Custom Steam Distribution Coils




Model DO – Distributing Steam with Opposite End Connections

Like the other steam coils, distributing steam heating coils are used in a variety of industrial ventilation and process drying applications across almost every industry. As a general rule, coils in this series are selected when the incoming air temperatures are below 40°F and/or the steam supply is modulated for temperature control. Model DO coils can be either 1-or-2-row with connections on opposite ends.

The Distributing Steam coil is often referred to as a ‘no-freeze’ coil. The design features an inner tube, inside the primary tube, that serves two purposes. First, it distributes the steam to the far end of the primary tube where the steam returns and/or condenses in the annular area between the tubes. The second features is that the warm inner tube acts as a heat-trace to keep the condensate in the primary (outer) tube from freezing.
