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.

• Operation Notes for Rapid Temperature Change Test Chambers: Don't Overlook These Key Points

  Dec 02, 2025

      As a core device for environmental reliability testing, the rapid temperature change test chamber is widely used in electronics, automotive, and other industries due to its ability to achieve drastic temperature variations. Its high/low temperature performance and rapid temperature change capability directly affect test data accuracy, operational safety, and equipment service life. Below are the core operational precautions: I. Pre-Startup: Conduct Basic Inspections Comprehensive pre-startup checks are critical for preventing malfunctions, focusing on "medium, status, and connections": Medium & Pipeline Inspection: Verify that the cooling system's liquid level and pressure meet standards, with no pipeline leakage or blockage. Check the refrigerant system pressure to avoid cooling failure or compressor damage due to insufficient medium. Equipment Status Confirmation: Ensure the chamber door seal is intact (poor sealing reduces temperature change rate and increases energy consumption). Keep the chamber interior clean and free of debris, and ensure sensor surfaces are free of oil and dust to avoid temperature measurement interference. Electrical Connection Check: Confirm power and control cables are securely connected, and the grounding resistance complies with specifications (≤4Ω) to prevent electric leakage or electromagnetic interference. II. Sample Placement: Prioritize Scientific Standards Proper sample placement ensures test authenticity, adhering to the principles of "no interference, no overrun, easy monitoring": Weight & Volume Control: Total sample weight must not exceed the rated load. Single sample volume ≤ 1/3 of the working chamber. Maintain a distance of ≥5cm from the chamber walls and sensors to avoid uneven local temperature caused by airflow blockage. Sample Compatibility: Never place flammable, explosive, corrosive, or toxic samples. For heat-generating samples, specify power in advance to ensure compatibility with the equipment's heat dissipation capacity and prevent overload. Fixing & Wiring Specifications: Secure samples with dedicated brackets to prevent displacement during temperature changes. Use high-temperature resistant insulated wires for energized tests to avoid short circuits and aging. III. Operation Process: Precise Monitoring & Adjustment Dynamic monitoring during operation guarantees test reliability, focusing on "parameters, status, and abnormalities": Parameter Setting & Verification: Set temperature range, change rate, and other parameters per standards and re-verify. Adjust only after the equipment stabilizes to avoid system fluctuations. Operation Status Monitoring: Real-time monitor temperature curves and indicator lights to ensure the deviation between actual and set temperatures ≤ ±1℃. Listen for abnormal noises from components like the compressor and shut down immediately if detected. Abnormal Handling: If the equipment triggers over-temperature, overload, or other protections, do not force reset. First troubleshoot the cause (e.g., abnormal sample heating, unstable voltage) before restarting. IV. Post-Test: Standardized Shutdown & Maintenance Proper post-test procedures extend equipment life, following three steps: "cooling, cleaning, and recording": Gradual Cooling to Prevent Damage: After testing, open the door only when the chamber temperature drops to room temperature (20-25℃) and the temperature difference with the outside ≤10℃, avoiding sample condensation or chamber wall damage. Cleaning & Maintenance: Wipe the chamber interior and door seal with a dry cloth. Use dedicated cleaners for leaked substances. Remove dust from the equipment exterior to ensure unobstructed heat dissipation. Data & Status Recording: Document test parameters, curves, and abnormalities. After turning off the power, cut off the cooling medium supply and organize wires and brackets. V. Long-Term Maintenance: Extend Equipment Lifespan Regular maintenance prolongs service life: Monthly: Check the door seal elasticity and replace if aged. Quarterly: Clean the condenser and evaporator. Annually: Arrange professional inspection and maintenance of the compressor and refrigeration system. The core of test chamber operation is "safety first, standardized operation, and precise monitoring." Strict adherence to the above precautions ensures safety, reliable test data, and extended equipment life, providing strong support for product reliability verification.

• 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.

• Industrial Precision Ovens: The Key to Precise Temperature Control

  Nov 21, 2025

  In modern industrial manufacturing, industrial precision ovens are key "temperature artisans". They are widely used in electronics, aerospace, automotive, medical and other fields, providing stable performance and reliable quality for products. Gaining an in-depth understanding of their principles not only clarifies the scientific logic of industrial production, but also helps practitioners use equipment efficiently to improve benefits. (I) Heating System: The Source of Heat The heating system is the "heat source core" of the oven. The thermostat controls the thyristor through signals to adjust the heater power and regulate heat output: full power is supplied when the temperature is much lower than the set value, power gradually decreases when approaching the set value, and output stops when the set value is reached. This is energy-efficient and achieves high temperature control precision. (II) Air Circulation System: The Messenger of Heat Transfer Composed of a blower motor, extended shaft and multi-wing fan blades, the air circulation system is critical for heat transfer. The motor drives the wind wheel to rotate and form air flow, which is evenly delivered to all areas of the oven through optimized air ducts, avoiding dead corners and temperature differences. Hot air fully contacts materials during circulation to achieve rapid and uniform heating, which is essential for high-precision processes such as electronic chips and optical lenses. (III) Electrical Control System: The Core of Precise Operation The electrical control system is the core control unit of the oven. The Q8 series electrical control system adopts full-touch operation with a control precision of 0.01 level and supports multiple sensor adaptations. It has 100 built-in processes (50 steps per group), including EVT, cold output and transmission output functions. The DO channel features safe isolation and arc suppression design, enabling convenient, accurate and reliable operation that adapts to diverse control scenarios. Future Outlook: Technological Innovation Leads Development In the future, industrial precision ovens will focus on three major innovation directions: intelligence, energy conservation and environmental protection, and special process adaptation, continuously innovating to shape a new industrial future.
