Get Ready for Steam Coil Season

Now that we are nearing the end of summer, steam coils become a focal point to ensure you and your customers are ready for this years upcoming winter. Below we have some tips to determine which type of steam coil you have along with different options that help us give you the best estimate possible.
Standard steam coil can come with both same end connections and opposite end connections.

Tube size options with steam coils will always be 5/8” or 1”and can be copper, carbon steel or stainless steel are some of the most common tube materials.
It is important to know the steam pressure because it will determine the tube thickness/material that is needed to handle that amount of steam pressure.
Steam Distribution coils can also come with connection on the same or opposite ends. But the big difference is the way the coil is constructed. Steam distribution coils have a tube in tube construction and the U bends on the back aren’t U-bends like most standard coils. Steam enters in the supply of the coils and is baffled to the inner tubes where there are jets that spray the steam like a nozzle to the outer tube. The steam condensates and gravity helps the condensate flow back where it is baffled to the return outlet of the coil and the condensate flows to the trap. Making sure that your steam coil is properly pitched is critical to avoid problems. Pitched in casing design is something we manufacture and it places the fin pack at a perfect angle within a square casing making for ease of installation and smooth operation for your steam distribution coil.

Below is a chart that helps determine tube size/materials:
Construction Considerations
5/8” coils over 72” FL (suggest a dual supply)
1” coil over 120” FL (suggest a dual supply)
SD coils over 48” FH (suggest extra supply connection on header)

Tube Wall / Material Considerations
Steam (PSIG)
