On June 9, 2025, a delegation from a leading Polish producer visited LIB's manufacturing facility. They confirmed their purchase of two key products: a chamber that simulates temperature and humidity for PV modules, and another for UV preconditioning tests. This collaboration underscores the Polish manufacturer's dedication to the most rigorous quality assurance processes and highlights LIB's reputation as a premier provider of advanced environmental testing solutions.
【LIB Launches Advanced PV Module Durability and UV Preconditioning Test Chambers】
As for LIB's Temperature and Humidity Chamber for PV Modules, this Chamber offers three rigorous, standards‑compliant test regimes to validate long‑term module performance:
Damp Heat Mode: It maintains conditions of 85 ℃ and 85% RH for over 1,000 hours in line with IEC 61215, IEC 61646, and UL 1703 standards, with precise control at ±2 ℃ and ±5% RH. This setup simulates tropical humidity to expose corrosion risks and early signs of material breakdown.
Humidity‑Freeze Cycling: Conducts ten cycles of 20 hours at 85 °C/85 % RH, a rapid cooldown to –40 °C for 30 minutes, and stabilization at 25 °C/85 % RH. This sequence rigorously tests seal integrity, moisture ingress resistance, and mechanical resilience under sudden thermal shocks.
Thermal Cycling: It can run up to 200 temperature cycles ranging from -40 ℃ to 85 ℃. Each extreme is held for 10 minutes, and a full cycle finishes in under six hours to mimic day-night and seasonal temperature changes.
Equipped with high‑accuracy PT‑100 Class A sensors, PID control, chromium‑nickel heating elements, and a TECUMSEH compressor delivering 100 °C/hour cooling with eco‑friendly refrigerants, the chamber balances precision, speed, and sustainability.
Temperature and Humidity Chamber for PV Modules
Complementing this, LIB's UV Preconditioning Test Chamber uses fluorescent UV lamps to simulate natural sunlight.
Operating at 60 °C ± 5 °C under programmable irradiance cycles, it combines UV exposure, heat, humidity, and simulated rain to accelerate photo‑oxidative damage.
This accelerated testing helps manufacturers evaluate the UV resistance of materials and coatings, speeding up development and ensuring long-term outdoor durability.
