NOTE:
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, be- cause 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 corrosively of the water from which it is prepared and may become
increasingly corrosive with use if not properly inhibited.

6.4.1. Fluid Cooler Information
The information regarding fluid cool
er (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 Operation, Installation and Maintenance manual, which should be
referred to for more complete details.
