Marley / Sigma 1000/1200 Cooling Tower

igma 1000/1200 towers are ﬁeld-erected, general

purpose crossﬂow wood cooling towers, designed to serve normal air conditioning and refrigeration systems as well as medium sized industrial loads. They evolve from the crossﬂow concept of towers pioneered by Marley in 1938, and incorporate over 65 years of design advancements that our customers have found valuable. Sigma cooling towers represent the current state of the art in this cooling tower category.

This publication not only relates the language to use in describing an appropriate Sigma 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 15 through 29 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 15 through 22 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 maintenanceenhancing 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 23 through 29 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. 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 Marley product line.
