Steam Boilers and High-Condensate Systems | Eliminates Dissolved Oxygen Before It Pits Tubes and Drums | Liquid Sulfite That Feeds Clean Without the Plugging Problems of Powder

CI SP50 is the oxygen scavenger for steam boiler systems — it chemically reacts with dissolved oxygen in the feedwater and removes it before it reaches tube walls, drums, and piping where it causes pitting corrosion that leads to tube failures, unplanned shutdowns, and expensive pressure-part replacements. Dissolved oxygen is one of the most destructive forces inside a steam boiler, and every other treatment in the program is compromised if oxygen isn’t controlled first. Liquid format eliminates the operational headaches that come with powdered sulfite — no undissolved solids plugging feed lines, no inconsistent dosing from clumped material, no residue accumulating in chemical feed equipment. It mixes uniformly, feeds reliably, and keeps the dosing system running without the maintenance interruptions that powder-based scavengers create. Particularly effective in systems with high condensate return, where oxygen ingress through the condensate system puts internal metal surfaces at ongoing risk and consistent scavenging is the difference between stable operation and accelerating corrosion. By keeping oxygen out of the boiler water, CI SP50 also reduces the corrosion products that contribute to scale formation and heat transfer resistance — protecting fuel economy alongside metal integrity. Compatible with other CI boiler treatment chemicals and integrates into automated or manual feed programs. None of the other treatments in the water treatment line replace what this product does — No. 20, No. 25, No. 34, and No. 38 protect metal surfaces from corrosion through passivation films, but CI SP50 removes the oxygen that attacks those surfaces in the first place. Different job, different mechanism, and in steam systems, it’s the one that runs every day.
