what's really in your system water?

A free on-site test of your heating and cooling system water for hospitals, hotels and other commercial buildings.

No system shutdown. Results against your national standard. No commitment.

Not available for private homes.*

what we measure on site

Our specialist tests your heating and cooling system water on site with professional equipment and compares the results with the standard that applies in your region. You get clear, standards-referenced results while the specialist is still on site.

pH

Whether your system water is creating conditions for corrosion

conductivity

Dissolved minerals and salts that speed up corrosion, especially between different metals

water hardness

Calcium and magnesium that turn into limescale on heat exchangers

oxygen and magnetite

Signs of air ingress and the corrosion debris it leaves behind

System water tested and treated at Groene Hart Hospital
“The quality of the system water is better, and the risk of wear and tear due to contamination is lower, as is energy consumption.”
Marcel van Beek, Senior Mechanical Engineer, Groene Hart Hospital, the Netherlands
 
Result: no more clogs causing outages, lower energy costs, and a technical team that moved from reactive repairs to planned maintenance.
