In January 2023, a customer consulted LIB industry for a comprehensive corrosion testing solution dedicated to server reliability evaluation. The test objects included servers with multiple form factors (1U, 2U, and 4U), all required to operate under powered-on conditions during testing.
To accurately simulate real operating environments, the customer required both:
Cyclic salt corrosion testing, and Mixed toxic gas corrosion testing,
with strict requirements on heat load management, gas compatibility, internal structure flexibility, and long-term operational stability.
Compared with conventional corrosion testing, this project presented several technical challenges:
High internal heat load (≈ 5000 W) generated by powered servers
Multiple server heights requiring flexible internal layout
Simultaneous operation of multiple 4U servers
Multi-gas corrosion testing with strict safety and concentration control
Long-duration testing with stable and repeatable conditions
LIB industry addressed these challenges through engineering-level customization, rather than standard equipment configuration.
During powered-on testing, uncontrolled heat accumulation can significantly affect salt corrosion results. To maintain stable environmental conditions, LIB industry redesigned the cooling structure of the SOM-036.
Titanium alloy refrigeration tubes installed on the sidewalls of the workroom
High corrosion resistance suitable for continuous salt spray exposure
Optimized airflow circulation to counteract thermal accumulation
Reliable temperature stability throughout the test cycle

This system provides uniform gas distribution, precise concentration control, and a safe testing environment for long-term corrosion evaluation.
To accommodate servers of different heights, LIB industry specially designed a detachable shelving system, featuring:
Adjustable installation height
High load-bearing performance
Easy disassembly and reconfiguration
Improved airflow and corrosion consistency
This modular design allows the same chamber to support future server models without structural modification.
