Comparison of water conditioners
devices for electromagnetic water treatment
* - The efficiency of power transmission into the water (relative to WS)
** - Water conditioners with induction coils (wound around the water pipe)
The high efficiency of the water conditioner is primarily due to a new method of water treatment. It allows treatment of water not only at the aqueous solution resonant frequencies, but also at frequencies close to resonances. This increases antiscale treatment efficiency.
The water conditioner has an emitter with original design and ferrite plates made from advanced material with minimal losses. It thereby achieves of maximum efficiency of power transmission into the water.
The water conditioner is equipped with an extended self-test block. It measures the signal level and outputs it value using a digital indicator. In the case of incorrect mounting or contingencies, the water conditioner indicates this via indicator and audio. This allows mounting the water conditioner and monitoring its work without using special measuring devices, thereby reducing the skill requirements of the installer and the maintenance staff.
This water conditioner design has been around for over 20 years. However, its efficiency still remains at a high level, especially the model series "i" (industrial). The water conditioner inhibits limescale formation, corrosion and inner bacteria (biofouling) on the inner surfaces of equipment and pipes.
The electromagnetic field of the water conditioner is directed radially (across the axis of the pipe), and, due to the resonance effect, extends, according to manufacturer declaration, to a distance up to 0.4 mile (700 meters) on both sides of the installed device.
Status indication. The water conditioner has two indicators - "Power" and "Work". Although device installation is technically simple, achieving maximum results as well as controlling device signal parameters requires qualified installation and use of special measurement instruments.
The electronic water softeners with induction coils were designed about 30 years ago or even earlier. Over time their design has not changed much, but their efficiency is clearly insufficient (according to modern standards).
When assembling such an electronic water softener, one or several induction coils are wound on the pipe. The metal or plastic pipe become the core of this coil.
The power loss for magnetization of the core made of regular carbon steel may be 100 times or more. Therefore, the overwhelming part of the power of such electronic water softeners does not reach the water. It is not the fault of the manufacturer or quality of the components, but the physical principle of operation of such devices.
To increase treatment efficiency, manufacturers increase the number of coils to 4, 6, and even 8. However, this does not significantly change the situation.
Also, note that the direction of electromagnetic field lines of electronic water softeners with induction coils is along the tube axis. Therefore, the mounting of such electronic water softeners requires a straight pipe section. Its efficient distance is a little bit greater than the distance between the ends of the coils.
The careful coiling of a large number of wire turns, often in uncomfortable and cramped places, makes mounting such electronic water softeners a time-consuming and unpleasant task.
The presence of open (unprotected) wires (only insulated) and use of connectors from inexpensive materials significantly reduce the reliability of such devices. Coupled with the fact that the voltage in the coils can be up to 400V makes such electronic water softeners potentially unsafe.
Other antiscale devices.
In this group we include devices based on permanent magnets, electromagnets, devices with an electrostatic effect and so forth. In general, the effectiveness of these physical water softeners often is lower than the aforementioned. However, lets briefly consider some of them.
Devices based on permanent magnets. They are known for over 50 years. They require a "tie" in the pipe, so they are usually mounted during new pipe installation or pipe replacement. Some customers say there is a noticeable antiscale effect, but it gradually disappears a few months later. Probably, this explains the phrase regarding the effect - "adaptation to the water". But what it is and the reason for it - is unknown. For this reason, it is assumed that water softeners with electromagnets do not cause "adaptation to the water". Can we call this a scientific term? We do not know.
Last time on sale, there are devices with superstrong permanent magnets. They are most likely more effective than cheap samples. But how this overpayment is justified, we cannot judge. We would only note that the magnetic field of high tensions could be dangerous for humans and animals, for sensitive electronics - pacemakers, "smart watches" and so forth.
