Walk In Environmental Test Chambers Meets DIN 75 220 Standard For Ageing

1. Product Name and Purpose

2. Product Features

• Tailored Chamber Design for Automotive Components
  • The chamber is constructed with dimensions and an interior layout that can accommodate a wide variety of automotive components, from small electronic parts to larger trim pieces and assemblies. The walls are made of high-strength, corrosion-resistant materials that provide excellent insulation and durability. The door is engineered with a precision sealing mechanism and a large viewing window, allowing operators to closely monitor the testing process without interfering with the internal environment. The interior is equipped with adjustable racks and fixtures to ensure proper positioning and exposure of the test samples.
• High-Fidelity Solar Simulation System
  • At the core of the chamber's capabilities is a state-of-the-art solar simulation system that complies with the requirements of DIN 75 220. It can accurately replicate the spectral distribution and intensity of natural sunlight. The system is capable of generating solar irradiance levels ranging from 200 W/m² to 1200 W/m², with a spectral match to natural sunlight within a narrow tolerance. High-intensity xenon or metal halide lamps are used, along with advanced optics and filters, to ensure uniform and accurate solar radiation across the entire testing area. This allows for a precise evaluation of how automotive components respond to solar-induced ageing, such as color fading, material degradation, and loss of mechanical properties.
• Precision Temperature and Humidity Control
  • The chamber is equipped with a sophisticated temperature and humidity control system. It can achieve a wide temperature range, typically from -40°C to +80°C, with an accuracy of ±0.3°C. The humidity control range extends from 10% to 95% relative humidity, with an accuracy of ±2% RH. The system utilizes high-performance refrigeration units, heaters, humidifiers, and dehumidifiers, all coordinated by a precise PID controller. Multiple sensors are strategically placed throughout the chamber to provide real-time feedback, enabling the control system to make rapid and accurate adjustments to maintain the desired environmental conditions. This precise control is crucial for simulating different climate zones and weather conditions that automotive components may encounter.
• Intuitive Control Panel and Data Acquisition Interface
  • The control panel of the chamber is designed for ease of use and operator convenience. It features a clear and intuitive interface that allows operators to set and adjust parameters such as solar irradiance, temperature, humidity, and test durations with minimal effort. The control panel also provides real-time displays of the current environmental conditions, as well as any alarms or warnings. The chamber is integrated with a comprehensive data acquisition system. It records all relevant test data, including temperature and humidity histories, solar radiation exposure levels, and any observable changes in the automotive components. The data can be stored in a built-in memory or exported to external storage devices for further analysis. The system can also generate detailed test reports in various formats, facilitating easy documentation and sharing of results.
• Safety Features and Alarms
  • To ensure the safety of operators and the integrity of the testing process, the chamber is equipped with a range of safety features. These include over-temperature and over-current protection, emergency stop buttons, and alarms for abnormal temperature fluctuations, humidity levels, solar radiation intensity, or equipment malfunctions. The safety features are designed to prevent damage to the chamber, the test samples, and the surrounding environment, providing peace of mind during the testing operation. Additionally, the chamber is designed with proper ventilation and exhaust systems to handle any potentially harmful gases or vapors generated during the testing process.
