With Purotap Mini and minor effort save in the long term
As in closed heating systems actually no corrosion can occur, non-professionals are baffled with the question as to why did it come to serious damage due to corrosion. Benefiting from a high amount of salts in normal tap water, the formation of galvanic elements is promoted that ultimately cause this corrosion. But also in the unfiltered water containing chlorides, sulfates and nitrates have their share of such decay processes.
To counteract such processes permanently, to prolong the lifetime of an expensive and high-quality heating system, and to save you costly repairs the proven Purotap system offers an attractively priced solution.

The manufacturers give out regulations and technical guidelines for handling to any modern heating system. Each of those guidelines recommends demineralizing the heating water. Behind this are many practical experiences that clearly demonstrate that even minor levels of hardness in the filling water damage sensitive equipment such as gas boilers, heat pumps and solar systems. Decisive for the extent of damage is, among other things, the amount of lime in the filling. In the case of a detached house with a heating system of 350 liters system water content, an average of 100g lime comes together. The larger the amount of the filling water, the greater the amount of containing lime. The exact amount will of course vary from region to region with the exact hardness of the tap water.
Also in the filling damaging located salts act on such a modern heating systems. In closed heating systems can occur indeed actually no corrosion, but the practice shows that it happens anyway. The reason for this are electrochemical reactions in the tap water. Benefiting from a high amount of salts the formation of galvanic elements is promoted that ultimately cause this corrosion. But also in the unfiltered water containing chlorides, sulfates and nitrates have their share of such decay processes.
It is true that, at simple softened water, calcium and magnesium ions exchanged for sodium ions, thus removed from the water hardness, and significantly lowered the hardness grades, but the salinity of the water remains unchanged. In case of modern systems, an important damage factor remains completely unchanged.
The Purotap Mini finds space in almost every household and with the proven Purotap 500 and Purotap 1,000 cartridges offers not only an inexpensive and environmentally friendly method to demineralize water, it also stands out more for its user-friendliness and good workmanship. Equipped with a precise measuring computer, it is simple, to obtain accurate information about the status of water, the salt content and the degree of hardness. On request, it shall indicate the mineral content or the conductivity of the water and warns the user if the capacity of the cartridge is exhausted. The integrated flow meter displays the output per liter and ascertained the already treated water quantity in the heating system. The power supply takes place entirely using conventional batteries.

With the Purotap Easy system for refilling heating water according to VDI 2035 Elysator fills a real gap in service. In contrast to the usual demineralization cartridges, the complete demineralization can be controlled through a specially designed and battery-powered measuring counter. The station can be easily mounted on a wall and switch between tap water and filling water for the heating system. The exchange of the used resin cartridge is very simple and can be done with just a few clicks.
The Purotap Easy system facilitated by its easy use and the optimum overview during the softening and demineralization not only artisans but also homeowners significantly the everyday life.
The Purotap Mini System used in Purotap 500 and Purotap 1000 cartridges can also be easily disposed of in regular household waste. They contained no environmentally harmful additives or toxic chemicals. If desired, you can send us the empty cartridges for disposal.
The mobile filling station Purotap Profi fulfil latest requirements and quality standards. Including the Association of German Engineers (VDI) standard norm 2035, which states: “With decreasing water salinity increasing amounts of oxygen can be tolerated. In the absence of ions that can take over the transport of electric current in the water, is the formation of galvanic cells, which may lead to localized corrosion, virtually impossible. (…) For initial filling larger water heating installations using demineralized water is recommended.” However, the DIN 50930 of the German Institute for Standardization e. V. (DIN) paid full attention in developing the Purotap systems. According to this chloride and sulfate ions stimulate the anodic partial reaction of metal dissolution. By selective anion exchange the probability of local corrosion can be reduced.
Another fulfilled standard are the provisions of the Swiss Association of Heating and Air engineers (SKWI). The Swiss standard requires: “The filling and make-up water must be desalinated.” On top of that are the SKWI states that "the best technical solution is demineralization in waters with high chloride or sulfate content".
