    Even when your chiller is inspected and maintained regularly, its performance can degrade or deteriorate over time. Pumps can fail, process lines can clog, refrigerant can leak, and any number of problems associated with component aging or changing environmental conditions can occur (table 1).

    As process plants become larger and are operated closer to safety limits, a systematic approach to safety becomes a necessity.

    Variable-flow chilled water plants are designed to main-tain a relatively constant delta-T, the difference between return and supply chilled water temperature. But in almost every real chiller plant, delta-T falls well short of design levels.
