Chiller Makeup Water

Chiller Makeup Water

Cooling towers lose water through evaporation continuously, concentrating dissolved minerals in the basin. Without treatment, calcium carbonate and silica scale on heat exchanger surfaces — a 0.04-inch deposit reduces heat transfer efficiency by 40%. At the same time, stagnant warm water is a favorable environment for Legionella bacteria, making biological control a regulatory requirement in most commercial buildings under ASHRAE 188.

AMPAC USA supplies makeup water treatment systems for chiller and cooling tower circuits in commercial, industrial, and institutional facilities. Reverse osmosis on the makeup water supply dramatically reduces the mineral load entering the system, allowing cooling towers to operate at higher cycles of concentration before blowdown — cutting water consumption by 30 to 50% compared to untreated makeup.

For existing systems with established chemistry, AMPAC also designs side-stream filtration and chemical feed packages to control scale, corrosion inhibitor levels, and biocide dosing. Systems are sized to makeup flow rates, tower volume, and local water chemistry. All equipment is pre-assembled on a single skid for straightforward installation into mechanical rooms with limited floor space.

The economic case for RO makeup water treatment is straightforward for large cooling systems. Higher cycles of concentration mean less blowdown, less makeup water purchased, and lower sewer discharge costs. For facilities in areas with rising water rates or strict sewer discharge permits, RO makeup treatment often pays for itself within two to three years through water savings alone — without accounting for the reduction in chemical treatment costs and heat exchanger cleaning frequency.
