Islands and beachfront sites
Caribbean projects often place condensing units and chillers within a few hundred metres of the sea, facing the trade winds. Hurricanes carry spray and salt well inland, and strong sunlight ages exposed casings and coil faces.
Two very different coasts
The Atlantic side of the continent is humid and tropical, so coils stay wet for long periods. Parts of the Pacific side are dry, but onshore winds still carry salt, and large mining and processing regions add acid mist and dust.
Long supply lines
Island projects and remote mines are served through transhipment and long inland legs. Coating before shipment, careful packing and a field repair kit for touch-up are worth more here than where local applicators are close at hand.

How are coated units protected through transhipment?
Packing is specified for the extra handling at hub ports, and the packing is photographed as part of the batch record.
Which system suits beachfront resorts?
PG-S1 applied by dip for most beachfront units, and PG-C where units face direct spray.
What about mining sites?
Mining and processing areas with acid mist or dust need the chemical-resistant PG-C system, plus filtration and gentle cleaning.
