Cooling water treatment for open towers and closed loops.
Six treatments for scale, corrosion and fouling in cooling towers, condenser circuits and closed hot and chilled water loops. Made in our own plants in Fujairah and Athens.
What are you treating?
Why it matters
A cooling circuit loses efficiency long before it fails.
Every cycle of concentration raises hardness and dissolved solids in the tower. Closed loops stay quiet until a pump seal or an exchanger tube lets go. Both are cheaper to treat than to repair.
Scale
Calcium carbonate on a condenser tube cuts heat transfer and raises the energy bill.
Corrosion
Mild steel pipework thins from the inside, and corrosion products foul what is downstream.
Yellow metals
Chlorine and bromine strip ordinary copper inhibitors, and brass tubes start to corrode.
Fouling
Suspended solids settle where flow is slow and hide corrosion under the deposit.
Sheran manufactures six cooling water treatments at its own plants in Fujairah and Athens.
The range
Six treatments. Open tower or closed loop.

Where it acts
Every part of the cooling circuit.
Open systems are dosed continuously at the basin or the recirculation line. Closed loops are dosed to a residual and topped up with the make-up.
Make-up water brings in hardness, alkalinity and suspended solids.

Common questions
Open, closed and copper.
Open towers lose water to evaporation and blowdown, so they need continuous dosing with SC-CW-708, SC-CW-709 or SC-CW-704. Closed loops hold their water, so SC-CW-701 or SC-CW-702 is dosed to a residual and topped up with the make-up.
SC-CW-701 is nitrite based and is controlled by testing the nitrite residual, 600 to 1,800 ppm. SC-CW-702 contains no nitrite and suits loops with mixed metallurgy. Both can be used in glycol systems.
Only if the system has copper or brass and runs on chlorine or bromine. Oxidising biocides break down ordinary copper inhibitors. SC-CW-703 is halogen resistant and is dosed alongside the main programme.
Yes. Send a make-up and a circulating water sample with the system volume and cycles of concentration. We return the analysis with a dosing programme against it.
SC-CW-701, 702, 708 and 709 come in 30 kg and 200 kg drums and 1,000 kg IBCs. SC-CW-703 and 704 come in 25 and 200 litre drums and 1,000 litre IBCs.
Order
Tell us the system, we will tell you the programme.
Send the system volume, the cycles of concentration and your last water analysis. We will come back with a dosing programme and a price, usually within one working day.
