Cooling Water AQ652 & AQ655
The AQ655 is a cost effective modular system that keeps the
level of nitrite based treatment within the desired parameters.
The system consists of a control module, which contains all the
sensor electronics, dosing control and the data communication
hardware and software. The dosing pump complete with suction
assembly and low level alarm are also mounted on the frame which
also allows space for two chemical treatment containers.
Installation is simple and can easily be carried out by ship?s
staff. The dosing units are placed close to the most convenient
point in each cooling water circuit to be treated, with only one
chemical injection line and one measurement point to be
installed
The control unit displays current reading.
Optionally, a data communication unit can be supplied for use
with any suitable existing PC to provide continuous display of
readings whilst pre-formatted management reports give a summary
of average readings for any period requested.
When possible, AQ652 systems with 2 pumps and dual controller on
one frame, can be implemented to save space.
Both AQ655 and AQ652 systems can be linked to other Aquanet
systems.

CONTROL MODULE
The module comprises 2 cards.
One card contains a microprocessor, analogue to digital
converter, non-volatile memory local LCD display and
communications interface.
The microprocessor card is connected via a ribbon cable
to a second card containing power supplies, isolation
amplifiers and alarm relays, this function of this card
is to power the remotely located probes and amplifiers.
All calibration values system timings and other
constants are retained in the non volatile memory.

Probes
The probe comprises a stainless steel sensor housed in
Peek body and screwed into a bronze shaft. The probe
includes a temperature compensation element. The entire
assembly fits into a retractable probe housing allowing
servicing and cleaning of the probe without closing down
the line. These probes are designed to operate from 20?C
to 150?C at 10 bar pressure.
