Chemical cleaning of closed heating and cooling systems!
A thorough chemical cleaning ensures that the system functions optimally and extends its lifespan.
Why is chemical cleaning necessary?
Closed heating and cooling systems are designed to function for many years with minimal maintenance, but over time various problems can arise that require a thorough cleaning.
Corrosion, sludge, rust particles and microbiological growth can lead to reduced efficiency, clogged pipes, high energy consumption and, in the worst case, system failure. A thorough chemical cleaning ensures that the system functions optimally and extends its lifespan.

When should the system be cleaned - and is it always necessary?
If the system has poor water quality or inefficient operation, we first recommend a water analysis to determine if chemical cleaning is necessary. Sometimes adjusting water treatment and adding inhibitors may be enough.
Dry cleaning is not always necessary, but we recommend an assessment if you experience any of these points:
Poor circulation
Sludge and deposits can block pipes and valves
High energy consumption
Poor heat transfer increases costs
Frequent aeration and pressure drop
Signs of corrosion or air ingress.
Discolored or smelly system water
Indicates contamination or bacterial growth
New/rehabilitated system
Manufacturing residues and installation contaminants can cause problems
