Marley / NC Class Stainless Cooling Tower /
3
NC Class Stainless Steel towers are factory
assembled, crossflow cooling towers, designed to
serve air conditioning and refrigeration systems as well
as light to medium industrial process loads on clean
water. They evolve from a factory-assembled concept
of towers pioneered by Marley some 50 years ago, and
incorporate all of the design advancements that our
customers have found valuable. The NC Class has been
designed specifically for sound control and tonnage
density and represents the current state of the art in
this cooling tower category.
This booklet not only relates the language to use in
describing an appropriate NC Class cooling tower—
but also defines why certain items and features are
important enough to specify with the intention of
insisting upon compliance by all bidders. The left-hand
column of pages 4 thru 22 provides appropriate text for
the various specification paragraphs, whereas the right
hand column comments on the meaning of the subject
matter and explains its value.
Pages 4 thru 10 indicate those paragraphs which will
result in the purchase of a basic cooling tower—one
that accomplishes the specified thermal performance,
but which will lack many operation—and maintenance-
enhancing accessories and features that are usually
desired by those persons who are responsible for the
continued and continuing operation of the system of
which the tower is part. It will also incorporate those
standard materials which testing and experience has
proven to provide acceptable longevity in normal
operating conditions.
Pages 11 thru 22 provide paragraphs intended to add
those features, components and materials that will
customize the tower to meet the user's requirements.
Space does not permit definition and explanation of all
of the possible options that can be applied to the
NC Class. We realize that you, the purchaser, must
be happy with the tower's characteristics, and we are
prepared to provide—or provide for—any reasonable
enhancement that you are willing to define and
purchase. Your needs will become part of the
continuing evolution of this Marley product line.
