Equipment and Coil Types
Where each type of coil corrodes, and how it is protected.
Copper Tube, Aluminium Fin Coil ProtectionWhy copper-tube, aluminium-fin coils corrode at the fin-to-tube joint, and which coating system to specify for coastal, industrial and wastewater sites.
Microchannel Coil Corrosion ProtectionWhy all-aluminium microchannel coils fail fast in salt air, whether they can be coated, and which thin-film system keeps louvered fins open.
Condenser Coil Anti-Corrosion CoatingWhere outdoor condenser coils corrode first, which coating to specify for coastal, desert, industrial and wastewater sites, and how it is applied.
Evaporator Coil CoatingWhy indoor evaporator coils corrode under constant condensate, when coating them is worth it, and which system suits humid and fresh-air duty.
VRF and Split Outdoor Unit ProtectionHow VRF and split outdoor units bought from China are protected before export — coil removed and dipped, or the complete unit masked and coated.
Air-Cooled Chiller Coil ProtectionProtecting the large condenser coil banks of air-cooled chillers — size limits for dipping, when spray is used, and which system to specify.
Heat Pump Coil ProtectionWhy heat pump outdoor coils face defrost cycling as well as salt, and how to choose a coating that survives repeated wetting and temperature swings.
Dry Cooler Coil CoatingProtecting dry cooler and fluid cooler coils for data centres and process cooling — coastal and industrial sites, and coils wetted by adiabatic pre-cooling.
AHU Coil CoatingWhen air handling unit coils need coating — fresh-air duty near the sea, humid and polluted intake air, and pool or process spaces — and which system fits.
Cold Room and Refrigeration Evaporator CoatingWhy cold room and food-process evaporators corrode — frost and defrost cycles, washdown chemicals and food acids — and what a coating must survive.
Generator and Industrial Radiator CoatingProtecting generator and industrial radiators at coastal, desert and remote sites — aluminium and copper-brass cores, and which coating fits each.
