General Description
Do not install or use this equipment in any manner other than that which is specified in this
manual, otherwise the protection provided by this equipment could be impaired .
The Sentry® DCCP Reboiler Degassed Cation Conductivity Panel is designed to optimize
the analytical results for degassed cation conductivity of high purity water. Any other
use, or use not mentioned here, that is incompatible with the technical specifications is
deemed inappropriate. The operator is solely responsible for any damage arising from
such use.
Other prerequisites for appropriate use include:
ƒ Observing the instructions, notes and requirements set out in this or updated
instruction manuals.
ƒ Observing all local safety regulations.
ƒ Observing all warnings and cautions in the documentation regarding all products
used in this system.
ƒ Observing the prescribed environmental and operational conditions.
ƒ Observing chemical compatibility with all wetted materials.
The Sentry DCCP Reboiler is available in various configurations with and without
conductivity cells and cation exchange column depending on each customer's individual
requirements. Panels without the conductivity cells before the reboiler and without the
exchange column are designed to be used in conjunction with an analysis panel which
contains these components.
Regenerative Cooling Option
The Sentry DCCP reboiler has the option for designated cooling water or regenerative
cooling. With the regenerative cooling option, cooling water is not required. Instead, the
sample flow path is altered so that the sample cools itself while running through the DCCP
panel. The overall dimensions of the two versions are the same.
For best performance when using regenerative cooling, sample temperatures should not
exceed 113°F (45°C) or the analyzer sensor temperature limit designated in the analyzer
manual). Sample flow should not exceed 150 cc/min when using regenerative cooling.
 NOTE
Sentry Equipment recommends using a temperature-controlled cooling water source for sample
cooling, controlled to 77 F (25 C) for best CO2 removal performance . This recommendation is
consistent with applicable EPRI, ASME and ASTM guidance . If regenerative cooling is selected
the user should understand the DCC analyzer temperature compensation performance and
limits .
Please refer to the P&ID Layouts of both designs below.
