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

• •Controller: It adopts the controller imported from South Korea Sanwon and the self-developed control system, which can be equipped with Siemens control system and equipped with RS232, RS485 and Ethernet communication ports.
• •Programmable control: It supports setting experimental programs, such as heating, cooling, constant temperature time, etc., and can execute multiple program settings, and supports advance reservation startup 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 the current data can be viewed through the user's PC and mobile phone, which improves the convenience of testing.

The specific control system of the test chamber will vary depending on the model. Please read the "Sanwood Environmental Test Chamber Manual" carefully before use and comply with the safety operating procedures.

The refrigeration system of the test chamber is a complex and important system. The stability of the refrigeration system is crucial to the accuracy and reliability of the test results.

• •Sanwood Technology has developed a refrigerant hot gas defrosting technology, which effectively melts the frost on the evaporator by injecting high-temperature and high-pressure refrigerant steam into the heat exchanger in 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 an internationally renowned brand. In cooperation with Japan's Saginomiya and the United States' Sporlan, the EPV series and XUP series energy-saving system quick-opening solenoid valves have been developed, with an all-weather service life of more than 15 years. And began to develop a new Danfoss AKV series throttling electronic expansion valve system, which is more efficient and energy-saving, and reduces noise.
• •Optimize the layout of the refrigeration system, and adopt VRF (refrigerant flow control) technology based on the 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 a modular design, with low failure rate, few welding points, high refrigeration efficiency, good reliability, simple maintenance, and low maintenance cost.
