the special offer on the cartridges for water hardness control expires on August 31! Hurry up!
A professional knows very well that the correct water hardness reduces the risk of lime and rust inside the machine.
It doesn't matter if you put emphasis on the finished product or on the machine, the key point remains therefore always the same: the water must respect the right parameters to allow the barista to serve a perfect coffee to its customers.
Nuova Ricambi, specialist in spare parts for the espresso machine from 1980, pays special attention to the various water treatment systems and performs numerous laboratory tests on various products, to look for those that maintain mostly unchanged the pH of water.
Until August 31st, registered customers on Nuova Ricambi website can buy at a discounted price the kit to test the water hardness and 2250l cartridges, the 2250l under sink cartridges and the 3800l cartridge. In promotion also the Digital liters counter that instantly measures the water flow (in liters or gallons) and with a LCD display that indicates the volume of water passing by and the reached capacity limit in the filter work.
The metal parts of which the espresso machine is made are in fact subject to two different reaction types, depending on water hardness (calculated from the concentration of calcium salts, magnesium salts and dissolved minerals) in which are immersed:
- Excessively high hardness level: the presence of high quantities of minerals in the water facilitates the process through which the hydroxyl ions, in contact with ferrous ion, form a ferrous hydrate which, in turn, come into contact with oxygen triggering a process of oxidation and becomes what is commonly called rust (which is basically a change of iron status, from solid to dusty) that, slightly soluble, precipitates on the metal. The water electrical conductivity, and therefore the corrosion rate, increases as the amount of dissolved salts raises.
- Excessively low hardness level: when the demineralized water (status 'neutral') comes in contact with the ferrous ions that diffuse from the anode, tends to increase its level of acidity, and if the ferrous material presents the areas of oxidation, the water attacks the oxide layer, dissolving. The dissolved oxide will lead to the first scale formation.
It must also be remembered that it is difficult to work in an isolated environment, and that the oxygen and the carbon dioxide present in the air melt quickly in the water, facilitating the process of oxidation of the iron to rust.
The repair technicians around the world know the importance of saving the machine from limestone and rust, the main causes of wear and damage to the espresso machine. Nuova Ricambi is working alongside them to ensure longevity and proper functioning of the machines: takes advantage of this special offer!
