Climatic Chambers for Solar Light Tests

Name: Climatic Chambers for Solar Light Tests
Brand: Xi'an LIB Environmental Simulation Industry

The climatic chambers for solar light tests with Optional Low-Temperature Capability from LIB industry is engineered for precise solar simulation and robust environmental control. Equipped with full-spectrum xenon lamps delivering high-intensity, uniform irradiance ±5 %, it replicates natural sunlight for accelerated aging and durability testing of coatings, polymers, automotive components, and solar materials.

The climate solar light chamber also supports sub-zero temperatures from –40 °C to +100 °C with a precision of ±0.5 °C, enabling low-temperature stress testing as an added feature. Humidity control from 20% to 95% RH further expands its versatility, allowing realistic environmental simulations under UV exposure.The workroom volumes can be customized based on your testing requirements.

Model Options For You: XL-S-500,XL-S-750

Applicable Standards: IEC 60068-2-5, IEC 60068-2-27,ASTM G26,ISO 105, ISO 4892-2, ASTM G155, ASTM G151, ASTM G155,ISO 105-B02 (EN) (DIN), ISO 105-B04 (EN) (DIN).

Why Perform Low-Temperature Xenon Testing?

Unlike standard xenon arc chambers limited to ambient to 100 °C, low-temperature xenon testing reveals how materials respond to extreme cold while under solar radiation. Many polymers, coatings, and adhesives become brittle below freezing, and when combined with UV stress, they may crack, peel, or lose adhesion—behaviors invisible in conventional tests.

This climate solar light chamber is essential for:

Solar panels and photovoltaic coatings, which face sub-zero winters and high solar irradiation.
Automotive exterior coatings, vulnerable to frost and UV-induced cracking.
Outdoor polymers and composites, where low-temperature embrittlement plus UV aging can lead to early failure.

By simulating subzero winter conditions under intense xenon light, manufacturers gain predictive data on material durability, helping reduce field failures, extend product lifespan, and meet stricter quality standards.

Key Advantages of Climatic Chambers for Solar Light Tests

1. High-Precision Solar Simulation

Full-spectrum xenon lamps deliver uniform irradiance ±5 % with intensity up to 150 W/m², accurately replicating sunlight for accelerated aging. Lamp output remains stable over long-duration tests for reproducible and precise results.

2. Broad Environmental Range

Temperature range of –40 °C to +100 °C with ±0.5 °C stability and 20–98 % RH humidity control allows combined UV and environmental stress testing. Low-temperature capability enhances testing scenarios while preserving xenon lamp performance.

3. Long-Life Xenon Lamps & Energy Efficiency

Optimized lamp cooling and dual-stage refrigeration ensure continuous operation, extending xenon lamp life to ≥1,600 h. Energy consumption is reduced by up to 15 %, while maintaining stable UV intensity and climate solar light chamber conditions throughout extended cycles.

4. Intelligent Control & Safety

Programmable PLC touchscreen controller supports multi-step cycles with adjustable UV intensity, temperature ramps, humidity variation, and water spray. Safety features include overheat, overcurrent, lamp cooling monitoring, and anti-freeze protection for reliable operation of both samples and equipment.

5. Condensation / Nighttime Humidity Simulation

The climate solar light chamber can simulate nighttime condensation and high-humidity environments as part of cyclic UV testing. Humidity ramps up to 95 % RH at low temperatures, reproducing morning dew or cold condensation scenarios.
