Sanwood Technology Temperature Humidity Test Chamber: 168-hour Stable Operation Without Frost Under Low Humidity

In the reliability testing of high-end manufacturing products such as semiconductors, new energy products, auto parts and precision electronic components, stable temperature and humidity control as well as reliable equipment operation serve as the core premise for accurate and valid test data. In the field of environmental reliability testing, long-term stable control of low-humidity working conditions has always been a technical difficulty in the test chamber industry.

Targeting common industry pain points, Sanwood Technology Temperature Humidity Test Chamber has passed rigorous extreme working condition tests, achieving 168 hours of uninterrupted continuous operation at 25℃ and 5%RH ultra-low humidity environment.

Drawbacks of Traditional Ultra-low Humidity Long-term Testing

Traditional equipment has prominent defects in ultra-low humidity long-term testing scenarios, including poor humidity control accuracy, easy humidity rebound and frequent frost formation on compressors during long-term operation. Additional auxiliary equipment such as dehumidifiers and dryers are mandatory for normal operation. This not only increases corporate costs for procurement, energy consumption and maintenance and occupies laboratory space, but also frequently causes test suspension, data distortion and repeated testing, seriously hindering product R&D and quality inspection efficiency.

Technical Breakthroughs of Sanwood Technology

Based on in-depth insights into industry testing pain points and years of R&D experience in environmental test equipment, Sanwood Technology has completed technical iteration and actual measurement verification of the Temperature Humidity Test Chamber according to customized customer requirements. The detailed technical parameters are as follows:

Temperature Range: -70℃ ~ +150℃

Humidity Range: 5%RH ~ 98%RH (Applicable temperature range: +20℃ ~ +85℃; 5%RH corresponding at 25℃)

Heating Rate: 3℃/min from -70℃ to +150℃

Cooling Rate: 2℃/min from +150℃ to -70℃

The entire unit requires no additional dehumidifiers, dryers or other auxiliary equipment. Accurate constant temperature and humidity control is fully realized via self-developed optimized compressor systems. The compressor operates stably with zero frost formation and zero faults throughout the operation process, breaking the technical bottlenecks of traditional equipment, which relies on auxiliary devices, suffers from easy frost accumulation and unstable humidity control.

Practical Engineering Value for Customers

Reduced System Complexity: No need for additional procurement of dehumidifiers, dryers or adsorption modules, eliminating potential failure points of auxiliary equipment.

Improved Test Continuity: 168-hour continuous operation without defrosting interruption, compatible with long-cycle reliability tests and preventing invalid test data caused by suspension. The equipment supports longer continuous operation durations.

Lower Operation and Maintenance Costs: No regular replacement of dryers or maintenance of external dehumidification units is required.

Higher Data Reproducibility: Eliminates temperature and humidity fluctuations caused by defrosting, ensuring more stable and comparable test results.
