SYSTEMSAFE-IC is an economical and effective liquid corrosion and scale inhibitor for use in closed water systems to prevent corrosion, sludge and scale problems.
THE PROBLEM:
Corrosion, sludge and black iron oxide deposits in heating and cooling systems result from decay of the system metals.
The chemical action which causes the decay may result from poor system design, causing air / oxygen to be taken into the system water, the presence of corrosive residues such as flux and jointing compounds, bacterial action, or electrolytic action resulting from electrical contact between mixed metals.
Corrosion products usually give rise to sludge in areas of low flow, notably the lower central areas of radiators, and under floor pipework, and cause fouling and failure of zone valves, circulating pumps, radiators, valves etc.
Small particles may be carried around the system and deposit and build-up in boiler and heat exchanger waterways, leading to failure of boiler sections and heat exchangers.
In hard water areas, the initial fill of water and any subsequent topping up water will contain hardness salts, and it is prudent to ensure that these do not cause problems in higher temperature zones of the system.
THE SOLUTION:
SYSTEMSAFE-IC is a balanced blend of cathodic, anodic and non-ferrous corrosion inhibitors, incorporating a scale inhibitor to provide protection against scale formation. It gives long term protection to closed water systems, preventing internal corrosion, extending the life of the system, and maintaining its operational efficiency.
SYSTEMSAFE-IC protects against the formation of black iron oxide sludge which accumulates in low flow areas to give flow problems, and against electrolytic and oxidic corrosion which leads to localised and pin-hole corrosion and leaks.
SYSTEMSAFE-IC may be used with metals commonly used in heating systems, including ferrous metals, brass, copper, and galvanised steel, but not with aluminium radiators or heat exchangers.
APPLICATION & USAGE:
SYSTEMSAFE-IC should be added to the system at a dosage rate of 1 litre per 500 litres (110 gallons) of system capacity.
Further additions will only be required if water losses from the system occur.
It may be added via a feed and expansion tank, after isolating the water supply and draining off sufficient water to empty the tank, to ensure that all the SYSTEMSAFE-IC enters the water system. Allow system to re-fill.
Alternatively, SYSTEMSAFE-IC may be introduced direct into the system at a suitable point, using an injector or pump with an adequate head, after draining off sufficient water to compensate for the volume of SYSTEMSAFE-IC being added.
Correct treatment level:
The exact dosage rate is not critical, as SYSTEMSAFE-IC will work effectively within a +/- 20% range, but dosage rate may be checked by using a test kit to determine the level of sodium nitrite, which will be 500ppm at the normal dosage rate.
Guidance notes:
New Systems: Before adding SYSTEMSAFE-IC to a new system, we recommend a pre-commission cleanse with KAMSOLVE 28, to remove installation and manufacturing debris such as swarf and millscale, to mobilise and remove any dust and dirt, remove light rust from radiators and pipework, 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-IC to work to best effect, we advise that the system should first be flushed with HYPER-FLUSH in extreme cases.
This is particularly important in cases where new boiler plant or heat exchangers are being added to older installations.
