The Watermaid
Salt chlorinator has been designed with the
home swimming pool in mind. The output power
supply is capable of 30amp output at 8.6VDC The
cell wiring and cables and connections are
designed and rated at 30 amps DC
Given these restraints and knowing that 1 amp of
current with these cells produces about 1 gram
per hour it is obvious that the maximum
output from a Watermaid Chlorinator will be
about 30 grams of 100% available chlorine per
hour.
Commercial operations base their chlorine use on
about 1 Kg of chlorine per 20 bather
hours.
Clearly then the Watermaid is not designed for
commercial use unless more than one Watermaid
unit is installed, as is the case with many
commercial pools.
For large hotels where the bather load is
within the parameters of the units ability, one
will and does find many units in use in such
areas.
Our units will run on any salt level from
4000ppm to sea water which is 35,000 ppm
The cost of making chlorine is about 6.28
kilowatts per Kg of 100% chlorine equivalent.
That generally works out to be 1/6 of the cost
of buying chlorine powder in Australia.
In commercial situations the cells have a
life of 30 months when run 24 hours a day. Cells
will make some 25 grams per hour.
The major disadvantage is chlorine on demand.
The units make 25-30 grams per hour and if you
have a herd of elephants in the pool and want
more chlorine to cope then you must manually add
it for that period. The usual premise is that
for every 20 bathers you normally add 1 Kg of
chlorine per 24 hours.
Another minor disadvantage is water loss.
In horse pools where chlorinators are
used, 40 horses will drag out up to a 2000 -
4000 litres of water per day (together with the
salt). A 25 Kg bag of salt must be added to
replace it. Normally salt and water are not lost
as salt is converted to the hypochlorite and
then to salt again.
Some public pools have similar water losses.
Note: The
Watermaid Unit is capable of making up to
- 720 Grams of 100% Available Chlorine per Day
- 5.040 Kilograms of Available Chlorine per Week |
