Customization Process of Walk-in Environmental Test Chambers: A Professional Guide from Requirement to Delivery
Dec 03, 2025
As core equipment for industrial testing, the customization level of walk-in environmental test chambers directly determines testing accuracy and efficiency. This article breaks down the entire process from requirement communication to final delivery, helping enterprises clearly grasp the key nodes of customization.
1. Accurate Requirement Communication: Clarify Core Parameters
The first step in customization is to define core technical parameters, which lay the foundation for subsequent design.
Size Range: Covering small test spaces of 4m³ to large walk-in test chambers of 260m³, the size should be determined based on the volume, quantity of test samples and operational space requirements.
Temperature & Humidity Range: It can generally achieve temperature control of -70℃~+180℃ and humidity control of 30%R.H~98%R.H. For special scenarios, the range can be further expanded to -73℃~+177℃ (integral type).
Control Method: Multiple options are available, from basic microchip LED displays to PLC programmable logic controller touch screens, and can also be upgraded to remote centralized control systems to meet different operation and management needs.
Structure Type: Selection should be based on application scenarios, with parameters of three mainstream types as follows:
Test Type
Temperature Range
Humidity Range
Temperature Change Rate
Integral Type
-73℃~+177℃
30%~95%RH
4~5℃/min, or faster
Assembled Type
-68℃~+85℃
30%~95%RH
1~2℃/min
Steady-state Type
-20℃~+50℃
30%~95%RH
N/A
2. Scheme Design & Confirmation: Balance Professionalism and Practicality
After clarifying requirements, the technical team will issue a customization scheme, which mainly includes three parts:
Structural Design: Based on size and type, plan the layout of the test chamber's door, observation window and sample rack to ensure operational convenience and airtightness.
System Matching: Equip with corresponding refrigeration, heating, humidification and dehumidification systems to ensure temperature and humidity control accuracy, and configure hardware and software according to the control method.
Compliance Verification: The scheme must conform to relevant industry standards (such as GB/T, IEC, etc.), and confirm with the customer whether it needs to meet specific industry testing specifications.
After scheme confirmation, detailed drawings and technical agreements will be generated to clarify the rights, obligations and delivery standards of both parties.
3. Production & Manufacturing: Strictly Control Process and Quality
Entering the production stage, the process will be controlled around the two cores of "accuracy" and "stability":
Core Component Procurement: Select high-reliability compressors, sensors, controllers and other core components to ensure long-term operational stability of the equipment.
Modular Production: Assembled equipment adopts modular manufacturing to reduce on-site installation errors; integral equipment undergoes integrated assembly and preliminary debugging.
Factory Inspection: Each piece of equipment must undergo no-load temperature and humidity calibration and operational stability testing. Only after confirming that the parameters meet the design requirements can shipment be arranged.
4. Installation, Commissioning & Delivery: Ensure On-site Application
After the equipment arrives at the site, the professional team will provide full-process services:
On-site Installation: Carry out equipment positioning, pipeline connection and circuit debugging according to site conditions; for assembled equipment, ensure airtight connection of each module.
Accuracy Calibration: Combine the customer's testing needs, use professional instruments to perform on-site calibration of temperature and humidity uniformity and fluctuation to ensure compliance with test requirements.
Training & Delivery: Provide equipment operation and maintenance training for the operation team, and deliver technical materials such as operation manuals and calibration reports to complete the final acceptance.
