Since 1989 equipment is being manufactured to prevent mineral scale precipitation by using a coil wrapped around the liquid carrying pipe. Mineral ions in the liquid will be effected by the generated magnetic and electric field, starting precipitation (crystal growth) in the bulk of the liquid, rather than on pipe walls or other surfaces. These crystals will go down the drain or stay suspended in the liquid in case of a circulation system like cooling towers or heat exchangers. Good results have been achieved in shell and tube heat exchangers, small and large cooling towers, condensers and compressors in power plants, steam boilers, process water etc...
Existing mineral scale layers are gradually removed, increasing the temperature differential for cooling towers and heat exchangers. Often a payback time of less than one year is achieved.
Advantages of the product:
- Less corrosion in pipework
- Prevents settlement of zebra mussles (shell fish) in plants using sea or river water for cooling purposes.
- Bacterial counts in cooling systems will be less due to the fact that the breading ground (scale layers) for bacterials is taken away.
- Reddish water and rust in iron pipes will disappear.
Other beneficial effects of the treatment:
- No plant shutdown for installation
- No chemicals needed
- No maintenance of the equipment.
- Low power consumption
- Capital equipment will last longer
