It is usually specified in areas where the water hardness is 200 ppm or more. INW-O® can help protect new and existing systems from calcification. Protects water conditions “permanently” by dosing a very low level of stable zinc, through an electrolytic process that uses a zinc anode and a copper cathode. This procedure requires that the calcium carbonate crystals that are originally in the water, become a soft aragonite, which prevents the formation of deposits of hard calcite (lime).

INW-O® is easier to install and operate than ever before. This cost-effective and innovative device uses recommended electrolytic technology to permanently prevent the accumulation of lime, and has significant cost, energy and water savings compared to other anti-scale solutions. As a result, it is already installed in a large number of municipal, industrial and commercial facilities. The changes developed in the system include a simplified interface, more intuitive for the user, a controller and an organic LED screen.

The implementation of our technology implies an important modernization of hydraulic networks and has a direct impact on:

• More efficient and rational use of water
• Savings that can be higher than 60% in energy consumption
• Increase in productivity

INW-O® is an environmentally friendly solution to prevent incrustations that do not release sodium, or chemical products such as pH correctors or neutralizers. Sodium is a highly contaminating and harmful mineral, both for the facilities and for people who consume water with doses above the WHO recommended. In the case of hard waters for irrigation that are treated with traditional systems, a high sodium content affects the permeability of the soil. INW-O® avoids the spillage of water rejecting the environment.

INW-O® does not demineralize water. This is important for several reasons, but we will highlight two mainly: First, because some minerals present in water are necessary for human life. Second, because although the incrustations may represent a problem for the installations, the availability of an excessively acid and aggressive water increases the risk of corrosion, as this aggressive nature makes the formation of protective layers on some metals difficult. INW-O® is a system that prevents incrustations without modifying the balance of the supply water.

Compared to traditional salt water softeners, INW-O® has significant savings in consumables, maintenance and water. Our system does not require water or salt for regeneration, while the maintenance requirements are minimal. The filter simply needs to be emptied periodically. The zinc anode has a service life of approximately 10 to 12 years, after which the anode may require replacement to maintain optimum performance. As a result, an INW-O® 42mm system could save more than € 4,200 per year compared to a similar size salt-based water softener. The ROI (return on investment) is typically less than 12 months.

Once INW-O® has been put into operation, the possibility of alteration by unqualified personnel is reduced by the addition of tamper-proof screws. Health and safety considerations have also been taken into account, since wiring can only be accessed with a special tool.

A four-line organic LED display ensures that the values are easy to read in low light or far away conditions, which is very useful as units are often installed in difficult locations. In addition, the controller technology allows future firmware updates to be made quickly, with minimal downtime and interruption. It includes an optional BMS pulse splitter that allows the use of water to be controlled by the central management system of the plant or building.
