The article offers the author's encounter of repairing a chiller. He notes that the capacity of a large calcium-chloride brine chiller has decreased steadily over time. He mentions that the chiller heat exchanger was large 400-ton-refrigeration low temperature of -20 degrees Fahrenheit with flooded-ammonia evaporator. Cause of the damage includes internal tube fouling, low refrigerant level, and insulation degradation. His solution was draining of oil from the brine chiller's bottom.
