England’s hydropet descaling technology

This technology is the only descaling that can work without the use of resin hardener and alone in air conditioning and industrial facilities. The most important success factor of Hydropet company in England since 1992 and in Iran since 2005 (2005) is the complete removal of resin hardener for hard water descaling. The complete removal of the resin hardener was initially met with opposition and ambiguity by experts and construction and facility supervisors, which is due to the inefficiency of similar magnetic sediment removers. Currently, chillers with a capacity of 4000 tons of refrigeration in Tehran since 1387 and 8000 tons of refrigeration in Kashan since 1390 are being operated with the removal of resin hardeners and without chemicals.

Currently, despite the high water hardness in all the projects of Radin Gostar Sina company, the resin hardener is removed from the circuit because it does not have the ability to remove sediment from Hydroflow. Hydropet UK hardener and descaling agent is able to produce radio waves with a frequency of 120 to 200 kHz and emit them stably in the piping circuit and related fluid. The emission of radio signals causes the formation of crystal particles inside the fluid, and these symmetrical crystals do not stick to the surfaces and move away from the critical area (heat exchanger, boilers, etc.) with the fluid flow.

Since both anion (carbonate and bicarbonate) and cation (calcium and magnesium) components are needed to create stable calcite crystals, which consists of calcium carbonate and magnesium, the use of resin hardener removes cationic salts. and the stoichiometric balance of anions and cations is disturbed and the performance of the Hydroflow descaling device is reduced. The importance of this unique technology in the world is due to the ability to use raw water with hardness and without the need to design sedimentation, hardening and water purification systems in industries. The volume of water in washing resins and reclamation operations is about 8 to 15% of production water.

Relationship between deposition and corrosion in hard water and soft water

Hard water and soft water show different behavior towards deposition and corrosion.

Hard water = high sedimentation – low corrosion

Soft water = low sedimentation – high corrosion

It is very difficult for the operator to create a balance between the sedimentation potential and water corrosion, due to the reciprocal relationship between them. Practically, during the use of resin hardener, by removing hard solutes, such as calcium and magnesium, and converting hard water into soft water, sedimentation is reduced, but the tendency to corrosion is greatly increased and requires the injection of chemical and anti-fouling substances. On the other hand, hard water has a high sedimentation tendency due to the presence of salts such as calcium and magnesium.

The only logical way to control these two problems at the same time (sedimentation and corrosion) is to use a solution that prevents sediment from settling in the equipment without changing the hardness of the water. In equipment and turning to chemicals and anti-corrosion. Hydroflow descaler is the only descaler that works directly with hard water and does not allow the formation of sediment and corrosion. With a simple decision, you can play your part in controlling sediment, corrosion and saving water.


Comparison of hydroflow descaling agent and resin hardener

In brief, the following headings show the comparison between Hydroflow descaling agent and resin hardener.


Comparison in terms of space required for installation

Resin hardener

It requires installation space in the engine room and service and maintenance space. This space should be considered in the economic comparison between two devices.


Hydroflow descaler:

It is installed on the existing pipes and does not require any additional occupied space in the engine room.


Comparison in terms of piping and execution

Resin hardener:

There is a need for additional piping in the potable water piping circuit to connect to industrial lines and expansion sources. The plumbing fee should be considered in the economic comparison.


Hydroflow descaler:

It does not require additional piping, and by removing the hard circuit piping, it reduces the implementation cost and installation speed.


Comparison in terms of shipping and installation and related costs

Resin hardener:

In addition to being time-consuming, the preparation, transportation and installation of resin hardeners are costly for the workshop.


Hydroflow descaler:

Hydroflow sedimentation devices are very small so that they can be carried and moved by hand and their installation is very quick and easy. It takes a maximum of 30 to 40 minutes for each industrial device.


Comparison in terms of consumables and recharging of resin and depreciation of parts

Resin hardener:

The life of resins is limited and 5 to 6 years depreciation of resins should be taken into account in the calculations of the investment return time.


Hydroflow descaler:

It has no consumable parts and the power consumption of the device is very small (25 to 55 watts).



Comparison of the effects of chlorine and chlorine shock

Resin hardener:

Free chlorine, which is used for disinfection, severely damages the resins and reduces their life. If the chlorine shock of 8 to 10 ppm is unintentionally hardened, the resins actually lose their effectiveness.


