Creating the most effective corrosion and deposit control in evaporative cooling circuits comes with considerable inventory, manufacturing and treatment costs. To aid with the simplification of corrosion and deposit control development, those involved in water treatment frequently employs a range of models. Formulators are additionally concerned with cost reductions which maintain minimal environmental impacts and do not compromise product performance. This article thus elaborates on the new chemistries developed which form the basis of a simplified, flexible range of all-organic cooling circuit formulations that achieve high corrosion and deposit control performance.
