No minerals - no scaling

With Purotap easy and minor save in the long term

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.

PUROTAP ® easy

The Purotap cartridge filters drain the water from lime and aggressive substances in the water, such as sulfates, nitrates and chlorides. The device operates based on a mixed bed ion exchanger and supplies demineralized water in fully demineralized quality. This method adds no chemical additives to the water. The device works without external power supply and fulfills important guidelines such as VDI2035.

Counteract the usual corrosion

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 Easy is not only a portable solution to demineralize the water, but also captivates more by 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.

The lance of Purotap Easy system is made of long-lasting stainless steel and chrome steel. The filling speed is maximum 1000 liters per hour, filling capacity amounts to up to 1200 liters with average 20° German hardness.

Counteract the usual corrosion

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 high-quality filling cartridge is made of metal, sturdy and suitable for everyday use in the craft shop and at the customer site. Despite the high power capacity, the whole system does not weigh more than 18 kg.

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. It is ideal for the service technician who has to top up small amounts again and again. So must not be purchased expensive filling stations or measuring computers for each customer service vehicle.

The additional output on the bottom of the cartridge completes the program. Herewith the end user can take demineralized water for the household easily. It is suitable, for example, for the steam iron, to clean windows without water spots and for filling tanks, batteries or humidifiers.

The Purotap refill cartridges 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".
