CI OS100 Catalyzed Oxygen Scavenger

Catalyzed sulfite that eliminates dissolved oxygen faster than standard sulfite in steam boilers and high-pressure systems

CI OS100 is the catalyzed oxygen scavenger for steam boiler systems where standard sulfite isn't fast enough. Its sodium sulfite base is enhanced with a proprietary catalyst that accelerates the oxygen-sulfite reaction at lower feedwater temperatures and during the load swings, startups, and fluctuating conditions where uncatalyzed scavengers lag behind and leave tube walls exposed. Where CI SP50 is the standard liquid sulfite scavenger for steady-state steam systems, OS100 is the upgrade for operations where feedwater conditions are less predictable and the operator needs oxygen removed on contact, not minutes later. Dosed into the makeup or feedwater line, it reacts immediately upon contact with dissolved oxygen and maintains consistent sulfite residual in the 50–100 ppm range when monitored properly — neutralizing oxygen before it reaches critical boiler surfaces.

Key points
  • Primary functionEliminate dissolved oxygen faster than standard sulfite programs
  • Performance focusFast reaction speed, low-temperature response, and upset-condition oxygen scavenging
  • Process targetSteam boiler feedwater, makeup water lines, and systems with high condensate return
  • Use environmentSteam boilers, manufacturing plants, food processing operations, power generation, and institutional heating facilities

Steam boiler treatment, in sequence

A steam boiler program is a sequence, not a single drum. Each step below addresses one failure mode; the products listed are the CI chemistries whose descriptions assign them that role. Selection, dosing and control limits depend on makeup water quality, pressure and condensate return — confirm with CI technical service.

01
Clean before treatingNew and freshly descaled boilers
Manufacturing oils and post-descaling residues must come out before treatment chemistry goes in. Non-phosphate detergent for steel systems; neutral-pH cleaner where aluminum or condensing heat exchangers would be attacked by alkaline cleaners.

BD 86 Non Phosphate Detergent

Non-phosphate pre-startup and post-descaling boiler cleaner that removes oil, grease and process contaminants

CI BD86 is the cleaning step that happens before the treatment program starts. New boilers ship with manufacturing oils and greases on internal surfaces. Recently descaled boilers have residual process contaminants left behind after acid cleaning. If those residues stay in the system when the boiler goes into service, they cause foaming, surging, and unstable water levels — operational problems that no corrosion inhibitor or oxygen scavenger can fix because the issue isn't chemistry, it's contamination.

CI Neutral Boiler Cleaner

Neutral-pH pre-startup and post-descaling cleaner for aluminum boilers, condensing heat exchangers and pH-sensitive systems

CI Neutral Boiler Cleaner is BD86's counterpart for aluminum systems — the pre-startup and post-descaling cleaner for boilers and heat exchangers where conventional alkaline detergents would attack the aluminum surfaces they're supposed to be cleaning. Working pH of 7.5 to 8.0 keeps the chemistry within the narrow band that aluminum tolerates, while chelating agents and non-foaming surfactants emulsify and remove the manufacturing oils, installation grease, and organic residues that cause foaming, surging, and poor heat transfer if left inside the system at startup.

No 20 Boiler Compound

Balanced sulfite boiler treatment for hot water boilers and closed systems

CI WT No. 20 is the broad-coverage boiler compound for hot water and chilled water systems built with mixed metals — steel, copper, and brass running in the same loop. Its multi-component chemistry handles several failure modes simultaneously: nitrite forms a protective oxide film against general corrosion, sodium sulfite scavenges dissolved oxygen before it can pit tube walls, phosphates and organophosphonates control scale deposition from hardness minerals, and alkaline agents keep system pH in the protective range for ferrous and non-ferrous metals together.

Key points

Condensate-line corrosion inhibitor for steam distribution and return systems

CI No. 45 is the condensate-side protection for steam systems — the treatment that protects everything downstream of the boiler after the steam leaves the vessel. When steam condenses, dissolved carbon dioxide forms carbonic acid in the return side of the system, and that acid quietly pits condensate lines, traps, and return piping until they leak.

CI No. 49 is the upgraded steam-system corrosion inhibitor for operators who need more than simple acid neutralization in the condensate return. Where No. 45 neutralizes carbonic acid, No. 49 adds a second line of defense: filming amines that lay down a hydrophobic barrier on internal metal surfaces. That means two protection mechanisms working together — neutralizing amines handle the acid chemistry, while filming amines help keep corrosive condensate from contacting the metal in the first place.

CI PD90 – Phosphate Boiler Treatment for Scale Prevention

Prevents calcium and magnesium scale before it forms in steam boilers and feedwater systems

CI PD90 is the scale prevention treatment for steam boilers and feedwater lines where calcium and magnesium hardness in the water would otherwise precipitate onto hot metal surfaces as mineral scale — the insulating layer that reduces heat transfer, increases fuel consumption, and eventually leads to tube overheating and failure. Active phosphate compounds sequester hardness ions and keep them in solution so they leave the system through blowdown instead of baking onto tube walls.

CI SP50 – Liquid Sodium Sulfite Boiler Treatment for Oxygen Control

Eliminates dissolved oxygen before it pits tubes and drums in steam boilers and high-condensate systems

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.

CI WT No. 38 is the dual-inhibitor treatment for closed-loop hot water and chilled water systems where the operator wants both fast passivation and long-film stability in one drum. It combines sodium nitrite, which rapidly passivates ferrous metal surfaces, with sodium molybdate, which helps maintain a more durable protective film over time. That makes it a strong fit for closed hydronic loops where corrosion and mineral deposition quietly reduce flow, cut heat-transfer efficiency, and shorten the life of pumps, piping, and heat exchangers.

0.5% phenolphthalein indicator for sharp alkalinity and basic-range titration endpoints

CI Phenolphthalein Indicator is a standardized 0.5% w/v solution in isopropanol used in acid-base titrations requiring a clean visual transition from colorless to pink in the pH 8.3 to 10.0 range. It is the endpoint indicator for alkalinity, hydroxide, and carbonate-bicarbonate determinations where a vague colour shift turns a routine test into operator guesswork.

Key points
  • Safety profileMercury-free; hazardous due to isopropanol carrier
  • Primary functionProvide rapid, unambiguous endpoint detection in moderately basic titrations

Sulfite Test Kit

Drop-count test kit for sulfite residual in boiler, cooling, and closed-loop water treatment programs

CI Sulfite Test Kit measures sulfite residual as SO₃ in industrial water systems where sulfite is used to control dissolved oxygen and limit oxygen-driven corrosion. Run on a 25 mL water sample , the test uses drop-count titration to endpoint, with each drop equal to 6 ppm sulfite , giving the operator a direct field check on whether sulfite residual is actually sitting inside the intended treatment range.

Key points
  • Use environmentField testing and routine industrial monitoring
  • System fitBoilers, cooling systems, and closed-loop water circuits

Sulfite Titrant High

Standardized high-range sulfite titrant for boiler and feedwater residual control

CI Sulfite Titrant High is a standardized analytical titrant for measuring high-range sulfite residuals in boiler and feedwater systems where sodium sulfite is used as an oxygen scavenger. In a 25 mL sample , each drop equals 10 ppm as Na₂SO₃ , giving operators a fast, repeatable way to verify whether sulfite residual is actually sitting inside the intended control range.

Key points
  • Use environmentMunicipal, industrial, and commercial water treatment operations
  • Safety profileMercury-free and not classified as hazardous
  • Primary functionVerify whether excess sulfite residual is being maintained for dissolved oxygen control
