Cycle of Concentration | Cooling Towers | Cooling Tower C.O.C. |

COC or the Cycles Of Concentration is an abbreviation, used when talking about cooling water or cooling tower water. The COC specifies, how often a fresh water added into the loop, can be used or pumped around, before the water has to blown down or bleed off from the cooling tower.
~~EXAMPLE~~
The COC specifies the relation in between the concentration of minerals in the feed water and the cooling water.
So assumed the feed water has 100 TDS and the cooling water in the loop has 400 TDS, "Then COC will be 4."
|| As higher the COC as less fresh water is needed for replacement.||
