Anti-Corrosive Coatings

DOLPHIN offers a number of Protective Coatings to enhance the life of its coils including Condensers & Evaporators which includes,

  • Thermoguard (Silver)
  • Heresite (Brown)
  • Hereshield (Gray)
  • Hydrophilic (Blue)
 

These coatings have a High Durability and have Protective Factors to deal with the severe Gulf Region Atmospheric changes, on shore as well as offshore. Each of these coatings carries a warranty of 2-7 years.

Air conditioning can consume 60% of the electricity in an average office building, if coils are not protected from corrosive elements, operating costs will accumulate rapidly.

Thermoguard Coatings:
 

Dolphin provides one of the best anti-corrosive and polyurethane coatings available. Thermoguard coatings offer exceptional UV resistance and durability, using VOC-free technology for superior performance.

Thermoguard (T.G. Coating) offers a wide range of product applications to increase the corrosion resistance of HVAC & R units and other coils. The capacity of a heat exchanger originates from the absorption or rejection of heat from the aluminium / copper finned surfaces.
 
The coolant travels through the copper or other tubes transporting the heat throughout the system. When corrosion is present, it deteriorates the finned surface area and/or the bonding between aluminium fins and copper tubes (known as galvanic corrosion), therefore the capacity of the heat exchanger can deteriorate substantially.

Some advantages of T.G coatings are,

  • Thermoguard (Fin Guard Silver): Protective coating shields HVAC-R coils from highly corrosive environments.
  • Salt Spray Tested: Withstands up to 11,000 hours of salt spray testing, meeting ASTM B 117 standards.
  • Energy Savings and Sustainability: Proven to reduce CO: emissions, enhancing energy efficiency and sustainability.
  • Long-Lasting Protection: Extends coil lifespan by providing a robust defence against harsh environments.
  • Complete Surface Coverage: Complete penetration and sealing of the heat exchanger surface, including the critical fin/tube interface, for thorough protection.
  • Flexible Urethane Base: Designed to expand and contract with temperature changes, maintaining heat transfer efficiency and structural integrity.
Heresite Coatings:
 

Heresite air-drying phenolic series coatings are formulated for application by brush, spray, or roller. These coatings are renowned for their:

  • Excellent durability and adhesion
  • Effective protection against splashes, spills, and fumes
  • Resistance to harsh climates and corrosive fumes

 

Suitable for a variety of applications, Heresite coatings ensure no significant efficiency loss and are ideal for:

  • Air conditioning and refrigeration coils
  • Agricultural Implements
  • Chemical plants
  • Sewage disposal systems
  • Textile industries
  • Ventilation systems
HereShield Coatings:
 
HereShield WB 506 (Gray) is a high-performance water-based coating designed for standard protection needs. Its advanced formula ensures durability, corrosion resistance, and environmental safety, making it an ideal choice for industrial and commercial applications. The water-based composition provides low VOC emissions, ensuring a safer and eco-friendly coating solution. With its strong adhesion and long-lasting protective barrier, HereShield WB 506 effectively shields surfaces from wear and environmental damage, extending the lifespan of the coated materials.
Hydrophilic Coated Finstock:
 
It is engineered for optimal heat transfer efficiency in air conditioning and refrigeration systems. Its 100% surface coverage ensures a uniform coating, providing excellent water drainage and preventing water droplet accumulation, which enhances performance and reduces airflow resistance. The coating forms a strong, 100% bonded layer, ensuring long-lasting durability without peeling or degradation. Additionally, the advanced formulation maintains its original colour, preserving the aesthetic and functional integrity of the finstock over time. This hydrophilic coating significantly improves system efficiency, corrosion resistance, and overall lifespan.
