Walk-In High & Low Temperature and Humidity Test Chamber

The inside chamber of the walk-in constant temperature and humidity test room can maintain the temperature and humidity values set by the user, and these temperature and humidity values can also be alternately changed through program settings. Used to test and determine the heat resistance, cold resistance, dry resistance, and moisture resistance of electrical, electronic, and other products and materials. It is widely used in industries such as electronics, electrical appliances, communication, instrumentation, vehicles, plastic products, metals, food, chemistry, building materials, medical, aerospace, etc.

Description

Core Technical Advantages

  • Temperature Control Precision: PID microcomputer control system, emphasizing minimal fluctuations
  • Uniformity: Unique air duct design (such as multi-blade circulating fans), ensuring consistent temperature and humidity in every corner of a large space.
  • Energy Efficiency Technology: Featuring variable frequency compressors or electronic expansion valves, it is energy-saving and cost-effective (reducing operating costs).
  • Material and Craftsmanship: Using stainless steel (SUS#304) inner liner, high-density polyurethane insulation layer, and modular assembly method for the storage board.

Safety & Reliability

  1. Personnel safety: Internal emergency escape door locks, obstruction prevention alarm.
  2. Equipment protection: Independent over-temperature protection switch, compressor overload protection, water shortage/dry burn protection, pressure relief port.
  3. Explosion-proof configuration: Gas sensor, explosion-proof door lock and explosion-proof window.

    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.

    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.

    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.
