Blygold supports HVAC performance in harsh environments
Throughout New Zealand, corrosion remains a constant and costly challenge, particularly for HVAC and heat exchange systems exposed to coastal air, humidity, and industrial pollutants.
Left untreated, corrosion doesn’t just damage equipment, it directly impacts performance, increases maintenance demands, and shortens asset lifespan.
“Blygold New Zealand brings 50 years of global corrosion engineering expertise to local projects, delivering specialised coating systems designed for HVAC and heat transfer equipment operating in harsh conditions. These solutions are engineered to protect critical components while maintaining optimal thermal performance,” says company owner, Xavier Castelltort.
He explains that aluminium and copper alloy coils, commonly used in air-cooled condensers and evaporators, are highly vulnerable to corrosion.
“Coastal environments accelerate deterioration through airborne salt, while inland conditions introduce moisture, condensation, and chemical exposure. Blygold’s proven coating systems create a thin, uniform protective barrier, safeguarding finned and microchannel heat exchangers without compromising airflow, efficiency, or pressure drop,” says Castelltort.
“There is a clear shift across the construction and facilities sector towards proactive asset protection. Increasingly, corrosion protection is being specified at the commissioning stage rather than treated as a reactive measure. Early intervention can significantly extend equipment life, reduce costly downtime, and delay major capital replacement.”
As New Zealand continues to prioritise resilient, energy-efficient buildings with strong whole-of-life performance, Castelltort says corrosion protection is no longer an afterthought but a “strategic investment in long-term asset value”.
