Standard Steam Coils

Model S – Standard Steam Coil with Opposite End Connections

Standard steam coils, specifically the Model S, are configured with connections on opposite ends of the coil. This type of custom steam heating coil allows steam to enter the supply header where it hits a plate to distribute steam to all tubes. The steam then condenses along the length of the tube and drains out the return header.

Standard steam coils are used in a variety of industrial ventilation and process drying applications across various industries. As a general rule, coils in this series are selected when the incoming air temperatures are above 40°F and the steam supply is maintained at a relatively constant pressure.

Custom Steam Heating Coils

Type S steam heating coils are available as both one-row and two-row deep coils with the steam feed connection on one end and the condensate return connection on the opposite end. We also ensure that this model is TIG welded tube-side during construction, and we’re able to provide ASME ‘U’ stamp or CRN construction.
