To guarantee a long life span for modern heating systems, all manufacturers give comprehensive tips and directives. These suggest demineralizing the filling water for every heating system. A reason for it are experiences from the practice, which underpin that already minimum steps of hardness in the filling water lead to damages in high-quality devices like gas-fired hot-water tank, warm pumps and solar arrangements. One of the most frequent causes is the amount of lime in the filling water. Using the example of a detached house with a heating system of 350 liters system water content results in average amount of 100g lime in the filling. Although this amount may seem small, it is able to damage by lime precipitation the built heating system permanently. The amount of lime increases, of course, with the amount of the used filling water. In addition, it varies from region to region due to the different degrees of hardness of the tap water.

Counteract corrosion from the beginning

Also damaging for sensitive devices such as heating baths is the penetration of the filling water with salts. Therefore, it comes to corrosion of the lines within the heating system. Electrochemical reactions have a harmful effect on the metallic parts of the system and accelerate the wear process. Benefiting from a high amount of salts the formation of galvanic elements is promoted that ultimately cause this corrosion. It also contained in the unfiltered water, chlorides, sulphates and nitrates have their not insignificant proportion.

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 Profi is especially for the heating engineer and the maintenance service 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 control console on the back is equipped with a pressure-reducing valve and a manometer. In addition, the Purotap profi system has a quantity counter for pipe water and can continuously switch between pipe water and desalinated water. It is equipped with wheels for better transport.

The lance of Purotap Profi system is made of long-lasting stainless steel and chrome steel. The filling speed is maximum 1500 liters per hour, filling capacity amounts to up to 4000 liters with average 20° German hardness.

All advantages of the mobile Purotap Profi 25 & 50 filling system are obvious

With the Purotap Profi 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 chrome steel, 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 44 kg.

The Purotap professional system made possible by its ease of use and the optimum overview during the softening and demineralization. Thanks to its good operation, it is suitable not only for professionals but also for the homeowner. With the space-saving designed filling station on wheels remains on the service vehicle space for other important tools.

The additional output on the bottom of the cartridge completes the program. Equipped with a safety sieve is a long life guaranteed. 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 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".
