SDC Steam Distributing Coil
For use when entering air temps are below 40F degs. Most coils offered with pitched casing so condensate does not lay in the coil. Available in both 5/8” OD tubes and 1” OD tubes.
Also known as "non-freeze", steam distributing coils are a different coil than standard steam because they are built with a tube within a tube construction.
The steam on the inner tube keeps the condensate in the outer tube from freezing.
The purpose of the original coil design was to distribute the steam evenly along the length of the coil and to eliminate and dead spots on the coil.
