The long cooperation between LIB and NUS began in 2019, mainly to solve the salt fog test of photovoltaic panels in the photovoltaic laboratory. In August 2023, LIB provides a walk-in corrosion chamber for large PV Modules testing.
Communicate the prerequisite testing requirements and determine the appropriate chamber, production, inspection and delivery. After the walk-in salt fog chamber were delivered to NUS, our engineers came to perform installation and commissioning, and the progress went as scheduled.
We hope to provide more support to NUS laboratory to achieve better scientific research.
1. Large-Capacity Testing for Full PV Modules
The spacious walk-in design allows simultaneous testing of multiple large photovoltaic panels, improving laboratory efficiency and supporting comparative research projects.
2. Stable and Uniform Salt Fog Environment
Optimized spray tower design and high-quality quartz nozzles ensure consistent fog distribution throughout the chamber, minimizing test deviation and ensuring credible research data.
3. Intelligent Control & Data Traceability
The multilingual touchscreen interface supports multi-step programmable testing. Real-time data logging enables researchers to export temperature, humidity, and spray records for analysis and reporting.
4. Robust Safety & Continuous Operation
Automatic water replenishment, dry-burn protection, and alarm systems ensure uninterrupted long-duration testing—critical for photovoltaic corrosion resistance validation.
5. Long-Term Service Support
LIB provides comprehensive technical support, remote troubleshooting, and on-site service when required, ensuring stable operation throughout the equipment lifecycle.

The walk-in salt fog corrosion chamber plays a critical role in photovoltaic reliability research. For coastal and high-humidity regions, PV modules are constantly exposed to saline air, which can accelerate corrosion of frames, junction boxes, connectors, and mounting systems.
By simulating long-term salt fog exposure under controlled laboratory conditions, researchers at the National University of Singapore can evaluate material durability, optimize coating technologies, and improve module structural design. This enables more accurate lifespan prediction and enhances product reliability before market deployment.
From requirement analysis to final delivery, LIB followed a structured project workflow:
Technical consultation and chamber customization
Manufacturing and in-factory inspection
Safe overseas transportation
On-site installation and commissioning
Operator training and performance verification
After installation, comprehensive system calibration and salt deposition validation were conducted to ensure compliance with international standards. The chamber successfully passed acceptance testing and was officially put into laboratory operation as scheduled.
This project reflects more than equipment supply—it represents technical collaboration. By providing stable and repeatable corrosion simulation conditions, LIB supports NUS researchers in conducting advanced studies on photovoltaic durability, coating technologies, and environmental stress performance.
Reliable environmental testing equipment forms the foundation of high-quality scientific research. With accurate corrosion simulation capability, researchers can confidently publish data, validate product improvements, and accelerate innovation in renewable energy technologies.
LIB remains committed to supporting global research institutions and industrial laboratories with customized environmental testing solutions. The successful implementation of the walk-in salt fog corrosion chamber at NUS further demonstrates LIB’s capability in delivering large-scale, precision-engineered corrosion testing systems.
LIB Industry look forward to deepening cooperation and contributing to future breakthroughs in photovoltaic performance and long-term durability research.
