Is your cooling system
protected, or could it
look like this?
To prevent corrosion,

GUIDANCE ON GLYCOL ANTIFREEZE AND ITS
USE IN INDUSTRIAL COOLING SYSTEMS
1. Uninhibited glycol based products can cause
extensive corrosion damage to multi-metal systems. Please view our Antifreeze Articles & FAQ's section for examples of damage.
2. Water-Glycol systems without the correct inhibitors become acidic (pH drop) over time, leading to corrosion.
Borax (Sodium Borate) is sometimes used to counteract this pH change but in isolation is not a proactive corrosion
inhibitor.
3. Water-Glycol systems should be regularly
monitored to ensure the required parametres (glycol %, pH, corrosion inhibitor level etc.) are being maintained.
4. Automotive antifreeze should not be used
in industrial cooling systems, as the high levels of silicate therein can reduce heat transfer rates and precipitate
as sludge.
5. Water-Glycol dilutions should preferably
be made-up with demineralised water - which will help prevent scale and, in the case of stainless steel systems,
attack by chlorides. (Chlorides cause corrosive pits in stainless steel systems). If demineralised water cannot
be used then the next best solution would be 'softened' water, this will prevent scale but not attack from chlorides.
To help overcome chloride ion attack always maintain the minimum recommended inhibitor reserve.
6. CoolFlow Glycols contain a range of proven corrosion, scale and biological
inhibitors to maximise heat transfer efficiency and the operating life of industrial cooling systems.
