FAQ
-
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 temperature and humidity chambers use environmentally friendly refrigerants R404a and R23 in a cascaded refrigeration system. These refrigerants comply with international environmental standards. The fully enclosed or semi-enclosed compressor design also minimizes refrigerant leakage risk, ensuring both environmental responsibility and long-term operational reliability.
-
Our chambers deliver industry-leading precision: temperature fluctuation is ±0.5℃, temperature uniformity is ±2.0℃, humidity fluctuation is ±2.5% R.H, and humidity uniformity is ±5% R.H. The advanced PID microcomputer control system continuously monitors and adjusts conditions to maintain these tight tolerances throughout the entire test cycle, ensuring highly repeatable and reliable results.
-
Yes. The LCD color touch screen controller supports both Chinese and English displays and includes built-in program and communication functions. The system supports external data logging interfaces, allowing seamless integration with your laboratory management software or remote monitoring platforms. This enables real-time tracking of temperature, humidity, and alarm status throughout your testing process.
