1. Product Name and Purpose

2. Product Features

• Spacious and Robust Construction
  • The chamber is constructed with a heavy-duty, high-strength alloy framework that is specifically engineered to withstand the rigors of both the testing process and the extreme conditions it simulates. The exterior shell is fabricated from corrosion-resistant materials, ensuring long-term durability and protection against the elements. The interior is lined with a thermally conductive and chemically inert material that promotes uniform temperature distribution and minimizes any potential interference with the tested samples. The door is a precision-engineered component, featuring a multi-point locking system and a high-quality sealing gasket. This ensures an airtight and hermetic seal, preventing any leakage of conditioned air and maintaining the integrity of the simulated environment. A large, reinforced viewing window, made of tempered and anti-fog glass, allows for real-time visual inspection of the testing process without compromising the chamber's environmental control.
• Precision Temperature and Humidity Control Systems
  • Temperature Control: Capable of maintaining an extensive temperature range, from -70°C to +150°C, with an astonishing accuracy of ±0.5°C. This is achieved through a combination of advanced refrigeration technologies, including cascade refrigeration for ultra-low temperature capabilities, and high-power heating elements. The control system is a marvel of engineering, incorporating a sophisticated feedback loop with multiple strategically placed temperature sensors throughout the chamber. This not only ensures uniform temperature distribution but also enables rapid and precise temperature transitions. The user-friendly control panel permits the programming of complex temperature profiles, including rapid temperature ramps, extended dwell times at specific temperatures, and intricate cycling sequences, all of which are essential for replicating the dynamic temperature changes experienced in aerospace and defense applications.
  • Humidity Control: The humidity control system is equally impressive, with the ability to achieve and maintain humidity levels ranging from 5% to 95% RH (Relative Humidity), with an accuracy of ±3% RH. It employs a combination of steam injection humidifiers and desiccant dehumidifiers, integrated with a carefully designed air circulation system. The chamber is equipped with high-precision humidity sensors that continuously monitor the internal humidity. The control system then makes real-time adjustments to the humidification or dehumidification processes, allowing for the creation of stable or rapidly changing humidity environments. This is crucial for testing the effects of moisture on sensitive electronic components, such as circuit boards and connectors, as well as the integrity of materials like composites and metals in humid conditions.

The chamber's size allows for the testing of larger assemblies, such as complete avionics racks, small satellite subsystems, or multiple military vehicle electronics components simultaneously, providing a more comprehensive and realistic testing environment.
• Temperature Cycling Rate: The chamber can perform temperature cycles at a rate of 2 to 5 cycles per hour, depending on the specific requirements of the test protocol. For example, it can rapidly cool from +80°C to -50°C in a matter of minutes and then heat back up, subjecting the samples to significant thermal stress. This is essential for evaluating the resistance of components to thermal fatigue, which is a critical factor in the long-term reliability of aerospace and defense equipment.
• Humidity Cycling Rate: The humidity can be cycled within 15 to 30 minutes, allowing for the simulation of rapid changes in moisture conditions. This replicates the transitions that may occur, for example, when an aircraft moves from a dry, high-altitude environment to a humid, low-altitude landing zone or when a military vehicle traverses different climatic regions.
• Data Acquisition Rate: The data acquisition system samples sensor data at a rate of 200 samples per second, ensuring that even the slightest and most rapid changes in temperature, humidity, pressure, or vibration during the test are accurately recorded. This high sampling rate provides engineers and scientists with detailed and accurate information about the performance and behavior of the tested samples, enabling them to identify potential issues and make informed design improvements.
• Compliance with Industry Standards: The chamber is fully compliant with MIL-STD-810, which covers a wide range of environmental conditions and test methods relevant to military equipment. It also adheres to RTCA/DO-160, which focuses specifically on the environmental testing of avionics. This compliance ensures that the testing is conducted in accordance with the strict requirements and procedures established by the aerospace and defense industries, providing confidence in the reliability and performance of the tested products.
