    ❓ Frequently Asked Questions
    • Absolutely. Our walk-in chambers feature a modular "sandwich" panel construction, allowing us to design the internal volume and external dimensions to your exact requirements. Whether you need a compact 2m³ room or a massive 100m³+ facility for vehicle testing, we can tailor the height, width, and depth to optimize your lab space. We also offer custom door sizes and reinforced flooring for heavy specimens.
    • This is a critical factor in AI server and EV battery testing. Our systems are engineered with High-Capacity Refrigeration Units and advanced PID control logic to compensate for "active heat loads." During the technical consultation, we calculate your specimen's maximum wattage (e.g., 5kW, 10kW+) to ensure the cooling system is sized correctly to maintain your target temperature even when the product is running at full power.
    • Safety is our top priority. All our walk-in chambers are equipped with an Internal Emergency Release Handle (glow-in-the-dark) that allows personnel to exit even if the door is locked from the outside. Additionally, we install Emergency Stop buttons inside the chamber, an Internal Lighting system, and audio-visual alarms to alert outside operators in case of an incident. For high-risk testing, oxygen sensors and view-windows are also available.
    • Our walk-in chambers support a maximum test temperature of up to 150℃ and a minimum test temperature as low as -70℃, depending on configuration. The humidity range covers 20%–95% R.H., with precise fluctuation control of ±0.5℃ for temperature and ±2.5% R.H. for humidity, making them suitable for a wide range of environmental simulation tests.
    • Our chambers use environmentally friendly refrigerants R404a and R23 in a stacked compressor configuration. Both air-cooled and water-cooled options are available, and the compressors can be fully enclosed or semi-enclosed depending on your application requirements. This design ensures efficient and reliable cooling across all operating conditions.
    • The chambers are equipped with an LCD color touch screen controller supporting both Chinese and English display. It features programmable test profiles, real-time monitoring, and communication functions for remote data logging and integration with external systems. This makes it easy to set up complex test cycles and monitor performance throughout the test duration.
