2、 Selection process and core requirements

（1） Comparison of Technical Parameters

Zhenyuan Tiancheng Technology has conducted a comprehensive evaluation of equipment from multiple suppliers, with a focus on the following key indicators:

Temperature range: It needs to cover -40 ℃ to+150 ℃ to simulate the performance changes of electronic materials under low-temperature storage and high-temperature aging scenarios.

Humidity control accuracy: The humidity fluctuation is required to be ≤ ± 2% RH to ensure the reproducibility of test data.

Inner box material: 304 stainless steel material is preferred to resist chemical corrosion and extend equipment life.

Refrigeration system: International compressors are required to ensure low-temperature stability and energy efficiency ratio.

The AP-HX-408C model of Aipei Technology stands out with the following advantages:

Temperature range: -40 ℃ to+150 ℃, meeting the requirements of full temperature range testing.

Humidity control: Adopting evaporator coil dew point temperature laminar contact dehumidification technology, the humidity uniformity reaches ± 2.0% RH.

Core components: Equipped with French Taikang fully enclosed compressor and Japanese Hitachi spare compressor, ensuring low-temperature refrigeration efficiency and equipment redundancy.

Inner box design: 600 × 850 × 800mm capacity with 304 stainless steel material, balancing large capacity testing and corrosion resistance.

（2） Industry case verification

Zhenyuan Tiancheng Technology found through case studies that Aipei Technology equipment has been successfully applied to multiple enterprises:

Suzhou Meigaochen Electronic Technology Co., Ltd.: Procurement of high and low temperature test chambers for reliability testing of semiconductor discrete devices, verifying the stability of equipment at temperatures ranging from -70 ℃ to+180 ℃.

Edico Le (Shanghai) High tech Materials Co., Ltd. has introduced a 225 liter constant temperature and humidity chamber to accelerate the research and development of new materials. The equipment has a zero failure rate within six months of operation, significantly improving research and development efficiency.

Shenzhen Yuanheng Optoelectronics Co., Ltd.: Using a UV accelerated aging test chamber to simulate outdoor environments, the error rate of LED product life prediction has been reduced to within 3%.

These cases demonstrate the mature application capabilities of Aipei Technology equipment in the fields of electronic materials, semiconductors, optoelectronics, etc., providing strong technical endorsement for Zhenyuan Tiancheng Technology.

3、 Equipment performance and technological innovation

AP-HX-408C is equipped with a 7-inch touch programmable controller (AP-900 intelligent type), supporting 120 sets of programs and 100 complex test designs per set, which can achieve:

Cycle testing: Set a composite testing process of high temperature and high humidity → low temperature and low humidity → alternating temperature and humidity.

Data traceability: Real time transmission of test data through RS232/RS485 interface, supporting USB export of historical records and curve graphs.

Remote monitoring: Optional LAN module for PC remote control, reducing manual intervention.

（2） Energy saving and stability design

Independent dual system: The heating and cooling systems are isolated to avoid thermal interference, reducing energy consumption by 15% compared to traditional equipment.

Refrigerant optimization: Adopting DuPont R404A/R23 environmentally friendly refrigerant from the United States, combined with an internal spiral copper tube design, to improve heat transfer efficiency by 20%.

Safety protection: Equipped with six safety mechanisms such as compressor high voltage protection, over temperature alarm, and leakage protection, to ensure stable operation of the equipment 24 hours a day.

4、 Delivery and after-sales service

（1） Fast delivery capability

Aipei Technology relies on the flexible manufacturing capabilities of its production base in Dongguan, Guangdong, and completes equipment production and debugging within 15 working days after the contract is signed, shortening the industry average delivery cycle by 40%. After the equipment arrives, a professional team will complete the installation and training within 24 hours to ensure that the R&D team of Zhenyuan Tiancheng Technology is immediately put into use.

（2） Full lifecycle services

Warranty commitment: We provide a 365 day warranty for the entire machine, and the warranty period for core components such as compressors and controllers is extended to 2 years.

Response mechanism: Set up 12 after-sales service outlets nationwide, promising to respond within 4 hours and arrive on-site within 24 hours.

Technical upgrade: Regularly push software update packages to support device function expansion and synchronization with industry standards.

5、 Application effectiveness and industry impact

（1） Improvement of R&D efficiency

After the equipment was put into use, Zhenyuan Tiancheng Technology achieved the following breakthroughs:

Shortened testing cycle: The time for a single temperature and humidity alternating test has been reduced from 72 hours to 48 hours, resulting in an overall 30% reduction in the research and development cycle.

Improved data accuracy: The humidity control accuracy has been increased from ± 5% RH to ± 2% RH, and the test data has been directly certified by ISO 17025 laboratory.

Cost optimization: Equipment energy consumption is reduced by 18% compared to imported brands, saving over 100000 yuan in electricity bills annually.

（2） Enhanced market competitiveness

With the support of Aipei Technology equipment, Zhenyuan Tiancheng Technology has successfully developed electronic packaging materials with stronger weather resistance. The products have passed international certifications such as UL and T ü V, and the export volume has increased by 65% year-on-year, with customers including top companies such as Huawei and BYD.

6、 Industry Insights

This case provides the following reference for equipment selection in manufacturing enterprises:

Technical orientation: Prioritize the selection of equipment with internationalized core components to ensure performance stability and technological foresight.

Service Loop: Focus on the supplier's delivery capability, after-sales response speed, and localized service network.

Cost optimization: comprehensively evaluate the full lifecycle cost through indicators such as equipment energy efficiency ratio and failure rate, rather than simply comparing purchase prices.
