As liquid cooling becomes increasingly important for high-density data centers, manufacturers need to validate systems against real-world thermal and electrical conditions.

This case study explores how Apx Data Centre Solutions uses Avtron LC35 liquid-cooled load banks to test and refine its coolant distribution units (CDUs).

Using two 500kW LC35 units, Apx can generate controlled thermal loads of up to 1MW, replicate high-density rack behaviour and simulate rapid load changes and thermal transients. Integrated instrumentation captures temperature, flow, pressure and electrical load data, enabling precise and repeatable testing.

What you'll learn in this case study:

• How liquid-cooled load banks replicate high-density rack conditions
• How Apx tests CDU performance under realistic operating scenarios
• How precise load testing supports reliable liquid-cooling technology validation
