Protect your closed-loop chilled and hot water systems from insidious corrosion, dangerous microbiological fouling, and catastrophic efficiency loss.
Because chilled loops are closed systems, problems often go unnoticed until pipes fail or chiller efficiency drops drastically. Black water and sludge are signs of active destruction.
Mixed metallurgies in closed loops lead to rapid galvanic corrosion. Without chemical buffering, mild steel piping oxidizes into damaging "black water" (magnetite) sludge.
Stagnant, unmonitored legs are breeding grounds for Sulfate-Reducing Bacteria (SRB). They produce hydrogen sulfide, causing severe localized pitting corrosion and foul odors.
Suspended iron oxides, microbiological slime, and construction debris accumulate in chiller tubes and air handling units (AHUs), blocking flow and destroying heat transfer.
We deploy a combination of robust passivating chemistry and mechanical filtration to keep your chilled water crystal clear and your piping structurally sound.
Our premium treatments establish a resilient passivating film on internal metal surfaces. We select the ideal chemistry—nitrite, molybdate, or advanced organic formulations—based on your specific system metallurgy and operating temperatures.
Closed loops require unique biocidal strategies because they cannot easily vent gases like cooling towers. We utilize specialized, long-lasting non-oxidizing biocides to penetrate biofilms and eradicate dangerous anaerobic bacteria (SRB).
