Applications
Steam distributing coils are commonly used for supply pre-heat, outside air tempering, and modulating steam applications.
Capabilities Overview
Features include choice of supply from both ends of the coil, and supply/return connections on the same or opposite ends of the coil. Pitched casings insure condensate removal and performance reliability for vertical or horizontal air flow.
How Steam Coils Work
Due to their tube-within-tube design, steam distributing coils provide a level of protection against freezing in low-temp applications. The inner tube ensure live steam is distributed across the full length of the coil, maintaining consistent outer tube temperature under all conditions.
Steam enters through the supply connection and into the internal distribution tubes. Directional dispersion holes meter the flow of steam from inside the distribution tube into the annular region between the tubes. The steam then condenses and flows into the return header. Steam Distributing coils maintain a constant temperature rise across the face of the coil while facilitating condensate drainage.
While often referred to as “non-freeze,” steam distributing coils should be considered freeze-resistant—no coil is completely immune to freezing under the right conditions, but this design helps mitigate that risk.
