FINS

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.

tubes220x200

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.

headers236x200

HEADERS

Headers (manifolds), if required, shall be constructed of a minimum .060” wall seamless copper. Die-formed copper end caps are brazed on the inside of the headers, and rounded so as to prevent excessive pressure drop. (Unless spun-closed — for sizes up to 1-3/8”) All coils shall be provided with 1/4” vents and drains.

connections255x200

CONNECTIONS

Connection is to be sweat type (SWT), MPT or FPT Grooved or flanged as required.

casing308x200

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 42” 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.

psi-gauge207x200

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 300° F operating temp, and 250 psig maximum operating pressure.

ahri-certified-logo-274
