Specification Value

designed for 2.4kPa live load or a 91kg concentrated load. Guardrails, where specified, shall be capable of with- standing a 890N concentrated live load in any direction, and shall be designed in accordance with OSHA guidelines.

5.0Construction:

5.1Except where otherwise specified, all components of the cooling tower shall be fabricated of heavy-gauge, series 300 stainless steel. The tower shall be capable of withstanding water having a chloride content (NaCl) up to 750 mg/L; a sulfate content (SO4) up to 1200 mg/L; a calcium content (CaCO3) up to 800 ppm; silica (SiO2) up to 150 mg/L; and design hot water temperatures up to 52°C. The circulating water shall contain no oil, grease, fatty acids, or organic solvents.

5.2The specifications, as written, are intended to indicate those materials that will be capable of withstanding the above water quality in continuing service, as well as the loads described in paragraph 4.1. They are to be regard- ed as minimum requirements. Where component materials peculiar to indi- vidual tower designs are not specified, the manufacturers shall take the above water quality and load carrying capabili- ties into account in the selection of their materials of manufacture.

shipped, handled, hoisted—and ultimately operated in a normal cooling tower environment. Most NC Class models will withstand significantly higher wind and seismic loads. If your geographic location dictates higher wind load or seismic load values, please make the appropriate changes, after discussion with your Marley sales representative.

Note: Some countries and states (Florida) require structure not anchor- age. Check with you local officials.

1.44k/Pa windload, .3g seismic load—applicable for most applications but consult the local code official for actual requirements.

2.4kPa live load, 890N concentrated load—ensures the tower can be safely accessed for routine maintenance when a guardrail is installed as well ensuring the end user complies with government safety laws.

■For pure resistance to corrosion—coupled with the capability to meet stringent fire and building codes—there is no substitute for stainless steel! No paints or electrostatically-applied coatings, however exotic they may be, can match stainless steel's ability to withstand adverse operating conditions.

Although SPX Cooling Technologies makes use of many structural FRP components in various other product lines, they are held to a relative minimum in the NC Class Stainless line. This is to assure that there will be no question as to the structural integrity, fire resistance, and life expectancy in the mind of the owner.

Except for those unusual operating situations where the circulating water may be so laden with suspended solids, algae, fatty acids, prod- uct fibers, active organisms reflected in BOD, and the like that plug- ging of film type fill is a probability, the NC Class Stainless is relatively immune to poor water quality. Where such conditions do exist, how- ever, thought should be given to the prevention of such carryover—or to the use of a Marley splash-fill product. Please discuss your situation with your Marley sales representative.
