A descaling agent or chemical descaler is a chemical substance used to remove limescale from metal surfaces in contact with hot water, such as in boilers, water heaters, kettles and heat exchangers.

Descaling agents are typically acidic compounds such as ScaleAwaySFA^TM and ScaleAwayMSA^TM that react with the alkaline carbonate compounds present in the scale, producing carbon dioxide gas and a soluble salt.

Definition
   Descaler

Etymology
   Descale + er

Noun
Descaler (plural - Descalers)

1. That which descales (removes scale from surface)

ScaleAway^TM Descalers
ScaleAway Lime-Go^TM is used as an acidic cleaning agent, sometimes pure or as a component of proprietary mixtures, typically for metals and ceramics. It is frequently used for removing rust and limescale, replacing the more volatile and irritating hydrochloric acid, which is and highly corrosive on heat transfer equipment and very toxic and dangerous for your staff.

When compared to most of the common strong mineral acids, ScaleAway Lime-Go^TM has desirable water descaling properties, low volatility, low toxicity and is a water soluble solid forming soluble calcium and iron-III salts. Its also finds applications in the industrial cleaning of dairy and brew-house equipment. It is considered less corrosive than hydrochloric acid due to its lower pKa

ScaleAway Lime-Go^TM is a strong inorganic acid that is used in many industrial processes. The application often determines the required product quality.

One of the most important applications of ScaleAway Lime-Go^TM is in the pickling of steel, to remove rust or iron oxide scale from iron or steel before subsequent processing, such as extrusion, rolling, galvanizing, and other techniques. Technical quality ScaleAway Lime-Go^TM at typically 10% concentration is the most commonly used descaling agent for the limescale removal of carbon steel grades.

ScaleAway Lime-Go^TM concentrate can be used to regulate the acidity (pH) of solutions.
In industry demanding purity, high-quality ScaleAway Lime-Go^TM is used to control the pH of process water.

Because your water system contains the life blood of your production plant, descaling should be included in your preventative maintenance programme for the following crucial reasons:

1. It improves Plant Efficiency
2. Lowers Cost
3. Conserves Energy
4. Decreases Down-Time
5. Extends the Usable Life of Cleaned Equipment