Hydroflow descaler:

Chlorine compounds or chlorine shock do not affect the anti-scaling performance of Hydroflow.



Comparison in terms of tolerance of maximum working pressure

Resin hardener:

The maximum working pressure of the resin hardener is 4 bar, and as the pressure increases, the resins lose their efficiency, so in high-rise buildings, either several hardeners should be installed or a soft water booster pump should be included in the hardener outlet to send to the floors. Soft water pump booster calculations and tank piping should be included in economic calculations.

Hydroflow descaler:

Hydroflow descaling agent can be used in any working pressure that pipes and equipment can withstand. Zero to 1000 bar or more, Hydroflow performance is independent of pressure.



Comparison in terms of contaminating and making water non-drinkable

Resin hardener:

Hardened water has substituted sodium salts, which is not suitable for drinking, so it is not installed in coil sources or plate converters, and the converters always have sedimentation problems.


Hydroflow descaler:

Hydroflow sediment trap does not change the chemical composition of water and PH and does not introduce any substance into the water and can be installed in all sanitary and non-sanitary installation circuits.



Comparison in terms of corrosion potential

Resin hardener:

By removing calcium and magnesium from hard water, its sedimentation rate is reduced, but its corrosion potential increases. Soft water or water that has zero hardness is highly corrosive. The amount of measurement of corrosion and deposition potential is measured by the deposition-corrosion index.



Hydroflow descaler:

Hydroflow hardener reduces the corrosion potential, in addition to not allowing the formation of sediment, it makes the internal surfaces positive by creating a high frequency current in the entire metal piping circuit. Hydroflow descaler is the only cathodic device for the inner surface of pipes.



Comparison in terms of dandruff and whiteness

Resin hardener:

The white scales that form on the outer wall of the faucets indicate improper backwashing with salt water, which causes the passage of salt water and chloride ions, and this causes the pipes to corrode.


Hydroflow descaler:

No element or chemical substance enters the water by the Hydroflow sediment trap, in other words, the Hydroflow sediment remover is a green technology and does not change the chemical composition of the water.



Comparison in terms of useful life of devices

Resin hardener:

The life of resin hardener depends on its components such as: metal body, sprinklers, valves, etc., which usually requires 6 to 7 years of overhaul due to increased corrosion and chlorine ions and other issues.


Hydroflow descaler:

Hydroflow descaling agent has a lifespan of more than 30 years. Hydroflow household devices and descalers have MTBF of about 4.36 years, and the industrial series has IP68 and is completely waterproof and dustproof.



Comparison in terms of environmental protection

Resin hardener:

Resin-hardened saline wastewater is one of the most important reasons for the loss of underground water and the blockage of underground layers. This salt water is one of the environmental violations in ISO 14001. Groundwater salinization is one of the main risks of destroying groundwater resources.

Hydroflow descaler:

Hydroflow sediment trap is a European green technology and does not contain any chemical substances or chemical effluents harmful to the environment.



Comparison in terms of saving water consumption

Resin hardener:

The resin hardener is saturated and needs to be regenerated and washed regularly with 10% concentrated salt water. The amount of bekwash is about 8-12% of production water, which causes water wastage of at least 8-12%.


Hydroflow descaler:

Hydroflow descaling agent does not need to be washed, and this saves about 8-12% compared to resin hardener.



Comparison in terms of performance in waters with very high hardness

Resin hardener:

The efficiency of resin hardener decreases with the increase of TDS and TH.


Hydroflow descaler:

Hydroflow descaling agent works even on sea water (TDS=4000ppm) and higher THs.



Comparison in terms of energy saving

Resin hardener:

The resin hardener reduces the slope of sedimentation inside the facility by producing soft water, but as hard solutes pass through the resin hardener over time, we see the formation of sediments inside the piping circuit and equipment. These deposits reduce heat transfer efficiency and increase energy consumption.


Hydroflow descaler:

Hydroflow descaling agent is a green technology that, in addition to preventing the formation of sediment, also separates old deposits of mineral salts from systems and equipment such as boilers, chillers, heat exchangers, and cooling towers.


Hydroflow descaling agent has many advantages over resin hardeners, which result in saving energy, not polluting groundwater, the environment, and not using chemicals.
