• Within the CENTRA – R200 US connections are
available to link to externally positioned cylinders
containing water purification media, to remove impurities
and maintain water purity around the system. The media
in the cylinders can be selected to meet specific
requirements.
WARNING: Any cylinders or additional equipment
installed (filters etc.) including ring-main
pipework, must be rated to the operating
pressure of the CENTRA system (6 bar
maximum).
• CENTRA - R200 US units include a UV chamber (UV1)
where purified water is exposed to intense UV radiation
to provide continuous bacterial control and to promote
the cleavage of organic molecules.
• Final filtering is provided by an absolute 0.2µm bacterial
and particulate filter. The difference in delta P between
PG1 and PG3 can be used to monitor the condition of the
filter.
• Finally the purified water passes through a:
• Temperature sensor (TS2), which provides accurate
temperature measurement.
• Water quality sensor (QS2), which measures the
resistivity of the water.
• Flow sensor (FS1) which electronically measures flow
around the system.
• Air is drawn into the reservoir when water level falls. To
maintain water purity, it is necessary to filter the air.
Water quality is maintained within the recirculation
system using a composite vent filter, which removes air-
borne contaminants such as volatile organic compounds
and carbon dioxide as well as air-borne particles and
bacteria.
• The CENTRA - S200/R200 US includes the ability to
drain the reservoir completely via V4 and sanitize the
installation semi-automatically via V8 to ensure that
bacterial levels within the installation are controlled.
