NOTICE: Risk of corrosion can cause equipment damage. Contact a water
consultant about water quality, corrosion and freeze protection requirements.
Water chemistry varies greatly by location, as do the required additives,
called inhibitors that reduce the corrosive effect of the fluids on the piping
systems and components. The chemistry of the water used must be
considered, because water from some sources may contain corrosive
elements that reduce the effectiveness of the inhibited formulation.
Preferably, surface waters that are classified as soft and are low in chloride
and sulfate ion content should be employed. Proper inhibitor maintenance
must be performed to prevent corrosion of system components. Consult
glycol manufacturer for testing and maintenance of inhibitors.
Commercial ethylene glycol, when pure, is generally less corrosive to the
common metals of construction than water itself. It will, however, assume the
corrosivity of the water from which it is prepared and may become
increasingly corrosive with use if not properly inhibited.
Internal (Fluid) Volume – Fluid Coolers
Fluid Cooler Information
The information regarding fluid cooler (or often referred to as a “dry cooler”) internal volume, the
volume of the inter-connecting piping and the freezing point of aqueous solutions can be found
in the individual Fluid Cooler User Manuals which should be referred to for more complete
details.
