Chilled or Hot Water Coils
Depending on how much cooling is needed, chilled water coils are usually manufactured with anywhere between three and twelve rows of tubes. These tubes generally pass through sheets of formed fins, bonded through tube expansion. Commercial Coils can supply water coils with various tube, fin and material options.
Round seamless copper tubes are mechanically expanded into the fin collars of the secondary surface. The mechanical expansion provides a permanent metal-to-metal bond for efficient heat transfer. Tubes are staggered in the direction of airflow and only return bends are used – NO reduced tube wall in the bend radius by using hairpin bends.
Tube Size Options:
5/8″ O.D. x .020″ wall thickness standard with optional wall thickness of (.025) (.035) and (.049). Centerlines are 1.5″ in the tube face and 1.299″ between rows.
1/2″ O.D. x .017″ wall thickness standard with optional wall thickness of (.025). Centerlines are 1.25″ in the tube face and 1.083″ between rows.
