?What is a Electronic water descaler
Electronic water descaler is a new technology that without any chemical changes to water and by imposing electromagnetic field into the water it prohibits scale formation in pipes and equipments .Also it gradually removes existing scales.
?How does the Electronic PAC descaler work
PAC unit produces electromagnetic waves at varying frequencies and amplitudes, which are induced to the flowing water in the pipe around which the antennae have been wound. As a result, variable electromagnetic fields are produced around the pipe. These fields cause the salts which are as ions in water to from sub-microscopic crystals, which are electrically neutral and suspended in water, Accumulation of these crystals forms nucleation seeds for the precipitation of calcium carbonate in the form of larger crystals in the body of the water. So, they will have no tendency to adhere to pipes and fixtures and remain suspended in water. Also, due to increase in solubility of water. the existing scales will become soft and will gradually break off and wash away in the flowing water.
:How it works
PAC Uses pre-programmed micro chips to Transmit pulses of oscillating electromagnetic wave form into the water at varying frequencies and amplitudes. Low frequency waveforms are emitted through coiled wires attached to the outside of the water pipe, which result magnetic field.Row of water in this field induces electric potential changes, and cause some of the salts in the water to from sub-microscopic clusters, which are electrically neutral and suspended in water.
By heating the water the clusters act as nucleation seeds upon which the calcium carbonate precipitates.
Instead of hard encrustration on pipes and heating elements that normally occurs when water is heated the precipitation tokes the from of tiny calcium carbonate crystals that are suspended in the water. These invisible fine crystals are carried away with the flowing water. According to “snow-ball phenomenon, the size of floating crystals det larder as water flows in the pipe line.Because the crystals have no surface charges and are electrically neutral, they have no tendency to be attracted to the pipe walls, shower heads, etc, and remain suspended until they are carried away with the flow of water.
By suspension of minerals from soluble state, the Solubility of water increases, because the molecules that were involved in the above mentioned process, are now free. The increase in solubility of water result in gradual removal of existing scale.
salts and minerals which where dissolved in water become suspended due to the effect of the electro-magnetic field generated by PAC unit in closed-circuit system.such as HVAC and cooling towers, the tiny crystals settle in the regions of low speed of flow(such as basin of cooling towers ). So.by regular blowdown, the settled tiny crystals must be drained in order to avoid saturation of the settled minerals Otherwise, the settlement may dissolve again in water and cause scale formation. PAC causes only physical changes in water and the changes are non-chemical, that is no nothing is added to the water or taken out of it. Therefore, no changes in water triste for drinking is felt Due In this fact PAC.
water conditioner not only is used for HVAC, but it is also applied for houses and residential complex, food industries and agriculture
Electricity consumption and its price is low as compared to similar products. Finally PAC is environmentally friendly.
?Where PAC descaler can the used
The application of PAC descaler is very widespread. PAC descaler can be installed in all systems in which hard water flows.
Where To Use
In residential units the most suitable places of installation of PAC electronic water descaler are :
۱-On the discharge line of pressure booster pump. 2-On the cold water inlet to the water heater. 3-on the discharge line of recirculation pump or discharge line from the boiler.
For steam boiler circuit the most suitable places of installation of PAC electronic water descaler units are: 1-On the boiler inlet pipe. 2-On the deairator inlet water pipe. 3-Where water softeners are installed on the make-up water line the PAC unit must be installed on the discharge line from the softener to the feed tank
For cooling tower circuits, the most suitable place of installation of PAC electronic water descaler unit is on the inlet and\or discharge line from the heat exchanger.
IMPORTANT NOTE: For both steam boiler and cooling tower systems, due to consumptior of steam and\or evaporation of water the suspended minerals in water settle at the bottom of the boiler and the tower. Regular blow down of boiler or draining of the tower must be done in order to avoid saturation of water with suspended minerals.
For solar panels: Scale works as a thermal insulator and it means a great problem in the heat exchange process. The most appropriate is to install one PAC unit at the inlet of each panel. If the water temperature exceed 60 C, it is necessary to repeat the treatment at the inlet to the accumulator If accumulator is equipped with an electric resistor, the treatment will prevent damages caused by scale when adhered to metals, avoiding corrosion and saving energy.
Agricultural irrigation: PAC descaling unit increases the production and improves plant growth.
PAC descaler unit causes the water surface tension to decrease. This results in better absorption of water by plant roots resulting less consumption of water by plant. Install one PAC unit on each line of distribution network.
In which situation we can use this system?
The usage of this system is very widespread. We can use it in all systems and equipments that are working with water.
What are the advantages of electronic water descaler?
It doesn’t make changes in water quality. It is easy to install and does not need any maintenance. Also, it has insignificant energy consumption, small volume, and compatible to environment and extends life of equipments.
THE BENEFITS OF USING PAC:
۱ -Prevents formation of fresh deposits in the plumbing system. 2-Removes existing limescale deposits from pipes, application and heat transfer surfaces. 3-Increases the heat transfer coefficient and saves energy. 4-Reduces Corrosion, So increases life of water system, pipe works and equipments. 5-Treated water appears to be have much like chemically, softened water. Soaps, shampoos and detergents lather better. 6-Needs no chemicals, only physical changes in water is produced. Causes no harm to environment and healthy minerals retained, so the cold water from the tap can be safely used for drinking. 7-Requires no plumbing for installation. Easy D.I.Y installation and requires no maintenance. Also can be installed on variety of pipe materials. 8-Self diagnostic watchdog chip for auto reset. 9-Occupies small volume and the running cost is negligible
What are the advantages to electronic water descaler as compared to ion exchange water softener?
No changes to chemical content of water, no change in drinking quality, no need for operator and maintenance cost, lower price, no water wastage, compatible with environment, easy to install without need for piping. These are just few advantages to mention.
What are the advantages of electronic water descaler over magnetic descaler?
The electronic descaler is used for pipes of large diameters, whereas for manufacture of magnetic descaler for larger diameter pipes there is some limitation. Also, iron particles present in water adhere themselves to inside the pipe where the magnetic descaler is installed. So, it causes blockage in the pipes. There is not much limitation to vary water velocity for electronic water descalers, whereas the magnetic ones can function only for fixed water velocity.
What is the power consumption of PAC descaler?
The power consumption is negligible and it varies from 2 to 20 watts for different models
What is the power consumption of PAC descaler?
The power consumption is negligible and it varies from 2 to 20 watts for different models.
What is the effect of pipe material on the performance of PAC descaler?
PAC descaler performs well on all types of common pipes. But, for metallic pipes, shortening the antennae to the pipe surface (according to the instructions in the catalogue) results in better performance.
Where PAC descaler can be installed?
This unit must be installed on the cold water pipe connected to the system, and at the discharge side of the pump. Referring to the “place of installation” catalogue, sufficient explanation is given about the most suited places of installation
How electronic descaler removes existing scales?
Increase in water solubility result in dissolving existing scales, which adhere to the suspended microscopic particles of calcium carbonates known as “snow balls”.
What size do the suspended calcium carbonate particles have?
These particles size about 2 to 20 microns and cannot be seen by Unarmed eyes.
How can we remove these suspended particles of calcium carbonate from water?
Use of micron size filters will easily collect these particles. Also, in low pressure and low velocity areas of system, such as basin of a cooling tower, these particles will settle down and can be removed by regular blow downing.
How far from pump should electronic descaler be installed?
It must be at least one meter away and at the discharge side of the pump and before the system.
