Why does crystallization occur?
The most common reason for crystallization is power failure. If a chiller is running at full load and
power is interrupted for a sufficient length of time, the concentrated solution in the high side of the
unit eventually cools down. Because no dilution cycle is performed, the solution concentration in
some areas of the unit is still high. If the temperature of this concentrated solution falls enough,
the solution reaches its crystallization point. Plant room temperature, insulation quality, and the
solution concentration all affect how long it takes before the unit crystallizes. For more information
on water quality control and crystallization, see
. The Duhring Diagram / PTX Chart
shows the specific temperatures and pressures of the crystallization area. See Figure 74 and Figure
