Once
a heating system has been power flushed to remove sludge
and corrosion deposits, it is important to protect it
from further deterioration.
This
can be achieved by treating the system water with SYSTEMSAFE-DM,
a balanced blend of corrosion and scale inhibitors, formulated
to provide complete protection against system corrosion
and scale formation. It gives long term protection to
central heating systems, preventing internal corrosion,
scale deposition and boiler noises. It extends the life
of systems and maintains operational efficiency.
At
the end of the power flush, and before disconnecting
the CLEARFLOW® pump, SYSTEMSAFE-DM should be added
to the CLEARFLOW® tank and circulated through the
system for a further three minutes before disconnection.
Use one litre per 100 litres system water content, or
1% dosage rate by volume.
Application & usage:
To
ensure that all SYSTEMSAFE-DM enters system, add to the
feed and expansion tank after isolating water supply
and draining off 15 litres (3 gallons) of water. Allow
system to re-fill.
Alternatively,
SYSTEMSAFE-DM may be introduced directly into a radiator,
using a SYSTEMSURE injector unit.
New
Systems: Before adding SYSTEMSAFE-DM
to a new system, we recommend a pre-commission cleanse
with SYSTEM PRE-CLEAN to
remove installation and manufacturing debris such
as swarf, grease and jointing paste, to mobilise
and remove any dust and dirt, and neutralise any
acidic flux residues.
Existing
Systems: It
should be noted that no corrosion inhibitor can reverse
previous corrosion damage, and to optimise the system
efficiency, and allow SYSTEMSAFE-DM to work to best
effect, we advise that the system should first be
flushed with POWER FLUSH FX2 or HYPER-FLUSH.
This is particularly important in cases where a new
boiler or heat exchanger is being added to an older
installation.
Correct
dosage: The exact dosage rate is not critical,
as SYSTEMSAFE-DM will work effectively within a +/-
20% range, but a Systemsafe-DM test kit is available
to check for optimum treatment level. The test kit
determines the level of molybdate, which will be 330
ppm at the standard dosage rate. The kit contains reagents
for approximately thirty tests, together with sampling syringe and test tube with colour
chart and instructions.
