Gold Fin anti-corrosion treatment
15 days salty fog exposure test
The heating exchanger of outdoor
units undergoes a special treatment
called Gold Fin which gives more
strength to corrosion, if compare
to that of conventional units, also
protecting its integrity and services
during the time.
After 15 days
Gold Fin protected Aluminium
Gold Fin, no corrosion traces
After 15 days
