FAQ
-
Q Can the walk-in chamber dimensions be customized to fit my specific facility?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.
-
Q How does the chamber maintain stability if my test specimen generates significant heat?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.
-
Q What safety features are in place to protect personnel working inside the chamber?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.
-
Q What temperature and humidity ranges can the walk-in chamber achieve?Our walk-in temperature and humidity chambers support a maximum test temperature of up to 150℃ and a minimum test temperature as low as -70℃, with a humidity range of 20–95% R.H. The precise range can be customized based on your specific testing requirements and industry standards.
-
Q What industries and applications are your walk-in chambers most suitable for?Our chambers are widely used across automotive (weather resistance testing for full vehicles), new energy and EV battery (extreme environment cycling), electronics and communication equipment (full-load aging tests), and photovoltaic/aerospace sectors (long-life simulation). If your industry is not listed, please contact us — we offer tailored solutions for virtually any environmental simulation requirement.
-
Q What refrigerants and compressor types are used, and are they environmentally friendly?We use environmentally friendly refrigerants R404a and R23, combined with air-cooled or water-cooled, fully enclosed or semi-enclosed stacked compressors. Our systems are designed to meet international environmental compliance standards, minimizing ecological impact while delivering reliable, high-performance cooling for demanding test applications.
