Installation
and operation instructions for evaporation cooling tower.
Installation: The installation of AQUA CORRECT system
is performed into the water supply pipe. The AQUA
CORRECT capacity type shall be selected for full conditioning
of the maximum water flow. There is no demand to flow direction,
horizontal or vertical installation. The draining outlet pipe
from the cooling tower must be connected to the lowest point
of the water tank and the size of the pipe must secure effective
removal of impurities (min. 1 1/4" pipe) in free fall toward
ground.
The draining shall be valve controlled by the installation of
a conductivity sensor connected to an automatic
processor (range: 0 to approx. 2000 m Siemens/cm) with upper
and lower output limits.
Operation
instructions: The draining
of concentrated mineral salts and impurities form a technical
part of the treatment procedure and performance guarantee. It
is dependent on the amount of evaporated water and the water
hardness. The conductivity in the water must not normally exceed
the value of 1200 m Siemens/cm (approx. 37 0dH = 660 PPM).
In accordance with the American CTI-standard (USA) and the equivalent
German VDI-DIN 1947-
recommendations:- In addition to evaporated water (Wwo - a constant),
a sufficient draining of the concentrated minerals (Wwa) is done
and new conditioned water (Wwz) replaces the loss. The recommended
values are:
-Wwo: 0.15 x K (cooling area) x V (amount of water) /100 = m3/h
for open circuits.
-Wwo: 3.60 x Q (cooling effect kW) /2500 = m3/h for closed circuits.
-Wwa: = Wwo (max. standard value, but depending on the concentration
velocity)
-Wwz: Wwa+ Wwo = m3/h (generally + or - % local depending)
IMPORTANT!
The physical AQUA CORRECT conditioning of the water supply replaces
the use of all softening units and
previously chemical dosage. In case of chemical use for removal
of algae, the dosage can be reduced in
accordance with a10% reduced water surface tension. Any disposals
or corrosion reaction by using chemicals is the responsibility
of the supplier of the chemicals only. Remove all water and use
only AQUA CORRECT system conditioned water at first time start
up!
Static voltage tension potentials, for instance frictional electricity
by use of PVC tubes, may cause lime deposits in all systems and
are excluded from the treatment guarantee.
WORKING
CONDITIONS
During the dissolving of existing deposits it shall be expected
that loosened substances, which can not pass through nozzles
must be removed manually. Dissolved substances may increase the
pH values and form
impurities on the conductivity sensor electrodes. Regular maintenance
of the electrodes and the draining function is required according
to local conditions.
GUARANTEE
The function guarantee is related to above conditions being followed.
The AQUA CORRECT guarantee is valid for the described function
within a period of 6 months, provided payment is made for the
AQUA CORRECT system supplied. The material sustaining guarantee
is 5 years.
