The chamber also includes proper ventilation and exhaust systems to manage any fumes or gases generated during testing, such as those from engine combustion or chemical exposure.
• Precision Environmental Control Systems
  • Temperature Control: Capable of maintaining a wide temperature range, from -40°C to +150°C, with an accuracy of ±1°C. It utilizes advanced refrigeration and heating technologies, such as industrial-grade compressors and high-power heating elements. The control system incorporates a feedback loop with multiple temperature sensors strategically placed throughout the chamber, ensuring uniform temperature distribution. The user-friendly control panel allows for precise programming of temperature profiles, including rapid temperature changes and extended soak times, mimicking real-world conditions like cold starts in winter or heat soak in traffic.
  • Humidity Control: The humidity control system can achieve humidity levels from 5% to 95% RH, with an accuracy of ±3% RH. It employs a combination of steam injection and dehumidification techniques, along with a carefully designed air circulation pattern. Humidity sensors continuously monitor the internal environment, and the control system adjusts accordingly to create the desired humidity levels. This is crucial for testing the effects of moisture on components, such as the corrosion of metal parts, the performance of electrical systems in humid conditions, or the durability of interior materials like upholstery and dashboard plastics.
  • Salt Spray and Chemical Resistance Testing: To simulate the corrosive effects of road salts and other chemicals, the chamber is equipped with a salt spray and chemical injection system. It can introduce controlled amounts of salt solutions, acid rain simulants, and other automotive-related chemicals into the testing environment. The chamber's interior is designed to resist corrosion from these substances, and the system allows for precise control of the concentration, duration, and spray pattern of the chemicals. This is essential for evaluating the durability of exterior body panels, chassis components, and undercarriage parts.

For example, a medium-sized chamber might have an interior volume of 10 cubic meters, with dimensions optimized for efficient air circulation and uniform environmental parameter distribution.
• Temperature Cycling Rate: Can perform temperature cycles at a rate of 2 to 5 cycles per hour, depending on the specific test requirements. For example, it can rapidly cool from +80°C to -20°C in a matter of minutes and then heat back up, subjecting the components to significant thermal stress, which is essential for evaluating thermal fatigue resistance.
• Humidity Cycling Rate: The humidity can be cycled within 15 to 30 minutes, allowing for the simulation of rapid changes in moisture conditions, such as transitioning from a dry desert environment to a humid rainforest-like atmosphere.
• Salt Spray Concentration and Exposure Time: The salt spray system can introduce salt concentrations ranging from 1% to 5% (by weight), and the exposure time can be set from a few hours to several weeks, depending on the desired test severity. This allows for the evaluation of the corrosion resistance of components under different levels of salt exposure.
• Dust Concentration and Particle Size: The dust injection system can generate dust concentrations from 10 milligrams per cubic meter to 1000 milligrams per cubic meter, and the particle size can be adjusted from fine powders to coarser sands, enabling the testing of components' ability to handle different types of particulate matter.
• UV Intensity and Exposure Duration: The UV lamps can produce intensities ranging from 0.5 W/m² to 1.5 W/m², and the exposure time can be precisely controlled from a few hours to several months, depending on the specific materials and components being tested. This allows for the assessment of the long-term effects of sunlight on automotive finishes and interior materials.
• Data Acquisition Rate: The data acquisition system samples sensor data at a rate of 500 samples per second, ensuring that even the most minute and rapid changes in temperature, humidity, chemical exposure, mechanical stress, or electrical parameters during the test are accurately recorded and can be analyzed in detail.
