The Phasis device consists of the housing and a so-called ferrite ring. Within the ferrite ring a strong electric field is built up. Because water is conductive transmit this high-frequency voltage to all areas of the water network. With an oscilloscope this can also be easily checked.

High frequency means that the current frequency of the Phasis device oscillates almost 3,000 times faster than our normal alternating current. The constant rapid succession of these pulses causes the calcium and magnesium calcifying elements to split into tiny microcrystals and due to their surface structure they cannot build up to calcifications.

With increasing voltage, the range of the signal path and thus the effect of the high-frequency field in the water is increased.

Phasis acts against calcified heat exchangers

This is how effective the Phasis technology is! The dissolved lime no longer settles

Under the microscope, the crystallization of the lime is clearly visible under the influence of the Phasis high frequency field. The coarsely precipitated spongy lime (left) can settle down, forming lime deposits. The high-frequency electric field transforms the lime into tiny crystals, which are rinsed out in this way and do not stick.

The technology induces an electric field into the water pipe and the water contained in it. We do not use magnets or wires which are placed around the pipe. can be laid - we use the principle of a transformer in peace. A ferrite ring is connected by the The device is guided and placed around the tube without any intervention.

Such a transformer consists of a primary winding, a ferrite ring and secondary winding. If an alternating current voltage is now fed into the Primary winding is fed, the ferrite ring is charged with energy and in turn transfers the voltage to the secondary winding.

The secondary winding normally consists of many windings, but in individual cases it can also only consist of one winding. Now we adjust this Wrap straight out and thicken. Filled with water we see a water pipe as Secondary winding works.

The limescale protection technology follows this mechanism of action. The device works like a primary winding and uses the ferrite ring, to transfer a voltage into the water pipe.

Just as a transformer feeds a voltage into an electric circuit, the limescale-protection device such a voltage in the water pipe and then further into the entire pipe system.

The signal consists of series of exponentially decaying sine waves with frequencies of approx. 120 kHz. The signal sequence is set for a series used in applications such as lime protection and lime decomposition, flocculation of suspended solids and Reduction of bacteria in the water.

Application of the principle of the transformer at rest

A transformer consists of two coils wound around a ferrite core. The ferrite core consists of pressed iron dust, only has the task of directing the magnetic field that is created. Let us now imagine that the second winding consists of only one loop. Let us now replace this second loop through a water pipe, we still have a transformer. However, with the effect that we have induced an electrical voltage into the water, because the tube acts like a second winding. This is the principle of the transformer at rest.

In order to generate an adequate flow of electrons in an open conductor, it is necessary to provide a high frequency source for the conductor. The height of the frequency must be sufficient to ensure the voltage of a standing wave over the entire length of the conductor.

The oscilloscope image shows the special signals in the form of sine curves, as well as the changing orientation of the electrons in the conducting water (and pipe) at maximum voltage. The Acceleration is generated by the electromagnetic field. The electric part of this field is responsible for the formation of clusters, which later become known as Crystallisation nuclei prevent the formation of limestone deposits. This pulsating electric field is transmitted in the water. The lime protection device induces the pulsating alternating current along the length of the pipeline network and sends this current forward and backward through the pipeline. The The device works in both directions in and against the direction of water flow.

Why PHASIS lime protection works like a water softener

  • The signal has a far-reaching effect on the entire water supply system
  • Lime deposits are prevented by high-frequency pulses
  • Strong alternating current signal also works with standing water
  • Environmentally friendly, very low energy consumption
  • Measurable signal supply and verifiable function strength

Effects of Phasis

The PHASIS devices are active electronic limescale protection devices that do not change the water hardness, but the effect! Through the induction of high-frequency alternating current, the lime-causing elements calcium and magnesium are split into microcrystalline particles. These particles can no longer Lime crusts build up and are kept floating in the water. With the flow of water these are flushed out of the pipes and installations. On surfaces (Wash basin, shower, tiles, etc.) outside the pipes, only a fine dust is visible, which can simply be wiped away.

The result is a shiny surface, continuous water pipes and free aerators. The skin feeling is much more pleasant and less dry. Bath additives and also detergents protect more. Here the dosage can be reduced considerably.
