Scaling: 

Scaling occurs when a mineral film coats the entire heat transfer surface of Heat exchanger OR Condenser.   These mineral deposits such as Calcium, lime, Mud and rust rob heat transfer efficiency. This increases energy cost by over 30 %.

Heat Exchangers, Condensers and even Cooling Towers therefore require DESCALING maintenance to improve their efficiency.

Evaporative Condenser:

When water scale is deposited on the heat transfer surface of an evaporative Condenser, the cooling water from the spray head can not efficiently condense the refrigerant gas in the coils.  As a result inadequate cooling , over worked machinery and expensive operation is incurred.

Shell & Tube Condensers: Water scale deposits in the condenser coils cause the compressor to kick out on high head pressure and lowers the cooling capacity of the unit.

Cooling Towers:

• Basic principle of Cooling Tower is to cool the water that has picked up heat generated by equipment within facility.  Cooling tower design enhances evaporation & allows further cooling of tower water. This water is then pumped into the facility continuing to cool the equipment
• Scaling within cooling tower can restrict the water distribution of spray nozzles, reduce the water flow thru the openings of a hot deck and restrict the air flow within the tower.
• All these conditions result in diminished cooling capacity & inefficient operation of the associated equipment in the cooling tower system.

Absorption Units:

• Water scale accumulating on the water side of Absorbers & Condensers materially affects the operation and efficiency of any absorber type Air-conditioning unit.
• The harder the water, the faster the deposit accumulates.

Scaling of Plastic Molding  Machines :

• Cooling is an important process in the production of injection  mold
• To molders, scale, caused by calcium in hard water, is a devil that forms as   
• Water flows through pipes, contaminating and clogging lines throughout a plant.
• When scale builds up in the pipes and heat exchangers on a molding machine’s hydraulic system, it causes poor heat transfer, which prevents molders from running their machines at full capacity.
• Similarly, when scale clogs mold cooling water passages , it creates a thermal barrier that hinders the cooling and heating of the mold. All of this adds up to wasted machine time and money.
• Injection molding machines are typically run at about 65 to 75 percent of their fastest cycle times because of poor heat transfer.
• It takes just a 1/16-inch-thick build up of scale to cause a 15 percent slowdown in a machine’s cycle because it takes longer to extract the heat.
• A uniform cooling process is desired to avoid defects in manufactured parts.

How to Get Rid of Scaling :

• Scale can not be removed by hydro blasting or typical scrubbing.
• The only reliable way to remove these scales is by   Descaling Agent .
• 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, and kettles.
• Descaling agents are typically acidic compounds such as hydrochloric acid that react with the alkaline carbonate compounds present in the scale, producing carbon dioxide gas and a soluble salt. 
• Notable Descaling agents include acetic acid, citric acid, glycolic acid, formic acid, phosphoric acid, sulfamic acid and hydrochloric acid.
• Descaling process needs to be done frequently
• Chemicals are used. So additional expenditure.
• Plant shut down is required resulting in loss of production.
• Softening plant is required.
• Costly man power required.
• All this can be eliminated by using SCALE-AQUA , a unique online non chemical No power Descaling equipment.
