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.
The standard floor load capacity is 500Kg/m³. However, we also provide specialized load-bearing customization to accommodate heavy specimens such as complete vehicles, large heavy machinery, or dense battery racks.
The standard power supply requirement is AC380V±10% 50HZ, three-phase four-wire with a protective grounding wire. Custom electrical configurations can be engineered to match local power grid standards in your region.
The inner lining is made of SUS304 high-grade stainless steel to ensure durability and corrosion resistance. The outer structure is made of plastic steel plate, with high-density polyurethane foam and glass fiber used for thermal insulation.
