Four Comprehensive Test Chambers

The four comprehensive environmental chambers compared to Agree Chamber that only have temperature, humidity and vibration factors, a four comprehensive chamber normally integrates altitude conditions to an agree chamber, for comprehensive test for the above-mentioned products.

• •Devices can be customized according to customer’s specific requirement.
• •Temperature change rate can be 5℃ to 30℃/min.
• •Compliant to MIL-STD 781 and 883 regulations.
• •Stable and accurate temperature and humidity performance.
• •Local installation and debugging teams can be arranged on-site for debugging and installation.
• •Operating system with multi-language system, can be switched according to the need.
• •It has programmable control function, can set fixed values/programs, can set different temperature and humidity change curves and test times.

The four comprehensive chamber is a device to obtain combined temperature, humidity, vibration and altitude conditions in one chamber, for function evaluation for analogue electronics, aerospace products, auto mobile and communication products, etc. Following are main application fields:

• •Electronics: To test and evaluate functions and reliability of electric parts for mobile phones, laptops, and chipset, etc., under different environmental conditions.
• •Auto Mobile: To test function and evaluate durability and reliability of engine, brake, tyres, gears, control units, control panel, etc., by simulating different environmental conditions.
• •Aerospace: To test performance of meters, control systems, aerospace materials, spare parts etc., under extreme environmental conditions.
• •Medical Devices: To test and study stability and reliability of packing and medical devices based on different environmental conditions.
• •Communication Device: To test communication device, such as Communication station or Routers in different environmental conditions, such as different temperature, humidity, air pressure and vibration conditions, to evaluate function and reliability of the devices.
• •New Energy: To test varies of new energy products such as (solar panel, wind generators, etc.) in different environmental conditions, to evaluate function and reliability of the devices, and to increase the device lifespan and working efficiency.

The four comprehensive chambers are usually used for function and reliability testing for materials or products in multiple extreme environmental conditions. Different products or materials may face to different testing standards. Following are popular standards that an four comprehensive chamber compliant to:

• •MIL-STD-810: US military test standards, which is widely used in military and aerospace area. Multiple environmental test methods are included.
• •IEC 60068-2-30：Environmental testing - Part 2-30: Tests - Test Db: Damp heat, cyclic (12 h + 12 h cycle).
• •ISO 16750：Road vehicles — Environmental conditions and testing for electrical and electronic equipment.
• •ISO 2233：Packaging-Complete, filled transport packages and unit loads-conditioning for testing.
• •SAE J1211：Recommended Environmental Practices for Electronic Equipment Design.
• •RTCA DO-160：Environmental Conditions and Test Procedures for Airborne Equipment.
• •IEC 60068-2-1：Environmental testing.
• •IEC 60068-2-6：Sinusoidal Vibration Testing.
• •RIEC 60068-2-2: Dry Heat Temperature Testing.

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.
