HVAC solutions to corrosive environments are extremelly important. We all know energy efficiency and reliability are key aspects when it comes to choosing chillers or equipment in general for an HVAC project. The geographical location, though, can be an equally important aspect.
All those installations near the sea coast, or in those settings exposing units to humidity, salt, and other corrosive agents in the atmosphere, need proper protection from those agents.
Corrosion, a relevant aspect in HVAC systems design
Daikin, as world leader in the air conditioning and HVAC sector, considers these aspects, because being able to face these aspects, means being able to ensure the success of HVAC projects. It means ensuring customer satisfaction.
Corrosion is a very common cause of failure in all those HVAC systems in potentially corrosive outdoor environments. Saline coastal environments, large processing facilities like refineries, heavy industrial production areas, auto emissions and power generation facilities, they all release a variety of contaminants that can cause corrosion.
Corrosion can affect heat exchangers and condenser coils, which can fail rapidly. So, to ensure the durability and reliability of the HVAC equipment in those environments, protection from aggressive elements is fundamental.
Let’s take data centers as an example. Those are sensitive facilities, where huge quantities of information is stored. Unplanned down-time in a data center could cost hundreds of thousands of Euros. It goes without saying that a sensitive facility like that, in a potentially corrosive environment, needs special precautions. To ensure continuity of operattions in facilities like these, corrosion control is essential.
Daikin solutions to corrosive environments
Daikin addresses the problem with a few different options, which can guarantee proper protection and ensure units durability and reliability.
Specifically, Daikin offers four different levels of protection against corrosion:
- Blue-coat
- Alucoat
- E-coating
- Blygold treatment
More detailed information on Daikin options
Blue-coat and Alucoat, ensure good protection in mildly corrosive environments, and it is possible to use them respectively on aluminium microchannel condenser coils and copper-aluminium condenser coils.
Cu – Cu CONDENSER COIL option
As an alternative to coatings, Daikin also offers the Cu – Cu CONDENSER COIL option. It is the highest level of corrosion control. With this option, galvanic corrosion doesn’t affect condenser coils, since thay are made of copper only – both tubes and fins. It is a particularly effective option to prevent coastal corrosion and give durability to units’ components in polluted marine environments and Middle East projects. In fact, it is a quite relevant option for all those units operating in the desert.
This option really helps extending the life of a heat exchanger in those situations, but it is not ideal for polluted or industrial applications, since pollutants generally affect copper integrity.
