Special Anticorrosive Coatings

At DOLPHIN, we provide advanced protective coatings for coils, including Condensers and Evaporators, designed to extend their lifespan and optimize performance. Our specialized coatings, Thermoguard and Heresite, are engineered to withstand the harsh environmental conditions of the Gulf region, whether onshore or offshore, and come with warranties ranging from 2 to 7 years.

Anticorrosive coatings protect surfaces from corrosion, enhancing durability and extending the lifespan of equipment in harsh environments. These coatings are essential for industries like HVAC, marine, and manufacturing to prevent damage and reduce maintenance costs.

Why Protective Coatings are Essential

Air conditioning systems can account for up to 60% of electricity consumption in a typical office building. Unprotected coils exposed to corrosive elements not only degrade faster but also lead to increased operating costs due to inefficiency and frequent maintenance. Applying protective coatings helps mitigate these issues by:

  • Preventing Corrosion: Protecting coils from atmospheric and chemical exposure.
  • Enhancing Efficiency: Maintaining heat transfer capacity and minimizing energy loss.
  • Reducing Maintenance: Extending coil lifespan and reducing the frequency of cleaning and repairs.
Thermoguard (T.G. Coating)

Thermoguard is a high-performance coating designed to increase the corrosion resistance of HVAC&R units and other heat exchange systems. It protects the critical components of a heat exchanger, such as the aluminum fins and copper tubes, from deterioration caused by environmental and chemical factors.

How Corrosion Impacts Performance:

  • Corrosion reduces the surface area of aluminum fins, decreasing the system’s ability to absorb or reject heat.
  • Galvanic corrosion can weaken the bond between aluminum fins and copper tubes, significantly compromising the heat exchanger’s capacity.
    Thermoguard’s advanced formulation addresses these challenges effectively.
 Key Advantages of Thermoguard Coating:
  1. Superior Corrosion Resistance:
    • Prevents galvanic corrosion, microbial growth, and chemical degradation.
    • Suitable for a wide range of environmental conditions, from industrial zones to coastal areas.
  2. Enhanced Durability:
    • Resistant to temperature variations from -30°C to +180°C, ensuring consistent performance.
    • Reduces dirt adhesion, making the coils easier to clean.
  3. Health and Environmental Benefits:
    • Incorporates a non-toxic micro-biocide, preventing mold and fungal growth.
    • Eliminates bad odors caused by microbial contamination.
  4. Operational Efficiency:
    • Minimal impact on the system’s heat transfer coefficient (K-Value) and pressure drop (ΔP).
    • Improves droplet shedding, reducing the need for frequent cleaning and lowering maintenance costs.
Heresite Coating

Heresite is another high-durability coating solution designed for extreme environments. It provides robust protection against the corrosive effects of salt, humidity, and industrial pollutants, making it an excellent choice for offshore and heavy-duty applications.
