[Guide] – Blue Fin, Gold Fin & Micro Channel Condenser Coils in AC

An air conditioner’s functioning is dependent on the coils. These are the four basic principles of how an air conditioner works.

Blue Fin, Gold Fin & Micro Channel Condenser Coils in AC

Refrigeration cycle:

1- Condensing coil, 2- Expansion valve, 3- Evaporator coil, 4- Compressor


The gas is pressurized and converted to a high-pressure hot liquid.


The liquid flows through coils, where the high-pressure hot liquid is converted to cool liquid by heat release into the atmosphere.

Expanding valve

It converts high-pressure liquids into low-pressure ones.


This happens in the indoor unit. The liquid is low pressure and passes through an evaporation coil. It absorbs heat in the room, then changes to a liquid.

This is how cold air flows out of your air conditioner. The coils are responsible for all this liquid and gas flow. The coils are essential for every air conditioner. Copper coils have been around for as long as air conditioners have existed. The industry moved to aluminum coils due to the high cost of copper.

Both copper and aluminum coils have their advantages and disadvantages. It is important to keep the coils free of corrosion, rust, and other damage. There are many ways to make sure that AC coils work efficiently. The aforementioned technology is one example. Bluefin technology.

Bluefin condensers

Coating the coils with anti-corrosive material can improve their efficiency.

Voltas was the first to utilize this technology to increase the efficiency of AC coils. It was later adopted by prominent AC manufacturers such as Blue Star, Electrolux, and Panasonic.

This technology protects condenser coils against moisture and humidity. This technology is beneficial for people who live in coastal areas with high humidity.

Microchannel condenser coils

This unique technology is used by Samsung to increase the efficiency of AC coils, particularly those located in coastal houses.

The Microchannel condenser coils made of aluminum are available. These flat tubes are made from multiple aluminum sheets and have microchannels that allow the refrigerant to flow.

This setup is unique because it includes flat tubes and aluminum fins that are placed between the tubes. There are also two refrigerant manifolds. This setup does not require two different metals. This eliminates galvanic corrosion.

Samsung calls this technology Multi-Jet technology within its brands.

Hydrophilic Blue Fin

The AC’s life expectancy is affected by corrosion. Heat transfer can be damaged by corrosion. It can also lead to leaks, which can cause loss of refrigerant or damage to the AC. For people who live in coastal areas, this problem is more common than in others. This is due to the presence of salts and ozone in the air.

Regular cleaning of the coils can help prevent salt deposits on the surface. Because of galvanic control, air conditioners with aluminum coils are more susceptible to corrosion than those with copper coils.

Galvanic corrosion when two metals are fused together, this can lead to galvanic corrosion. Galvanic corrosion can be increased by fusing two metals.

Corrosion can also be caused by acids and salt. Corrosion can also be caused by water accumulating on the coils’ surfaces. It is important to remove water from the fins’ surfaces. epoxy can be used to coat the fins.

The epoxy coating prevents water accumulation on the fin surfaces. It is also known as hydrophilic Blue Fin Technology. The coating has low surface tension. Water droplets don’t stick to the surface, so they fall off the surface without any resistance.

The life expectancy of a blue, hydrophilic-coated fin is three times that of aluminum. This is one of the most effective technologies to reduce corrosion and improve the efficiency of air conditioner coils.


Bluefin condenser vs. Gold fin condenser

Bluefin technology is used to protect condenser coils against corrosion and damage. The gold fin technology, which is similar to bluefin technology, sees AC manufacturers apply a golden hydrophilic coat to the condenser tubes.

The Condensers Golden Fin They are superior to the Bluefin condensers because they increase the AC’s heating efficiency by speeding up the defrosting process.

The gold fin condensers don’t rust. This technology offers greater protection for the coils. It is useful in all areas, including coastal areas. The gold fin coating can protect the condenser coils from acidic, salts, and water accumulation. The gold fin coating is 100% non-toxic.

Blue Fin Condenser: Benefits

We have already seen that coils are made from copper and aluminum. Copper tubes are the most common type of air conditioner. Galvanic corrosion can occur if you attach aluminum coils to copper tubes.

The AC coils can also be damaged by other factors like salts, acids, or water droplets. Blue Fin technology is a coating of coils with anticorrosive materials that prevent all forms of corrosion.

Let’s enjoy the Blue Fin condenser.

  • The epoxy coating protects the coils against water droplets and prevents salt deposits from accumulating.
  • Bluefin condensers with hydrophilic properties are less likely to allow water droplets to accumulate. Bluefin condensers improve efficiency and increase the life expectancy of air conditioners.
  • Bluefin technology keeps the dust away and discourages corrosion.
  • Blue Fin technology helps conserve energy because the AC doesn’t have to work as hard.

Anti-corrosive blue fin condensers are essential for it. This will not only increase the efficiency of your AC, but it will also prolong the life of your AC’s lifespan and reduce greenhouse gas emissions.
