Chilled Water Loops

CT + MRI + linac all require chilled-water supply for gradient / klystron / generator cooling.

Typical specs

• Supply temp: 6–15°C depending on modality
• Flow: 20–50 gpm depending on equipment
• Delta-T across equipment: ~5°C typical

Failure modes

• Chiller capacity undersized → scan time thermal limits hit
• Flow alarm → scanner stops (correctly)
• Water quality — particulates clog heat exchangers

Closed-loop deionized water preferred; chemical treatment required.
