Sanwood Sanwood Comprehensive Environmental Chamber delivers unprecedented testing efficiency by integrating four critical environmental stress factors—temperature, humidity, vibration, and atmospheric pressure—into one advanced, synchronized platform.

• •A single chamber simultaneously or sequentially applies precise thermal, humidity , vibration , and altitude/pressure stresses.
• •Collects and correlates performance data across all environmental factors in one timeline, providing clear insight into failure mechanisms and product margins.
• •Saves significant floor space, reduces specimen handling, and accelerates test cycles compared to using separate, disconnected test equipment.
• •Local installation and debugging teams can be arranged on-site for debugging and installation.

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.
• •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.

• •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 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 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.
• •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.
