Energy recovery coating

The thin gauge aluminum coatings are supportive of heating, ventilation and air conditioning applications. Hydrophilic and hydrophobic coatings are designed to thrive in your environment — whether you need maximum moisture dispersion or extreme water repellency.

Hydrophilic

Hydrophilic coatings are used in HVAC systems, particularly on heat exchangers, to improve performance and longevity. These coatings are water-attracting and help manage condensation by promoting efficient drainage, reducing water carryover, diminishing the risk of mold and bacterial growth and enhancing heat transfer. They also offer corrosion protection, especially in humid or coastal environments.

In heat pumps, where the coils can act as both evaporators and condensers, the hydrophilic coating helps manage condensation in both modes. Microchannel heat exchangers have compact designs and increases the need for efficient condensate management.

Hydrophobic

Hydrophobic coatings for HVAC systems are designed to repel water, preventing it from adhering to surfaces like coils and potentially causing corrosion or reduced efficiency. These coatings create a high contact angle with water, causing droplets to bead up and roll off instead of spreading. The beading and runoff effect can lead to a self-cleaning mechanism, where water droplets carry away dust and other contaminants, keeping the coils cleaner for longer. This can lead to several benefits, including improved heat transfer, reduced corrosion, minimized repair cost and extended equipment lifespan.
