•
The purified water is then passed through the UV (UV1)
chamber where it is exposed to intense UV radiation to
provide continuous bacterial control and to promote the
cleavage of organic molecules before passing through an
absolute 0.2µm bacterial and particulate filter. The
pressure drop across the filter can be monitored to
ensure optimum performance is maintained (PG1 and
PG2).
•
Finally the purified water passes through a:
•
Temperature sensor (TS2).
•
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 is used. To
maintain water purity it is necessary to filter the air. Air-
borne particles and bacteria are removed by an air-filter.
Alternatively an improved level of water purity can be
maintained within the recirculation system using a
composite vent filter, which also removes air-borne
contaminants such as volatile organic compounds and
carbon dioxide.
•
The
CENTRA – RDS/HFV/HFR 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 kept to a
minimum.
•
The temperature within the distribution system will rise
after long periods of recirculation. If the system is not
receiving cooler water through V2, V9 will automatically
open once a preset temperature limit is reached. This
reduces the water level in the reservoir until V2 opens
and cooler water enters the system.
•
V9 can be fitted as an optional extra.
