D-COAT™ Full Corrosion Protection

D-COAT™ is the special coating that can reduce water residuals and stop oxidation which is the main reason why coils corrode. D-COAT™ has anti-microbial additives that can prevent the growth of bacteria and fungi. 

D-COAT™ treatments are designed for use on commercial air conditioning coils, refrigeration, industrial coils, transport and other air conditioning equipment: coils, fins, tubes and all internal metal surfaces.

What Causes Corrosion?

Simple copper and aluminum heat exchangers achieve excellent heat exchange properties but they are dissimilar metals and will corrode at the point where copper meets aluminium. This corrosion is called 'galvanic corrosion' which can be rapid and pre-coated fins do not eliminate this risk. Substantial efficiency losses will occur.

D-COAT™ provide a super- thin 6-9 micron layer to prevent this from happening. This stops the corrosion and doubles (or more) the life of the coil

Fin Protection

When applied to new coils the fin protection is excellent and can double the life of ant heat exchangers. Protection from extreme pollutants is assured using D-COAT™ coatings.

Heat exchangers are crucial for the creation of comfortable living environments. It has been well documented that heat exchange makes up to 60% of buildings energy consumption. Inefficient poorly maintained heat exchangers can add thousands of dollars to a buildings monthly electricity bill.

The two main issues affecting the efficiency of heat exchangers are:

  • Corrosion due the environment such as salt and pollution
  • Fouling of the heat exchange unit with contamination such as dirt and biofilm

The benefits of D-COAT™ coatings:

For Condensers

  • Surfaces remain free from surface corrosion retaining heat exchange capacity
  • The coating is smooth and resists build up of dirt and oil from pollution
  • The surface remains dry and resists chemical attack from salt, sulphur and other environmental chemicals

For Evaporators

  • Condensate water faster and reduce water retention increasing the heat exchange capacity and increasing airflow
  • The super hydrophobic surface is self cleaning
  • Surface remain free of biofilm and mold due to the built in anti microbial activity of the coating.
