Ultra
Violet Sterilising Systems
Our
UV systems are ideal for treating private water
supplies.
Ultra
Violet water filters are highly efficient at killing
bacteria, viruses and other micro organisms that
can be found in un-treated water.
The
way they work is by passing water through a chamber
which is flooded with Ultra Violet light.
The
UV light shines powerfully through water passing
along the unit, destroys the cell's DNA thereby
neutralising it.
Typical
Uses for UV systems
If
you have a private water supply ie get your water
supply from a well, borehole or river etc.
How
to get the right UV unit for your needs
The
main criteria you need to consider is what
size unit you need.
This
main factor this depends on is the flow
rate of your water.
You
may also need to consider what electrical power
you have available.
When
you have established these please refer to your
UV filters selection
table
Importance
of choosing a high quality UV unit
To
choose the best UV for your needs you also want
to make sure it is a high quality
and not low quality UV unit.
This
is because you want to make sure the UV you are
using is reliable.
If
the UV unit fails you might, at best, end up with
a bad stomach.
At
worst - for example if you ingest micro organisms
like cryptosporidium - you could have serious
health problems that last for several months.

below for More on High vs Low Quality
UV Water Filters
Other
essentials
Finally
all UV water filters should have a suitable
pre-filter to remove any
waterborne particles or debris.
These
will create a "shadow" behind which some
micro organisms, like bacteria, might be able to
hide. This prevents the UV light neutralising them.
Your
recommended pre-filter for each UV model depends
on your local water quality. We can advise you on
this.

More
about High vs Low Quality Ultra Violet Water Filters
As
stated above you need to buy a well made, high quality
unit and avoid low quality UV filters.
Some
of the differences are:
A
low quality unit has no inbuilt warning
system, and / or no lamp-life count
down indicator - which gives you a pre-warning
that the lamp needs replacing.
Our
units give you good warning with
a weekly alarm that gives you a regular reminder
for the last 4 weeks of the lamp's life. At the
end of the lamp's life your lamp still works but
it then starts to beep incessantly until you change
it.
Low
quality units do not do this. Instead they simply
stop working, leaving you with a sudden problem
of no safe, filtered water.
We
sell high quality R-Can, Sterilight and Trojan units
- famous, market leading brands.
How
can you tell good from bad?
Notice
that we say "low quality units". We don't
say "low priced" because often these low
quality cheap units - imported from China , India
or Eastern Europe- are more expensive than the better
ones.
As
a website and not a shop that needs to cover its
high costs of rent, utilities and rates, we can
offer our high quality North American made, famous
brand UV's at a reasonable price.
More
benefits of good quality UV systems
Our
high quality branded UV systems have high frequency
electronic controllers to start up and run the lamp
/ bulb.
Lower
quality UV's tend to us old style choke and starter
circuits to run the lamps
The
former are much more efficient
thereby reducing running costs. They operate the
lamps more effectively giving a better and more
stable UV output. This helps prolong
the life of the lamp in operation.
Ironically
some lower quality UV's use well made lamps supplied
by trusted manufacturers' like Phillips. But even
these will suffer from the old style choke and starter
circuits. The lamps won't work nearly as well. And
they won't last as long.
Considering
that a UV lamp costs around £100
plus to replace, buying a cheaper unit will
end up costing you more in the long run.

When
to turn off your UV lamp
For
holiday homes where you know that you are not going
to be there for say 6 months at a time, we would
say to switch the unit off to save electricity and
lamp usage i.e. you would then get 2 seasons out
of a lamp - rather than one. (Lamps have to be changed
every 12 months)
When you return to the holiday home, you should
then re-sanitise your whole system with bleach (just
like when you installed your UV unit in the first
instance.
If
you are only leaving the house for a few weeks,
then it would probably be easier to leave the unit
on.
Depending upon the model of unit, the power usage
varies bewteen 30 W to 48 W so not a hugh amount.
