Marley / Sigma F Series Cooling Tower

he Sigma F Series is a field-erected, crossflow,
T
fiberglass-structure cooling tower designed
to serve normal air conditioning and refrigeration
systems as well as medium sized industrial loads.
Evolving from the crossflow concept of cooling tower
pioneered by Marley in 1938, and incorporating over
65 years of design advancements, the Sigma F Series
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 Sigma F Series 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 12 through 27
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 12 through 19 indicate those paragraphs which
will result in the purchase of a cooling tower which
will not only accomplish the specified thermal
performance, but which will include normal operation
and maintenance-enhancing accessories and features.
It will also incorporate those standard materials which
testing and experience has proven to provide best
results in normal operating conditions.
Pages 20 through 27 provide some 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
Sigma F Series. SPX Cooling Technologies realizes
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
improvement of this product line.

the tower ladder in compliance with OSHA standards. Marley
ladder safety cages are available as an option.
