests - Test N: Change of temperature.

• •ISO 16750: Road vehicles - Environmental conditions and testing for electrical and electronic equipmen.
• •IEC 60917: Modular order for the development of mechanical structures for electronic equipment practices.

The two-zone thermal shock test chamber also complies with testing standards such as IEC 61587-1, IEC 60601-1,IEC 60335-1, IEC 60721, etc

The controller system of Sanwood test chamber adopts world leading hardware and software systems to ensure that the test box operates under preset conditions, providing accurate and reliable experimental data to help users achieve precise control and data collection of various experimental conditions.

• •Controller: The TEMI 1500 controller imported from Sanwontech in South Korea and the self-developed Siemens control system are used, equipped with RS232, RS485, and Ethernet communication ports.
• •Programmable control: supports setting experimental programs, such as heating, cooling, holding time, etc., and executing multiple program settings.Support advance reservation for power on function.
• •Multiple languages optional: English, Korean, Russian, Chinese, and Japanese.
• •Remote monitoring: Using SAMWON-EZNET network remote technology to achieve remote control, the test chamber can be monitored at any time and emails can be sent to users' PCs and phones, enhancing convenience.

The specific control system of the test chamber may vary depending on the model, so it is necessary to carefully read the Sanwood Environmental Test Chamber Manual and follow safety operating procedures before use.

The refrigeration system of the test chamber is a complex and important system, and the quality of the refrigeration system is crucial for the accuracy and reliability of the test results.

• •Sanwood has developed hot air refrigerant defrosting technology, which effectively melts the frost on the evaporator by injecting high-temperature and high-pressure refrigerant vapor into the heat exchanger inside the test chamber. This not only ensures that the evaporator does not frost, but also greatly reduces the energy consumption of the equipment.
• •The refrigeration unit adopts international famous brands and cooperates with Japan's Eginomiya and the US Sporan to develop EPV series and XUP series quick opening solenoid valves for energy-saving systems, with an all-weather service life of over 15 years. And began to develop the new Danfoss AKV series throttling electronic expansion valve system, which is more efficient and energy-saving.
• •Optimizing the layout of the refrigeration system adopts VRF (refrigerant flow control) technology based on PID cold end output principle to achieve low-temperature energy-saving operation, which can reduce energy consumption by 30% under low-temperature conditions.
• •The refrigeration system adopts modular design, achieving low failure rate,less welding joints, high refrigeration efficiency, good reliability, simple maintenance, and low repair costs.
