Hydronic duct heating and cooling coils use hot or chilled water to produce supplementary warm or cool air. They're used in both replacement and new construction applications in large commercial buildings. Coils in a flanged casing mount in air-handling units or to ductwork, while coils in a slip and drive casing can be directly connected to the ductwork. Coil connections are 3/4" MPT copper tubing. The coils have aluminum fins in a galvanized steel casing.
