Secondary surface (fins) shall be of the plate-fin design using aluminum or copper, with die-formed collars. Fin design to be flat, waffle, or sine-wave in a staggered tube pattern to meet performance requirements. Collars will hold fin spacing at specified density, and cover the entire tube surface. Fins are to be free of oils and oxidation.
Our hot water coils are available in same or opposite-end designs with a wide choice of tube, fin and material options along with multiple circuitry availability. All coils are constructed with plate fins and seamless tube construction.
Casing
Coil casing material shall be galvanized steel at a 16 gauge minimum. Heavier material, stainless steel, copper or aluminum casings are available as required.
Intermediate supports are required every 50” of finned length and shall be bolted to top and bottom casing channels. Coil casings on top and bottom of coils are to have double-flange construction, allowing for vertical stacking of coils.
Tubes
Seamless copper tubes shall be mechanically expanded into plate aluminum or copper fins to form an everlasting bond between primary and secondary surfaces. Tubes are to be mechanically expanded into fins (secondary surface) for maximum heat transfer.
Pressure Testing
Coils shall be tested at 550 psig using dry nitrogen, submerged under water. Dual-operator verification shall determine that all coils are leak-free.
Fluid coils are guaranteed up to a maximum 250° F operating temp, and 300 psig maximum operating pressure.
Connections
Connection is to be sweat type (SWT), MPT or FPT grooved or flanged as required.
