2. Product Features

• Robust and Explosion-proof Chamber Structure
  • The test chamber is constructed with a heavy-duty, explosion-proof steel frame and walls. The materials and design are in accordance with international explosion-proof standards, such as ATEX and IECEx. The chamber is sealed with high-quality, flame-retardant gaskets and advanced sealing mechanisms, ensuring a leak-proof environment during testing. The door is equipped with a reliable locking system and a pressure-resistant viewing window, allowing operators to closely monitor the test process without compromising safety. The interior of the chamber is designed to withstand the shockwaves and pressure generated during a potential explosion.
• Precision Temperature and Humidity Control System
  • The heart of the chamber lies in its advanced temperature and humidity control system. It can achieve a wide temperature range, typically from -40°C to +80°C, with an accuracy of ±0.5°C. The humidity control range extends from 20% to 95% relative humidity, with an accuracy of ±3% RH. The system utilizes high-performance refrigeration units, electric heaters, humidifiers, and dehumidifiers, all coordinated by a sophisticated PID controller. Temperature and humidity sensors are strategically placed within the chamber to provide real-time feedback, enabling the control system to make instantaneous and accurate adjustments.
• Explosion-proof Electrical and Instrumentation System
  • The chamber is equipped with a fully explosion-proof electrical and instrumentation system. All electrical components, including motors, heaters, sensors, and control panels, are designed and certified to operate safely in explosive atmospheres. The wiring is installed in explosion-proof conduits, and the control system is designed to prevent any sparks or arcs that could ignite the explosive mixture. The instrumentation system includes pressure sensors, gas detectors, and temperature and humidity transmitters, all of which are explosion-proof and provide accurate and reliable data for monitoring and controlling the test conditions.
• Intuitive Control Panel and Data Acquisition Interface
  • The equipment is equipped with an intuitive control panel that simplifies the operation and parameter setting. Operators can easily adjust the temperature, humidity, test duration, and other parameters using the user-friendly interface. The control panel also provides real-time displays of the current test conditions, as well as any alarms or warnings. The chamber is integrated with a comprehensive data acquisition system. It records all relevant test data, such as temperature and humidity histories, pressure profiles, and any observable changes in the test samples. 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.
• Versatile Sample Fixturing and Placement
  • The interior of the chamber is designed to accommodate a wide variety of sample sizes and shapes. It can be equipped with adjustable racks, trays, and custom-made holders to ensure proper positioning and exposure of the test samples. The sample fixturing is made of materials that are resistant to the test conditions and do not contaminate the explosive atmosphere. This flexibility allows for the testing of different products, from small electronic components to large industrial equipment or chemical containers. For example, a sensor can be mounted on a holder to test its performance in a humid and explosive environment, while a chemical reactor can be placed on a rack to evaluate its integrity under temperature and pressure fluctuations.

3. Specific Parameters

• Maximum Temperature Swing and Accuracy
  • With a temperature range spanning from -40°C to +80°C, the chamber can achieve a maximum temperature swing of 120°C. The accuracy of ±0.5°C ensures that the test conditions are precisely maintained, providing reliable and repeatable results. This wide temperature spectrum is crucial for testing products that may be exposed to extreme cold, such as in cryogenic storage facilities in the petrochemical industry, or extreme heat, like in industrial ovens used in food processing plants in potentially explosive environments.
• Humidity Range and Rate of Change Accuracy
  • The humidity range of 20% to 95% RH, with a rate of change accuracy of ±3% RH, allows for a comprehensive evaluation of the effect of moisture on products. The ability to precisely control the humidity level and its rate of change helps in understanding how products respond to different moisture environments, such as the drying process of pharmaceuticals or the condensation that may occur in a humid chemical plant.
• Explosion-proof Rating and Certification
  • The chamber is certified to meet specific explosion-proof ratings, such as Ex d (flameproof enclosure), Ex e (increased safety), or Ex p (pressurized enclosure), depending on the application and the nature of the explosive atmosphere. These certifications ensure that the chamber can safely contain any potential explosions and prevent the spread of flames and pressure waves outside the chamber. The explosion-proof rating is determined based on the type of explosive gas or dust, the maximum pressure that can be generated, and the temperature class of the environment.
• Testing Volume and Payload Capacity
  • The chamber offers a customizable testing volume, with options ranging from 1 m³ to 20 m³. The payload capacity can be adjusted according to the size and weight of the test samples, with a maximum capacity of up to 2000 kg. This allows for the testing of a significant number of samples or larger and heavier products. For example, in the mining industry, multiple samples of mining equipment or explosives can be tested simultaneously, saving time and resources.
• Data Sampling Frequency and Resolution
  • The data acquisition system samples data at a frequency of up to 50 Hz, providing a detailed record of the temperature, humidity, pressure, and other parameters. The resolution of the temperature data is 0.1°C, the humidity data is 0.1% RH, and the pressure data is 0.1 kPa. This high-resolution data is invaluable for identifying subtle trends and potential failure points, allowing for a more accurate assessment of product performance.

4. Product Functions

• Accurate Simulation of Explosive and Climatic Conditions
  • The primary function of the chamber is to provide a precise and reliable simulation of a combination of explosive and climatic conditions. By subjecting products to controlled temperature, humidity, and explosive atmospheres, it allows manufacturers and researchers to evaluate their performance and durability. This is crucial for ensuring the safety and reliability of products such as sensors, control systems, and industrial equipment in potentially explosive environments. For example, a gas sensor can be tested to ensure that it functions accurately in a humid and explosive gas mixture, providing early warning of potential hazards.
• Product Design Optimization and Quality Control
  • Through a series of tests on different product prototypes, the data obtained from the chamber can be used to optimize product designs. Engineers can analyze the behavior of various materials and components under explosive and climatic stress and make modifications to enhance the product's overall performance and safety. The chamber also serves as a vital tool for quality control, ensuring that each batch of products meets the required safety and performance standards. For instance, in the manufacturing of electrical equipment for petrochemical plants, testing in the explosion-proof chamber can help detect any weaknesses in the insulation or enclosure, leading to improvements in product quality.
