DHT® Temperature and Humidity Test Chamber: Ensuring Quality in the Compressor Manufacturing Industry

Written by Shirley
Product Manager, Doaho Test (DHT®）

The company is a leading global compressor manufacturer, serving over 50 countries. With a relentless focus on a “zero-defect” standard, it has established a strong presence in the industrial compressor field. Its products are widely used in high-end applications such as rail transportation, data centers, and new energy, where extreme performance and long-term operational stability of core components are critical.

To meet these rigorous demands, the company integrates advanced environmental testing systems into its quality control process, including thermal shock test chambers for rapid temperature variation testing and benchtop environmental chambers for precise, small-scale reliability assessments. In addition, drive-in chambers are utilized to evaluate large assemblies under dynamic environmental conditions, ensuring that every unit meets the highest performance and durability standards. The company demands both precision and efficiency in its manufacturing processes.

Client’s Pain Points and Requirements

Compressors operate under extreme temperature and humidity conditions ranging from -30°C to +50°C, requiring 2,000 hours of continuous durability testing. However, the client’s previous test chambers suffered from significant temperature drift (±1.5°C), high failure rates, and large fluctuations in product quality control. After a comprehensive evaluation, the DHT® Temperature and Humidity Test Chamber emerged as the ideal solution due to its superior temperature control accuracy, intelligent system, and long-term reliability, making it the new test chamber supplier for the company.

Core Advantages of the DHT® Test Chamber

1.Precise Temperature Control: Ultra-Stable within ±0.5°C

The DHT® Temperature and Humidity Test Chamber utilizes German-designed CHDHT Cold and Dry-Wet Partition Intelligent Control Technology, ensuring temperature fluctuations remain within ≤±0.5°C even during continuous low-temperature operation at -40°C. The humidity deviation is kept within ≤±2% RH. In real-world testing, the company completed 2,050 hours of uninterrupted testing using the DHT® test chamber, with the temperature curve standard deviation reduced by 67% compared to the old equipment.

2.Smart Adaptability: From “Usable” to “User-Friendly”

The advanced remote management system allows for precise control from a distance, enhancing operational safety. The automated testing process reduces manual intervention and automatically generates reports based on test data, resulting in a 35% reduction in labor costs.

3.High-Frequency Use: Long-Term Operation with Robust Durability

The DHT® test chamber is designed for long-term, continuous operation. With an integrated preventive maintenance system, it eliminates the need for additional maintenance costs, making it ideal for high-frequency usage scenarios and helping the client achieve a 35% reduction in total lifecycle costs.
