That was the situation plaguing Joe

maintenance operations at the Mourtain
Place twin-apa1ment towers in Montreal,
during the summer r11989.

Magnetic technology solves
costly problem
"Holley\WII is marf(eting a newwater
treabnent system that employs magnetic technology ratherthan chemicals
to control the behavior of process
waters.'Viens infonned lvanusech.
'1 will cost a fraction of the sum quoted
for the piping retroft and wll definitely
prevent scaling."
The HoneyYA!II method uses the Mag0-Pure WaterTreabnent System; a
new, non-electric mu~ permanent
magnet method that alters the cohesive
energy of calcium and magnesium
salts by influencing their colloïdal
behavior.
The crystals rernain in suspension,
ratherthan building up on the walls of
pipes. This allows them to be picked up
by the special Mag-~Pure filter incorporated in the water circuit.
Comfort levels quickly improved
for tenants
Mag-~Pure systems were installed at
the Mountain Place Towers and operated
throughout the summer of 1990.
"t was one of the warmes~ most humid
summers we've experienced in quite
a fewyears," recalls lvanusech."Asure

no trouble maintaining the chilled water

t\\0 montils in operation the system
performed just as Viens sa id it v.ould do."
The feedback from the tenants was
equally favourable. Ali agreed that it was
the most comfortable summer living
environrnent they had enjoyed in their
apartments in a long time.

Filters are easily replaced.
Overall results were better tllan
expected
"Operating costs have also reduced
considerably," comments lvanusech.
"Bk:Mdo\wt frequency is now once every
three weeks rather than daily as in
past years. Maintaining th pH level of
the water is much easier.There is no expenditure on chemicals any more. The *
compressor doesn't have to ~as
hard now and that represents quite a
saving in energy costs. There is no build
up of scale on the pipes. And the water
in the system at 5 microns is cleaner
than it's ever been."
"1 also have peace of mind knoWng that
the tenants are happy and that 1receive
compliments rather than complaints on
the buiding's comfort level."
"1 am exlremely pleased Mt1 the decision
1made" says lvanusech."Results to date
are much betterthan 1had expected."
