The Damp Heat Test Chamber is designed to evaluate the long-term reliability and environmental durability of photovoltaic (PV) modules under high temperature and humidity conditions.
This chamber simulates tropical or coastal environments to test material degradation, corrosion resistance, and adhesion failure. It is essential for IEC and UL standard certifications.

Walk-in High Temperature & Humidity Test Chamber (DH)

Model: HY-BRS-DH Series

Excellent temperature uniformity and high test accuracy
Adjustable airflow volume, velocity, and direction via air deflectors to ensure smooth air circulation.
Optional surface temperature control function to meet strict ramp rate requirements.
Automatic load calculation for optimized system output regulation.
Fully welded chamber structure prevents moisture leakage and enhances pressure resistance.
Integrated universal sample fixture with insulation and thermal isolation.
