Primary Surface
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.
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.
- 3/8″ O.D. x .016″ wall thickness standard with optional wall thickness up to (.035). Centerlines are 1″ in the tube face and .866″ between rows.
- Rows available are 1, 2, 3, 4, 5, 6, 8, 10 and 12.
Secondary Surface:
Corrugated, flat and sine plate type fin that is die-formed. Fin collars are full-drawn to provide accurate control of fin spacing and maximum contact with tubes.
Fin Material Options:
- 5/8″ tubes comes standard with aluminum fin .006″ and .008″ thick with optional (.010). Optional copper fin thicknesses available are (.006) (.008) and (.010). Fins per inch available 4 through 14.
- 1/2″ tubes comes standard with aluminum fin .006″ thick with optional thicknesses available. Copper fin thicknesses available to .008″ and 0.10″.
- 3/8″ tubes comes standard with aluminum fin .006″ thick with optional thicknesses available. Copper fin thicknesses available start at .0045″ and .008″.
- Fins per inch available 6 through 20. Other fin types available: Lance and Louvered.
Also Available: Intermediate headers for full “drainability”.
Headers:
Seamless copper with die-formed holes that provide a parallel surface to the coil tube for strong brazing joints. Standard 1/8″ brass female pipe thread (FPT) vent and drain with optional (1/4) and (3/8). All circuiting is designed to gravity-drain with the coil mounted vertically and tubes running horizontally.
Connections:
Red Brass Schedule 40 (MPT) is standard with optional Carbon Steel, Copper, Copper Nickel and Stainless Steel available. Options for FPT also available.
Casing:
Using 16-gauge minimum thickness material, flanges are die-formed to permit easy stacking and mounting. Intermediate tube supports are supplied on coils over 44″ fin length with an additional support every 42″ multiple thereafter.
Casing Material Options:
Galvanized steel standard with optional stainless, aluminum and copper.
Testing & Performance:
All coil assemblies are leak tested under water at 350 PSIG air. Standard construction is suitable for 250 PSIG and up to 300 degrees F.
