As well as being a service company Pisces also manufactures and supplies a range of high-quality boiler water treatment chemicals for India and export customers. Our chemicals are suitable for land, marine and heritage steam boilers.

A badly treated steam boiler is a potential bomb, so getting the feed water quality and boiler water chemistry correct is critical and that means using tried and tested boiler water treatment chemicals.

A complete water treatment programme for a steam boiler will usually include a chemical oxygen scavenger, alkalinity builder and polymer sludge conditioner and, depending on the application, may also incorporate a phosphate treatment and a condensate line treatment

A boiler antiscalant is a specialized chemical formulation designed to prevent the formation of hard mineral scales inside boilers — especially on heat transfer surfaces. Scale buildup, usually caused by calcium carbonate, calcium sulfate, silica, and magnesium salts, acts as an insulator, reducing heat transfer efficiency and increasing fuel consumption.

✅ Prevents scale buildup — Controls calcium, magnesium, silica, and iron-based scales.
✅ Enhances heat transfer efficiency — Keeps boiler surfaces clean, ensuring optimal heat exchange.
✅ Reduces downtime and maintenance costs — Minimizes the need for frequent descaling and repairs.
✅ Extends boiler lifespan — Protects tubes and heat exchangers from damage caused by scale-related overheating.
✅ Improves steam purity — Reduces carryover, ensuring cleaner, higher-quality steam.

It works through three core mechanisms:

�� Threshold Inhibition: Prevents dissolved salts from crystallizing, even beyond their normal saturation limits.
�� Crystal Modification: Alters the structure of any crystals that do form, making them soft, non-adherent, and easy to remove.
�� Dispersing Action: Keeps suspended particles and scale-forming salts dispersed, preventing them from settling and hardening.

Oxygen scavengers are chemical compounds designed to remove or reduce oxygen from a system — typically to prevent oxidation, corrosion, or spoilage in industrial processes, packaging, or water treatment. Let’s dive into the details:

It’s a substance that reacts with oxygen — either chemically or catalytically — to eliminate oxygen from a gas or liquid environment. This prevents oxidative degradation of products or materials.

✅ Prevents corrosion: In boilers, pipelines, and water systems by eliminating dissolved oxygen that causes rust.
✅ Extends shelf life: In food packaging, it prevents oxidation that leads to spoilage and off-flavors.
✅ Preserves product quality: Protects sensitive pharmaceuticals, chemicals, and beverages.
✅ Supports anaerobic environments: Useful in industrial fermentation and biological processes where oxygen disrupts performance.
✅ Improves system efficiency: In steam boilers, it helps reduce scaling and pitting, enhancing equipment lifespan.

1️⃣ In Water Treatment & Boilers:

• Sodium sulfite (Na₂SO₃) — Reacts rapidly with oxygen; commonly used in low-pressure systems.
• Hydrazine (N₂H₄) — A powerful scavenger that also forms nitrogen gas, but it’s toxic and increasingly restricted.
• Carbohydrazide — A safer, less toxic alternative to hydrazine.
• DEHA (Diethylhydroxylamine) — Dual-action as an oxygen scavenger and metal passivator, especially in high-pressure boilers.
• Ascorbic acid — An eco-friendly, food-grade option for sensitive systems.

2️⃣ In Food & Packaging:

• Iron powder-based sachets — Common in food packaging to absorb oxygen and prevent spoilage.
• Sodium erythorbate — An antioxidant used in cured meats to maintain color and freshness.
• Enzyme-based scavengers — Natural alternatives using glucose oxidase to consume oxygen in packaging.

3️⃣ In Oil & Gas Industry:

• Ammonium bisulfite (NH₄HSO₃) — Effective for oxygen removal in oilfield water injection systems.
• Sodium metabisulfite (Na₂S₂O₅) — Common for seawater deoxygenation in offshore drilling.

Sodium polyacrylate, with the chemical formula of (C3H3NaO2) n, is a new functional polymer material and important chemical product. The solid product is white powder. It is often used as water treatment agent, brine refining and latex thickening. It can also be used as food tackifying and emulsifying.

This strain of water-soluble polymer, have extremely strong thickening water function, product purity is high, the performance is very stable, odourless, tasteless, far not corruption, "in the United States FDA, the Japanese ministry, the ministry of health of China approved the use of food additives, harmless to human body, easy to preserve and storage, as non-dangerous goods.

Sulfamic acid-based descalers are powerful cleaning agents designed to dissolve scale, rust, and mineral deposits from equipment, pipes, and heat exchangers. Let’s break it down:

It’s a water-soluble, crystalline, non-volatile acid (H₃NSO₃) that effectively breaks down calcium carbonate (CaCO₃), magnesium salts, rust (iron oxides), and other deposits without releasing harmful fumes like hydrochloric acid would.

✅ Strong descaling power: Quickly dissolves limescale, rust, and mineral deposits.
✅ Non-fuming: Safer than hydrochloric or nitric acid alternatives — no toxic vapors.
✅ Safe on metals: When formulated properly with inhibitors, it’s gentle on stainless steel, copper, and mild steel.
✅ Long shelf life: Stable and easy to store as a powder or liquid formulation.
✅ Eco-friendlier: Breaks down into environmentally acceptable residues compared to harsher acids.
✅ Prevents re-deposition: Often combined with dispersants to stop loosened scale from settling back onto surfaces.

1️⃣ Industrial Descaling:

• Boilers, heat exchangers, condensers, and cooling towers.
• Pipes and water-carrying systems prone to limescale buildup.

2️⃣ Food and Beverage Equipment:

• Safely removes calcium and magnesium deposits from dairy, brewing, and food processing machinery (food-safe versions available).

3️⃣ Household & Commercial Cleaning:

• Descaling kettles, dishwashers, coffee machines, and HVAC systems.

4️⃣ Metal Surface Cleaning:

• Removes rust and scale from machinery and fabricated metal parts.

Fireside chemicals for boilers are used to remove soot, slag, and carbon deposits from the fireside surfaces, enhancing heat transfer and improving boiler efficiency. These chemicals are typically in powder or liquid form and are introduced into the combustion process or applied manually to the affected areas. Here's a breakdown:

1. Soot Removers:

   • Composition: Often contain oxidizing agents (like magnesium or ammonium compounds) that break down soot and carbon deposits.
   • Function: React with carbon deposits to form lighter, less adherent compounds that are easier to clean or burn off during operation.

2. Slag Conditioners:

   • Composition: Contain compounds such as magnesium oxide or aluminum silicates.
   • Function: Modify the properties of slag to make it less sticky and easier to remove.

3. Catalytic Agents:

   • Composition: Include catalytic compounds that enhance the combustion of soot deposits.
   • Function: Promote complete combustion to reduce unburnt carbon residues.

1. Manual Application:
   • Fireside chemicals can be applied as a powder or slurry directly onto the sooty surfaces during maintenance shutdowns.
2. Injection During Operation:
   • Chemicals are introduced into the boiler through the burner or directly into the combustion chamber, allowing them to react with soot during operation.

• Improved Efficiency: Cleaner surfaces improve heat transfer.
• Reduced Maintenance Costs: Prevents heavy soot buildup, reducing the need for frequent manual cleaning.
• Extended Equipment Life: Minimizes corrosive effects caused by soot and slag.
