• •High precision temperature recovery for faster recovery of required conditions.
• •Energy-saving design, self-developed refrigeration control system, reduce 30% of store consumption.
• •Remote control and monitoring on mobile phones, tablets and PCS.
• •Can customized the chamber’s volume, temperature and appearance on demand.
• •Comply with Japanese standards JASO D-014-4 and EIAJ ED-2513B Na, as well as various grades of MIL-STD-883H and 202G.

The three-zones thermal shock test chamber ideal for vibration-sensitive measuring instruments and sensors, as well as energized samples.

The three-zones thermal shock test chamber is a kind of special environmental test equipment, which can quickly test items under extreme temperature conditions. Its application areas are very wide, 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.
• •Machinery and equipment industry: Testing the performance and reliability of machinery and equipment in cold and high temperature environments to ensure its reliability in industrial production.

The three-groove thermal shock test chamber is required to simulate the temperature change in the actual use environment, evaluate the performance, reliability and durability of the item.

The important performance parameters of the three-zones thermal shock test chamber usually include temperature range, control system, studio 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 14971: Medical devices - Application of risk management to medical devices.
• •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.
