Heat exchangers coils used in air conditioning and refrigerating systems, are the seat of pollutants (mineral and vegetable dusts, humidity, acid rains, sulphurated or nitrogenous compounds).

These pollutants, major actors of atmospheric corrosion, are extremely harmful for the exchanger’s surfaces (particularly aluminium fins).

The main metal materials, used in the heat exchanger’s manufacturing (aluminium and cuprus alloys, galvanized steel), may corrode.

The corrosion under pollutants deposits, the most frequent, entails the complete deterioration of fins.

Changed into alumina (whitish product), the aluminium fins, for example, becomes breakable without any mechanical property.

To remedy the severe deterioration and extend the heat exchangers fins life, CARLY offers an anti-corrosion treatment - CARLYCOAT.
