      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.     Would you like me to supplement an English Version of Walk-in Environmental Test Chamber Customization Requirement Confirmation Form? It will list key parameter check items and common questions to facilitate quick alignment of requirements between you and your customers.

• Differences Between High-Low Temperature Test Chamber and Thermal Shock Chamber

  Nov 26, 2025

  In industrial product reliability testing, high and low temperature test chambers and temperature shock test chambers are core environmental testing equipment, both simulating extreme temperatures to verify product durability. However, they differ fundamentally: the former focuses on gradual temperature-humidity cycles, while the latter on instantaneous thermal shock. Clarifying these differences is key to matching test needs and ensuring data validity. 1. Rate High-Low Temperature Test Chamber: Slow, with a regular rate of 0.7∼1 ℃/min, and rapid versions can reach 5∼15 ℃/min. Thermal Shock Chamber: Abrupt, with instant switching. 2. Structure High-Low Temperature Test Chamber: Single-chamber structure, integrating heating, refrigeration, and humidification functions. Thermal Shock Chamber: Multi-chamber structure, including high-temperature chamber, low-temperature chamber, and test chamber. 3. Temperature Continuity High-Low Temperature Test Chamber: The temperature changes smoothly without any "shock sensation". Thermal Shock Chamber: The temperature changes by leaps and bounds, with a common temperature range of −40∼150℃. 4. Application High-Low Temperature Test Chamber: Suitable for temperature endurance testing of general products such as electronic devices, household appliances, and building materials. Thermal Shock Chamber: Suitable for shock resistance testing of temperature-sensitive products such as automotive electronics, semiconductors, and aerospace components. 5. Core Position & Test Purpose High-Low Temperature Test Chamber: Simulates gradual temperature (and humidity) changes to test product stability under slow thermal variation (e.g., electronic devices’ performance after gradual cooling to -40℃ or heating to 85℃). Thermal Shock Chamber: Simulates abrupt temperature switching (≤30s transition) to test product resistance to extreme thermal shock (e.g., auto parts adapting to drastic day-night temperature changes, aerospace components’ tolerance to sudden high-low temperature shifts). Summary The high and low temperature test chamber is a "slow-paced endurance test", while the temperature shock chamber is a "fast-paced explosive power challenge". Just based on whether the product will encounter "sudden cold and heat" in the actual usage scenario, the precise selection can be made.

• How to Choose the Right Thermal Shock Chamber: Water-Cooled or Air-Cooled?

  Nov 24, 2025

  When selecting between water-cooled and air-cooled types of thermal shock chambers, a comprehensive evaluation must be conducted based on core factors such as test requirements, site conditions, and budget constraints. These two types exhibit significant differences in performance, installation, maintenance, and other aspects. Below is a detailed selection guide: I. Cooling Principle Water-cooled thermal shock test chambers dissipate heat via a water-cooled condenser using deionized or distilled water circulation. Air-cooled models drive ambient air flow with fans, completing heat exchange through an air-cooled condenser for heat dissipation. II. Based on Test Specifications & Performance Requirements  Air-cooled: Ideal for small-scale tests (≤100L chamber), standard temperature range (-40℃~150℃), and moderate cooling speed needs (e.g., general electronic component testing). Water-cooled: Preferred for high-demand scenarios (cooling rate ≥50℃/min vs. air-cooled 30℃/min), such as chip wafers, new energy batteries, or aerospace materials testing, ensuring stability for long-duration (≥1000h) trials. III. Site Conditions Air-cooled: Suitable for limited space or mobile use—no extra piping required, just power supply and good ventilation (air-conditioned environment recommended). Water-cooled: Requires dedicated space for cooling towers/pumps, accessible water supply/drainage (e.g., industrial workshops or fixed labs); avoid small/non-drainable areas. IV. Cost & Maintenance  Air-cooled: Lower initial investment and maintenance cost—only need to clean radiators and check fans; no water leakage risk.  Water-cooled: Higher upfront cost (including supporting equipment) and maintenance fee (water treatment/piping checks); cost-effective for long-term high-precision testing. V. Noise Requirements Air-cooled: Acceptable for industrial workshops (noise ≥75dB). Water-cooled: Suitable for quiet environments (e.g., precision labs) with noise ≤60dB. VI. Core Selection Recommendations Water-cooled: Industrial scenarios with high power, continuous operation, high temperatures, or strict temperature control accuracy (stable water supply required). Air-cooled: General laboratories with limited space, intermittent use, no water supply, and demand for low cost and convenience.
