Pools and spas are very costly and time consuming to take proper care of. By installing a LKC Swimming Pool / Spa Treatment System you will reduce the amount of chemicals needed to treat your equipment by around 30%. Your water will be more clear and it eliminates the water rings around your pool! It also increases the life of your equipment, so payback of the unit is generally less than one year.

Ener-Tec's LKC Water Treatment System was originally designed as a non-chemical means of scale control in industrial water applications. After 20 years and over 7,000 applications later we have found that it is not only the most effective way to prevent scale buildup but has many benefits in the home market as well. Traditionally, permanent magnet systems have been used in the home market, but haven't been nearly as effective as electromagnetic systems. After many years of studying new permanent magnetic technologies and researching their effects, we have come up with an effective way for treatment of pools and spas. The benefits of using the Ener-Tec Pool / Spa Treatment System include:

  • Reduces chemical usage by approximately 30%!!!
  • Eliminates water heater problems.
  • Increases pump, filter, and plumbing life.
  • Increases filter performance.
  • Improves the clarity of the water.
  • Eliminates the ring around your pool, or keeps it soft enough to wipe off easily.
  • Solids will settle to the bottom making it easy to clean with a pool vacuum.
  • Less chemical usage makes your pool more healthy and much better for the environment.
  • Makes your pool feel like it's filled with softer water!
  • 1-year performance guarantee
  • 5-year product guarantee


Principles of Operation

An LKC works on a basic magnetic principal. In short, what it does is polarize the mineral molecules in your water as dipoles. Think of the molecules as magnets each with a north and south pole. We have all tried to push magnets together and found that a north and south pole attract each other. If two molecules of calcium (for example) are polarized by an LKC then the south pole of one will attach itself to the north pole of the other. With a long chain of molecules attached to each other, they are unable to attach themselves to the walls of your pool (creating the ring around your pool). They remain in suspension and buildup is eliminated. Since the minerals are all in suspension it also reduces the surface tension of the water which has a softening effect on the feel of the water and increases the clarity of the water.

Figure 1A. Random molecules entering the LKC. Figure 1B. Molecules are polarized. Figure 1C. They emerge as dipoles and just like our magnet example they are bonded together. Now there is absolutely no electric charge available for them to grab onto the walls of your piping. Even with the elevated TDS levels no scale or corrosion can form.The magnetic charge of the molecules also remove the existing deposits.


Many sizes are in stock and ready for immediate shipment. Those that are not in stock will generally have approximately a one week shipment time.


Chemical treatment requires continuous monitoring, adjusting feed, servicing of feed equipment, handling, and extensive water testing required to maintain proper water chemistry. The Pool Treatment System is self monitoring and requires no maintenance.


Safety is the most feared part of using chemical treatment in water systems. There have been many cases of severely burned hands, arms, and faces of persons handling chemicals.

The LKC System requires no chemicals.

Places to use

The Pool Treatment System works in any size water system no matter what the size. Each system is designed to fit the need.


The Pool Treatment System requires little room for installation since the entire cell is placed directly into the water line.

Continuous Treatment

The Pool Treatment System operates automatically, 24 hours a day with no assistance or monitoring.

The LKC System requires no chemicals.


You can normally own a Pool Treatment System for the difference in savings from reduced chemical costs from one year of use.
