Manufacturers, Exporters, Suppliers of Boiler Chemicals in Bhutan

Innovacorp India Pvt Ltd is a manufacturer, exporter, and supplier of boiler scale inhibitors and sludge conditioners in Bhutan. Our range is designed to control hardness deposition and keep suspended solids fluid in industrial boilers — so they can be removed through routine blowdown rather than baked onto heat transfer surfaces. Scale on a boiler tube is not just an efficiency problem; it is a tube-failure problem waiting to happen. The right program starts with a feedwater analysis and a blowdown review, not a fixed dose.

Why Scale and Sludge Control Matters

Boiler feedwater carries hardness — calcium and magnesium — along with alkalinity and silica. As the water evaporates, these salts concentrate. When they cross their solubility limit, they precipitate: some form hard scale on the hottest surfaces (the tube wall), and some form soft sludge in the boiler water. Scale acts as an insulator and can lead to tube overheating and failure. Sludge, if not conditioned and removed, can bake onto surfaces or carry over with steam. Scale inhibitors and sludge conditioners are how a boiler program manages both — one at the crystal-growth stage, the other at the solids-handling stage.

Where It Is Used

• Low and medium-pressure boilers: Where feedwater hardness is the main scaling risk.
• High-pressure boilers: Where scale control has to be tighter and sludge removal is critical.
• Bagasse-fired and multi-fuel boilers: Where fuel quality and feedwater quality both vary across the season.
• Process industry boilers: Textile, chemical and food plants where steam quality matters for the product.
• Auxiliary systems: Feedwater tanks and economisers where hardness deposition can start before the boiler itself.

Types We Manufacture, Export & Supply in Bhutan

• Polymer-based scale inhibitors: Threshold inhibitors that interfere with crystal growth, slowing the deposition of calcium carbonate and calcium sulphate on heat transfer surfaces.
• Silica-specific scale inhibitors: For feedwater where silica is present; slows silica polymerisation and helps keep it in suspension.
• Sludge conditioners: Keep precipitated hardness and suspended solids in a fluid, non-adherent form so they can be removed through blowdown.
• Dispersants: Help keep fine suspended solids dispersed in the boiler water, preventing them from settling on tube surfaces.
• Phosphate treatment: For controlled precipitation of hardness in medium-pressure boilers, used with a sludge conditioner.

Specification Table

Property	Typical Range

Final specification is confirmed against the product datasheet and after a feedwater and boiler water analysis.

Application and Dosage

Dosage depends on feedwater hardness, boiler pressure, blowdown rate and the current treatment program. Indicative starting ranges:

• Scale inhibitor (polymer): 5 – 30 ppm in the boiler water, adjusted to the hardness and silica load.
• Silica-specific scale inhibitor: 5 – 20 ppm, tuned to the silica concentration and boiler pressure.
• Sludge conditioner: 5 – 20 ppm, adjusted to the suspended solids load and blowdown rate.
• Dispersant: 5 – 15 ppm, dosed continuously with the scale inhibitor.
• Phosphate treatment: Dose confirmed against the residual phosphate target for the boiler pressure.

Feed points and dosing method are discussed with your plant engineers. Final dosage is confirmed after a feedwater and boiler water analysis, and a trial on the boiler.

Packing

• 35 kg / 50 kg HDPE carboys and drums (liquids)
• 200 kg HDPE drums (liquids)
• 25 kg HDPE-lined bags (powders)
• 1,000 kg IBC tanks for large boiler houses

Key Benefits

• Helps control scale deposition on boiler heat transfer surfaces.
• Keeps precipitated hardness and suspended solids fluid for removal through blowdown.
• Supports stable heat transfer and reduces the risk of tube overheating from scale.
• Available in polymer, silica-specific and phosphate treatment options.
• Program design is confirmed through feedwater and boiler water analysis, not fixed dosing.

Technical Support

Scale and sludge control works only when the program matches the feedwater and the boiler operating cycle. We work with your plant engineers on feedwater and boiler water analysis, dosage calculation, blowdown review, and program reviews across the year. Final specification, dosage and packaging are confirmed after a water analysis and a boiler trial.
