Ventilated Aging Test Chamber

The DHT® Ventilated Aging Test Chamber is purpose-built to replicate the environmental stress conditions that products may experience over extended periods of use. By precisely regulating temperature, humidity, and airflow, this accelerated aging test system enables efficient evaluation of a product’s durability, aging behavior, and long-term performance stability.

Through controlled environmental aging simulation, the chamber speeds up material degradation and performance shifts, offering critical insights into product lifecycle characteristics. It is especially effective for ventilated heat aging tests, where continuous airflow is essential to simulate real-world thermal exposure.

This advanced test chamber is widely applied in electronics, electrical engineering, automotive components, and materials science, serving as a key tool for reliability testing under ventilated thermal conditions. Whether assessing insulation stability, mechanical integrity, or material fatigue, the DHT® chamber delivers consistent, repeatable results in demanding R&D and quality assurance environments.

Benefits

High-Quality Chamber Construction: The inner chamber is crafted from imported high-grade stainless steel (SUS304) mirror panels or 304B argon arc welded materials, while the outer casing is made from A3 steel plates with a spray coating, enhancing both the aesthetic appeal and cleanliness of the unit.

Intelligent Temperature Control System: Equipped with a microcomputer-based intelligent program controller featuring temperature control protection and a timing function, ensuring precise and reliable temperature regulation.

Uniform Temperature Distribution: The hot air circulation system comprises a fan capable of continuous operation at high temperatures and a specialized air duct, ensuring even temperature distribution within the chamber.

Safety Protection Features: Includes an independent over-temperature alarm system that automatically interrupts heating when the set temperature limit is exceeded, ensuring safe operation during experiments.

Efficient Ventilation Function: Ventilation time and frequency are adjustable, ensuring that atmospheric changes during testing meet the required specifications.

Convenient Testing Interface: The left side of the chamber is equipped with a 50mm diameter test hole, allowing for the connection of external test power lines or signal cables.
