The first and most important step in designing a coil is truly understanding the big picture. Plan and spec jobs tend to have more stringent guidelines than other coil applications – but not always. At SFI, we do not approach any coil project with a “cookie cutter” mentality. We creatively use different types of tube and fin designs to best fit your coil requirements. When necessary, we will request further clarification from you, your engineer, or contractor so that we have a clear understanding of the overall system. By doing so, you can be certain that we have selected the right coil for you.
