Low Pressure Climatic Test Chamber Customized for Hypobaric Environments

1. Product Name and Purpose

2. Product Features

• Robust and Airtight Chamber Construction
  • The low pressure chamber is constructed with a heavy-duty steel frame that provides exceptional strength and rigidity. The chamber walls are made of high-strength alloy materials that can withstand the significant pressure differentials. The interior is carefully sealed with advanced sealing technologies, such as double O-ring seals and vacuum-tight gaskets, ensuring an airtight enclosure. The door is designed with a reliable locking mechanism and a pressure-assisted sealing system to maintain the integrity of the low pressure environment. The chamber is also equipped with safety valves and pressure relief systems to prevent over-pressurization and ensure the safety of operators and the equipment.
• Precision Pressure Control System
  • The chamber features a highly accurate pressure control system. It can achieve a wide range of pressure levels, from near-vacuum conditions, typically as low as 10^-6 torr, to pressures equivalent to high-altitude environments, such as 10 kPa or higher. The system utilizes advanced vacuum pumps, pressure regulators, and sensors. The sensors continuously monitor the pressure inside the chamber and provide real-time feedback to the control unit. The control unit then adjusts the pumping rate and valve settings to maintain the desired pressure level with an accuracy of ±0.1% of the set value. This level of precision allows for highly controlled and repeatable experiments.
• Temperature and Humidity Regulation Capabilities
  • In addition to pressure control, the chamber also offers the ability to regulate temperature and humidity. The temperature can be maintained within a range of -40°C to +150°C, with an accuracy of ±0.5°C. The humidity control range extends from near-zero dryness to saturated conditions, with an accuracy of ±2% RH. Temperature and humidity can have significant impacts on the behavior of materials and biological samples under low pressure. The chamber's control system ensures that these environmental factors are precisely controlled, providing a more comprehensive simulation of real-world conditions.
• Intuitive Control and Data Acquisition Interface
  • The equipment is equipped with an intuitive control panel that allows operators to easily set and adjust the pressure, temperature, humidity, and test duration. The control panel also provides real-time displays of the current values of these parameters, 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 pressure profiles, temperature and humidity histories, and any changes in the physical properties of 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 Monitoring Options
  • The interior of the low pressure chamber is designed to accommodate a variety of sample sizes and shapes. It can be equipped with adjustable racks, trays, and holders to ensure proper sample positioning and exposure. The chamber is also fitted with observation windows and ports for connecting external monitoring and measurement devices. This allows for real-time monitoring of the samples during the test, such as the measurement of gas emissions, mechanical deformation, or biological responses. The sample fixturing is made of materials that are compatible with the low pressure and other environmental conditions and do not contaminate the test environment.

3. Specific Parameters

• Pressure Range and Accuracy
  • The chamber can maintain a pressure range from 10^-6 torr to 10 kPa or higher, with an accuracy of ±0.1% of the set value. This wide range enables the simulation of conditions from deep space vacuum to high-altitude flight. For example, in aerospace testing, components like aircraft cabin pressurization systems or satellite electronics can be tested under the exact pressure conditions they will encounter in operation.
• Temperature Range and Rate of Change
  • The temperature range of -40°C to +150°C allows for the simulation of a diverse range of climatic and thermal conditions. The rate of temperature change can be adjusted up to 10°C per minute. This rapid temperature change capability is useful for testing the thermal stability of materials and systems in combination with low pressure exposure. For instance, in the development of new materials for space exploration, their performance under rapid temperature swings in a low pressure environment can be evaluated.
• Humidity Range and Rate of Change
  • The humidity range of near-zero to saturated conditions, with a rate of change of up to 5% RH per minute, provides a comprehensive assessment of the effect of moisture on low pressure processes. High humidity can affect the behavior of biological samples or cause condensation issues on materials, while low humidity can lead to drying and cracking. The ability to control humidity precisely helps in understanding the complex interactions between low pressure, temperature, and humidity.
• 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 5000 kg. This allows for the testing of a significant number of samples or larger and heavier products. For example, in the aerospace industry, full-scale aircraft components or even small spacecraft modules can be tested.
• Pumping Speed and Vacuum Integrity
  • The chamber is equipped with high-performance vacuum pumps that can achieve rapid evacuation to the desired low pressure levels. The pumping speed can be adjusted depending on the specific test requirements. The vacuum integrity of the chamber is maintained over time, with a leakage rate of less than 10^-9 mbar·L/s. This ensures that the low pressure environment remains stable and accurate throughout the testing period.
