University HVAC systems underperform because each building added to a campus distribution loop introduces new pressure dynamics. Pressure-dependent terminal unit valves draw disproportionate flow at part load, collapsing delta T system-wide and stranding cooling capacity at the plant — even when individual buildings are calling for more.

University chilled water systems face a compounding problem that most commercial buildings don’t. Each building added to a campus distribution loop introduces new pressure dynamics. Older buildings with pressure-dependent valves draw disproportionate flow when loads are low, collapsing delta T system-wide and starving newer or more remote buildings of capacity.

Facilities teams respond by running additional chillers, adding pumping capacity, or planning plant expansion — all of which treat the symptom rather than the cause. The root cause is hydronic imbalance at the terminal unit level, and it worsens as campus load profiles shift across the academic year.

A pressure independent control valve eliminates this interaction. The DeltaPValve® maintains precise flow at each terminal unit regardless of what other buildings are drawing from the loop. Delta T stabilizes. Plant capacity returns. The chiller that was staging on a mild day stays off.
