Preventing Pinhole Corrosion (Chilled Water Piping) Several hospital chillers were developing pinhole leaks in cooling coils, traced to dormant “dead legs” in the piping layout. Dead legs are unused pipe sections where water stagnates, fostering bacterial and corrosive attack. Our survey identified six long dead-leg branches. Following best practice, we…

Reviving an Aluminum Closed-Loop System (Factory Cooling Loop) A facility’s semi-open, closed-loop cooling system (with aluminum piping) was fouled by iron deposits: water analysis showed elevated dissolved iron. We recommended a dynamic flush with a non-acid cleaning solution to remove the sludge. As industry literature notes, iron is “the most…

Boosting Cooling Tower Cycles (Manufacturing Plant, 5-Year Impact) A large industrial cooling system was running at only ~3–4 cycles of concentration (COC), causing excessive blowdown and corroded exchanger coils. By introducing an advanced Nalco treatment program, we raised the COC to ~10 over five years without scale or corrosion issues.…
