Inspect
Identify the system, coil materials, existing condition, and manufacturer requirements.
A cooling-water additive that must be selected around the equipment, water chemistry, and current system requirements.

Dirt, deposits, and exposure can compromise heat exchange. Repeated cleaning addresses the buildup—but a complete plan also considers what happens between service visits.
Cool Flow works in approved cooling-water circuits. It is designed to improve wetting and heat transport in the circulating fluid; it is not applied as a photocatalytic surface treatment.
A water-side additive must be evaluated for fluid compatibility, concentration, corrosion control, and measured system performance. Photocatalytic activation is not the mechanism described for this product.
Identify the system, coil materials, existing condition, and manufacturer requirements.
Remove the relevant organic or mineral buildup with a compatible cleaning process.
Apply the selected product as directed; document baseline and follow-up operating conditions.
Proper cleaning comes first. Deposits left on a coil can limit coverage and performance. The cleaning process must be compatible with the coil and its protective finishes.
No. Continue inspection, filter changes, cleaning, and manufacturer-recommended service.
There is no single percentage that applies to every system. Equipment condition, load, weather, controls, preparation, and the measurement method all matter. Establish a baseline before evaluating a project.
No. Cool Flow is a cooling-water additive. Its system compatibility and dosing requirements must be checked separately from ThermalX.
