Coastal Environments: How Protective Coatings Shield HVAC Systems

While stunning to look at and loads of fun to enjoy, coastal areas are notoriously harsh on HVAC systems. The combination of salty air and high humidity makes rust and corrosion a constant threat. Metal components and coils are exceptionally vulnerable, often showing signs of wear and tear much sooner than similar equipment in inland locations.

Why exactly? Here are some core challenges that your coastal HVAC systems constantly face.

Salt Air = Corrosion

• Salt promotes rapid corrosion and rust on the metal components of HVAC systems.
• Salt particles can decay connections, causing shorts and sensor failures with the electrical components, which means more downtime and service calls.
• Corroded parts reduce heat transfer, increasing energy use and system strain, forcing the equipment to run less efficiently.
• When the wind carries ocean spray inland, possibly several miles from the coast, it settles on equipment, speeding up corrosion and rust.

High Humidity Issues

• Systems work longer and harder to remove humidity, stressing components from early on.
• Humid conditions boost mold growth in ductwork and filters, affecting air quality.
• Moisture damages insulation and causes material breakdown.

Design and Installation Conundrums

• Using corrosion-resistant materials, like marine-grade metals, is essential, but not always done, which can lead to serious equipment problems.
• Units need to be installed away from direct spray and protected with enclosures.
• Proper ventilation and moisture control must be dealt with to help manage coastal humidity.
• Without coastal-rated protection like Heresite’s HereShield, HVAC parts remain vulnerable and decay much faster near the ocean.

Created to Protect

Coastal area HVAC systems certainly present their own challenges. But don’t worry, we have a solution. HereShield water-based air-dry coating is specifically made to protect components in complicated and abrasive marine environments.

HereShield is a low-VOC (volatile organic compound) direct-to-metal coating developed as a high-performance solution for coastal areas. It’s a single-component coating, specially formulated to combat corrosion in marine and saltwater environments, and is typically applied to the internal and external surfaces of HVAC heat exchangers and related equipment.

Check out all the benefits of HereShield:

• Excellent corrosion resistance
• Outstanding UV tolerance and weathering qualities
• Exceptional adhesion to ferrous and non-ferrous metals without complicated pretreatment or primers
• First-rate durability and salt fog performance
• Tremendous film building characteristics
• Splash resistant to acids and inorganic salts
  
  

It’s the Golden Ticket for Marine HVAC Systems

By using HereShield, the life of your coastal equipment is extended by preventing corrosion and rust. The need for service calls, downtime, and early replacements is reduced. It helps maintain peak system efficiency and air quality by safeguarding clean heat transfer surfaces, while minimizing the buildup of dirt and mold. There is NO EQUAL™.
