The Sigma Steel is a galvanized steel, field-erected, general purpose crossflow cooling tower, designed to serve normal air conditioning and refrigeration sys- tems as well as medium sized industrial loads. Evolv-

ing from the crossflow concept of towers pioneered by Marley in 1938, and incorporating over 70 years of design advancements, the Sigma Steel 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 Steel cooling tow- er—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 11 thru 25 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 thru 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 mainte- nance-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 thru 27 provide some paragraphs intended to add those features, components, and materials that will customize the tower to meet the user's require- ments.

Space does not permit definition and explanation of all of the possible options that can be applied to the Sigma Steel. 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 better- ment of this Marley product line.
