SpiroCare Water Chemistry
In both open and closed cooling and heating systems, water is one of the most important components of the installation. Often, the interchange between the water chemistry (such as the pH value, oxygen and calcium quantities), the mechanical components (pipes, radiators and heat exchangers) and the physical characteristics (such as pressure and temperature) of the installation is often insufficiently known or is underestimated.
However, this can lead to problems with potentially poor heat transfer, mechanical failures, a high degree of maintenance or a shorter service life, which ultimately has a negative impact on the energy and operating costs. The water chemistry is an important component and requires knowledge of the principal properties of water and the potential effects, such as the formation of scale and corrosion.
What you need to know about VDI 2035!
The VDI 2035 is a guideline regarding the design, installation, filling and maintenance of heating systems (< 100°C) in buildings.
Today’s energy efficient heating systems require a good heating water quality: small and compact heat exchangers are more sensitive to hardness and efficient pumps and valves are more sensitive to dirt.
Note that the warranty of the components in your heating system relies on the quality of your system water according VDI 2035!
