PG25 High Velocity Erosion Test - Evaluating Coolant Performance at Elevated Flow Rates

Learn about erosion testing results for high-velocity coolant systems in data center thermal management through this 24-minute conference presentation. Explore how ASHRAE's traditional 1.5 m/s velocity limit constrains modern thermal system design as heat loads increase, and discover why raising fluid velocity offers a more energy-efficient solution than lowering coolant temperatures. Examine the collaborative study between the Open Compute Project and bp-Castrol that tests Castrol PG25 coolant at elevated velocities across copper, stainless steel, and EPDM pipes. Review early findings from copper pipe testing at 6 m/s velocity—the most erosion-prone scenario—and understand the implications for designing thermal systems that meet higher thermal design power (TDP) demands while maintaining energy efficiency.
