Coils are manufactured using seamless, deoxidized, heavy
wall, smooth copper tubes. They are mechanically expanded
in self-spaced, full-collared aluminum corrugated plate fins for
permanent bond and maximum heat transfer. Connections
and bends are brazed with high temperature brazing alloy.
The coil is factory leak-tested at 400 psig. All tube sheets are
provided with oversized holes and tubes are supported in
sliding tracks for friction-free assembly and maximum
reliability.
