Q1. What are calcium scales?

Calcium scale is a hard, chalky substance that often adhered on metallic parts of water-operated machinery. It is particularly common in machinery and equipment that involves heat exchangers, such as boilers and cooling towers. Typical types of scale are calcium carbonate, calcium sulfate, calcium sulfite, calcium phosphate and calcium silicate.

Q2. What kind of problems are caused by calcium scale?

The scale deposits on inner surface of boiler, cooling tower and other heat exchangers within water pipework. It may reduce water flow that ends up with increase of water pump pressure and damage machinery and pipework.

Q3. Where does calcium scale likely to deposit?

Cooling towers may have frequent scale deposit issues, especially those that have high content of calcium in water.

Q4. Does scale inhibitor work?

Some strong scale inhibitors may have an environmental risk. They may also need chemical rinsing and other measures to address issues caused by themselves. Plus, the inhibitors may accelerate development of red rust and degradation inside water pipes, resulting in sky-high pipe replacement cost. The Non Scalor does not require operating cost.

Q5. How does the Non Scalor prevent scale deposit?

When water containing elements of calcium scale passes through a pipe fitted with a Non Scalor unit, calcium ions, such as sodium cation, will react with carbon dioxide in water and be oxidized into nano-particles of calcium. Once the chemical reaction occurs, calcium scales do not deposit in water system.
