Three-layer Temperature Test Chamber

Three-layer temperature test chamber with three independent test zones in vertical stack design. Maximize testing capacity while minimizing lab footprint, ideal for high-volume comparative testing and production verification.

• •Three independent test layers are vertically stacked, sharing the external framework and partial infrastructure, saving over 60% of laboratory floor space.
• •Each level is equipped with a fully independent refrigeration unit, heating system, circulation fan, and high-precision PID controller, ensuring simultaneous operation of different temperature conditions across all levels.
• •Each floor is equipped with a color touchscreen that supports independent programming, real-time monitoring, and data logging.

The three-layer high and low temperature test chamber is an indispensable test equipment in many industries, which helps in R&D, quality control and product certification.

• •Electronic and electrical industry: used to test the performance and reliability of electronic components, circuit boards, complete machines and other products under high and low temperature environments.
• •Automotive industry: Test the performance of automotive parts such as engines, batteries, body materials, etc. under extreme climate conditions to ensure that the car can maintain stable performance in various complex environments.
• •Aerospace industry: Test the performance of aircraft parts under extreme climate conditions to ensure that they can work normally under various environmental conditions.

The working principle of the high and low temperature test chamber is mainly based on cooling and heating cycles, which control the temperature inside the equipment through these cycles to simulate different high and low temperature environments.

• •MIL-STD-810: US military standard, involving a variety of environmental tests, including high and low temperature test methods, very suitable for military and aerospace products.
• •ISO 16750: An automotive industry standard that provides requirements for testing automotive electronic components under different environmental conditions, including temperature and humidity changes.
• •SAE J1211: A standard for automotive electronic components that covers reliability testing under extreme temperatures.

It also complies with IEC 60571, NB/T 31004, GJB 150, IEC, MIL and other test standards.

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.
