pipe descaler schematics

For many years, magnetic (or electromagnetic) water descaler devices have appeared on the shelves of home improvement and DIY stores across Europe. Despite numerous studies conducted by manufacturers and various consumer associations, none have definitively concluded on the effectiveness of commercial pipe descalers. Given that electronic devices of this type can be relatively expensive, particularly considering their materials, this project is being offered to readers. For a modest investment, it is possible to assess the condition of personal faucets, pots, and other pipes. The proposed device is comparable to high-end models available for purchase, incorporating a bi-frequency option that appears to be the most effective method for combating lime scale deposits.

An initial astable oscillator, based on a traditional 555 timer (IC3), operates at approximately 10 kHz when only capacitor C6 is active, meaning transistor T1 is in a blocked state. T1 is controlled by another astable oscillator, utilizing IC1, which operates at about 1 Hz. When T1 is activated by IC1, capacitor C4 is effectively placed in parallel with C6, reducing the frequency generated by IC3 to around 5 kHz. To generate high amplitude signals, the power supply employs a mid-point transformer in an unconventional manner, utilizing simple half-wave rectification. The first half of the secondary winding delivers 15 VAC, which, after rectification, filtering, and regulation by IC2, provides a stable 12VDC current to power the oscillators. The entire secondary winding yields approximately 40VDC after rectification, which is used to energize coils L1 and L2, wound around the pipe systems targeted by the device.

Following IC3, a high-voltage transistor (T2, such as a BF457 or equivalent) modulates this high voltage at frequencies of 5 or 10 kHz, depending on the state of IC1. An LED (D3) illuminates to indicate that power is present. Coils L1 and L2 are simple inductors made from insulated flexible wire, each consisting of approximately ten turns. These coils must be wound around the pipes carrying the water to be treated, with a spacing of about ten centimeters between them. Importantly, neither the material of the pipe system nor its diameter should significantly impact the device's efficiency. Interestingly, the coils have one end exposed, which may seem surprising. However, the primary aim of this project is to enable the construction of a device similar to those available in stores, allowing for personal experimentation and testing of its efficacy.For many years now, magnetic (or electromagnetic) water descaler devices have been showing up on the shelves of Home Improvement and other DIY stores all over Europe.

pipe descalers in a decisive manner. Since electronic devices of this type are relatively expensive (especially when we discover what they are made of!), we decided to offer this project to our readers. For the price of a few tens of pounds, you will be able to evaluate the state of your own faucets, pots, and other pipes.

The device we`re offering as a project is identical to top-of-the-line items found on sale; in other words, it includes the bi-frequency option because it seemed that would be the best way to fight lime scale deposits. An initial astable oscillator, based on a traditional 555, labeled IC3, functions at around 10 kHz when the only capacitor C6 is operating; in other words, when T1 is blocked.

The latter is controlled by another astable oscillator, based on IC1 this time, but which functions at about 1 Hz. When T1 is turned on by IC1, capacitor C4 is effectively in parallel with C6 which divides the frequency produced by IC3 by two, i.

e. to about 5 kHz. In order to have high amplitude signals, the power supply operates with a mid-point transformer utilized in an unconventional way, with simple half-wave rectification. The first half of the secondary delivers 15 VAC which, after being rectified, filtered and regulated by IC2, supply stable current of 12VDC to supply power to the oscillators.

The entire secondary makes it possible to have available, after rectification, approximately 40VDC which is used to supply power to coils L1 and L2, wound around the pipe systems on which the assembly will work. To do that, IC3 is followed by high-voltage transistor T2 (a BF457 or equivalent) which chops this high voltage to 5 or 10 kHz frequency depending on the state of IC1.

LED D3 lights up to signal that the power supply is present. Coils L1 and L2 are simple inductors made from insulated flexible wire, with about ten windings each. They have to be wound around the pipes carrying the water to be treated` and are spaced about ten centimeters from each other.

Neither the material of the pipe system, nor its diameter, should have any influence on the efficiency of the device. Paradoxically, these coils have one end in the air, which may surprise you as much as us but we indicated at the beginning of this article, that our goal with this project is not to explain the principle but rather to allow you to make the same device as those sold in stores, so that you can perform your own tests.
