Purotap

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.

Save with Purotap

The proven system Purotap offers an attractively priced solution to permanently counteract processes, to extend the lifetime of an expensive and high-quality heating system and to save you costly repairs. Depending on the model, disposable cartridges (Purotap 500, Purotap 1000, Purotap Mini, Purotap Micro) or special filling cartridges made of chrome steel (Purotap Easy, Purotap Profi) are used.

Within the Purotap series can be found a suitable solution for every need. From disposable cartridges on transportable filling stations to fixed refilling, everything is offered. Our many years of experience and the smooth exchange with users from the professional sector, but also the demands that the "simple" homeowners have in our products, has enabled us to meet all challenges with the Purotap system.

All advantages of the Purotap family are obvious

All Purotap systems 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".

Within the scope of DIN EN 1717 can be interposed easily a system separator.
