Design Factors to Consider While Choosing Steam Coils

Do you want to get the most out of your steam system? You must invest in the best. But how do you know that the coils you buy are worthwhile? Several design factors determine if it is compatible with a particular application and working conditions. This quick blog will help you find the exact fit replacement coil in no time.

What are steam coils?

A steam-generating system can be seen in most industrial and commercial establishments. Here, a steam coil is the central powerhouse of the system. Steam coils are heat exchangers that use steam to raise the air temperature or any other gas. Typically, there are two major types of steam coils:

  • Standard steam coils: A conventional steam coil, often known as a steam coil, is a heat exchanger that warms air or another gas using steam. An inlet header supplies steam to the coil, then distributed throughout a network of tubes. The thermal energy radiating from a steam coil’s fin surface is absorbed by air as it passes over it. After mixing with downstream air, the heated air raises that air’s temperature to the required level for the application.
  • Steam distributing coils: Because of their header construction, steam distributing coils look more complex. They, too, have headers that contain precisely that—a smaller tube encased in a bigger one, giving them the name “tube within a tube” coils. This particular design facilitates even steam distribution from the outer tube to the rest of the coil. It results in more consistent air temperature with better temperature control. 

Major design factors to consider

These factors ensure you get high-performance and well-fitting Trane replacement coils.

  • Air temperature: Inlet airstream and outlet steam temperatures play a vital role. For instance, if air entering is too cold or near the freezing point, it can also freeze the condensate inside the tubes, causing them to burst.
  • Presence of corrosive agents/fumes: One must monitor the presence of corrosives (e.g., chlorides) in the airstream or tube-side stream. It is essential to know that air with high corrosive levels can cause the tubes and heads to deteriorate faster.
  • Casing: Although casing doesn’t affect performance much, it depends on the use case. For example, if the airside pressure drop is relatively high, go for an airtight case to avoid loss or process air.
  • Orientation: Are your power supply and return lines on the top or bottom? One must choose from vertical and horizontal airflow steam coils accordingly.
  • Aspect Ratio: The ratio of the finned height to the finned length. According to most industry experts, the higher the ratio, the more efficient it is.
