85°C 85%RH Constant Climate Chamber

Name: 85°C 85%RH Constant Climate Chamber
Brand: Xi'an LIB Environmental Simulation Industry

Reliability Testing for PV Modules | Compliant with IEC 61215 & IEC 61730 | Damp Heat Test

In the solar industry, long-term durability is non-negotiable. The 85°C 85%RH constant climate chamber is engineered specifically for the Damp Heat (DH) Test(high-temperature and high-humidity environment), simulating extreme tropical environments to evaluate a PV module's resistance to delamination, moisture ingress, thermal stress and material aging during long-term use.

Designed for continuous operation of 1000 to 2000 hours, our chambers provide the rock-solid stability required by global certification bodies.

Features and Benefits of 85°C 85%RH Constant Climate Chamber

1. Extreme Stability for Long-Term Tests:

Precisely maintains 85°C and 85% RH with minimal fluctuation. Our PID control logic ensures that environmental parameters remain constant over months of uninterrupted testing.

2. Optimized for Large-Scale PV Panels:

The spacious interior is designed to house standard 1m x 2m solar modules. The adjustable SUS304 stainless steel racks allow for vertical placement, maximizing airflow and testing efficiency.

3. Anti-Corrosion & Anti-Condensation:

The interior is constructed from high-grade laser-welded stainless steel to resist long-term humidity. A specialized air circulation system prevents condensation droplets from falling onto the cells, ensuring test integrity.

4. Intelligent Control & Data Logging:

Features a multi-language color touchscreen controller. Program complex cycles and export critical test data via USB or Ethernet for full traceability—essential for R&D and third-party labs.
