Quaternary Ammonium Chloride
For Use in Water Cooling Towers

Hydratone #2793 prevents the accumulation of organic matter in water. It keeps water clear, improves heat transfer, and eliminates slime and malodors. It is particularly important in re-circulating systems.

Quantity Required
Initial Treatment
If water is clear or only slightly turbid……Use 1:5000 water
If water is turbid, slimy, or malodorous……Use 1:2000 water

Add anywhere in the system where it will mix thoroughly. Initial treatment may increase the quantity of suspended matter in the water; this indicates that Hydratone #2793 is cleaning the system. Removes suspended matter by skimming or cleaning filters.

Within one week, water should be clear, slime-free, and odorless. If not, repeat initial treatment until desired water quality is secured.

Regular Treatment
Once a week, normally, add Hydratone #2793……Use 1:10000 water

In hot weather, or if normal make-up water is added to the system, more Hydratone #2793 may be required. If water starts to become cloudy, add Hydratone #2793 at 1:10000 water TWICE a week until problem is corrected.
