Some advice on
HOW TO PROPERLY TREAT A HEATING SYSTEM
in accordance with UNI CTI 8065 / 8364 / 8884
On new systems
1) Cleaning: before loading the system carefully wash the system until water is perfectly clean or better carry out a pickling cycle, i.e. removal of oxides and processing residues (oil, shavings, hemp residues, bad-quality paste, etc.) from metal surfaces. Always remember that new does not mean clean!
| OPERATION | PRODUCT/EQUIPMENT | RESULT | |
|---|---|---|---|
| Washing |  |
POMPA DISIFLUX | Circulator is preserved |
| Pickling | |
FERRONEX (non-acid product) | Surface oxides and impurities are dissolved |
2) Protection: Protect the system against corrosion/frost according to the following table:
| PRODUCT | RESULT | PRODUCTS TO BE ADDED AND CHECKS | |
|---|---|---|---|
| a) NO ANTIFREEZE PRODUCT | |
System NON PROTECTED against frost and corrosion |
FILMAX + Thermakil® Checks in accordance with STANDARD 8065/89 |
| b) ATIGEL 20% - 25% | |
System PROTECTED against frost but only partly against corrosion |
FILMAX + Thermakil® ANTIRUST Checks in accordance with STANDARD 8065/89 |
| c) ATIGEL >30% | |
System PROTECTED against frost and corrosion |
Checks in accordance with STANDARD 8065/89 |
On old systems
1) Cleaning: on old systems (also if only partly: ex. new boiler, old pipes) even more so, carry out a pickling, i.e. the removal of oxides and of any existing mud; to this end we advise carrying out the following treatments:
| PROBLEM | PRODUCT |
|---|---|
| Sludge also mixed to weed | ANTINEX + Thermakil® |
| Rust or incoherent black oxide (friable) | ZINCONEX / ZINCONEX-AL + MAG-NEX HP (magnetic filter) |
| Weed and bacteria (e.g. floor systems or expansion vessels / open circuits) | THERMAKIL® WEED CONTROL PRODUCT |
2) Protection: Once the treatment has been carried out protect the systems against corrosion according to cases a), b) or c) above described.
