Condenser approach drifting up — likely tube fouling

The gap between condenser leaving water temp and refrigerant condensing temp has grown over time when normalized by load.

What does PLANT-03 mean?

The gap between condenser leaving water temp and refrigerant condensing temp has grown over time when normalized by load.

Why does it matter?

Every 1°F of extra approach typically costs 1–2% in chiller efficiency. Compound across a season and the bill is real. Tube fouling is the most common cause; eddy-current testing is the gold-standard inspection.

What should you do?

Schedule a tube cleaning or brush. Check condenser-water chemistry. Verify CW flow is at design.
