en.Wedoany.com Reported - HVAC and heat exchange equipment in New Zealand have long faced corrosion issues caused by marine air, high humidity, and industrial pollutants. Mark Weir, Managing Director of anti-corrosion coating supplier Blygold Oceania, noted that the local market is fully aware of this. Marine air, humidity, and industrial environments accelerate corrosion of coils and heat exchange surfaces. If left untreated, equipment performance will decline and maintenance costs will rise.
Blygold New Zealand applies global anti-corrosion engineering expertise to local conditions, launching a coating system specifically designed for HVAC and heat transfer equipment. The system aims to protect vulnerable materials while maintaining thermal performance, avoiding the creation of new problems while solving existing ones. Aluminum-copper alloy coils commonly used in air-cooled condensers and evaporators are particularly prone to pitting and galvanic corrosion, a process accelerated by salinity in coastal environments, while inland sites may face risks from condensation and chemical exposure.
Blygold's certified coating system forms a thin, uniform barrier on finned and microchannel heat exchangers. Mark Weir emphasized that application is critical, requiring full coverage without affecting airflow or pressure drop. When properly applied, the coating protects assets without disrupting system operation. Anti-corrosion protection is increasingly being considered during the commissioning phase rather than as a retrofit measure. If equipment is treated early, it can extend service life, reduce unplanned maintenance, and delay major capital replacements, becoming an integral part of overall asset strategy. As the construction industry continues to focus on resilience, energy efficiency, and lifecycle performance, anti-corrosion engineering is becoming a practical consideration, centered on long-term protection performance rather than reactive measures after degradation occurs.
