Ultra Low-Noise Fan

1.4Replace paragraph 6.1 with the fol- lowing: Fan(s) shall be propeller-type, incorporating wide-chord forward- swept FRP blades and galvanized hubs. Blades shall be individually adjustable. Maximum fan tip speed shall be 51 m/s. Fan(s) shall be driven through a right angle, industrial duty, oil lubricated, geared speed reducer that requires no oil changes for the first five (5) years of operation. The gearbox bearings shall be rated at an L10A ser- vice life of 100,000 hours or greater. Available on Models NC8302 through NC8312.

Single Hot Water Inlet Connection per Cell:

8.2Replace this paragraph with the following: Each cell of the tower shall include a single hot water inlet connection located as shown on the plans. An internal system of piping shall deliver water equally to the dis- tribution basins without the need for balancing valves. This internal piping system shall require no scheduled maintenance, and shall be located such that it does not interfere with normal maintenance access. The internal pip- ing must extend to the tower exterior. Removable, interchangeable polypro- pylene nozzles installed in the floor of these basins shall provide full coverage of the fill by gravity flow.

Air Inlet Screens:

9.1Add the following paragraph to the Casing, Fan Deck and Fan Guard sec- tion: The air inlet faces of the tower shall be covered by 1" mesh hot-dipped galvanized welded wire screens. Screens shall be secured to removable galvanized U-edge frames.

High Wind Load/Seismic Designs:

4.1Replace this paragraph with the fol- lowing: The tower structure, anchor- age and all its components shall

be designed by licensed structural engineers per the international build- ing code to withstand a wind load of

■For more severe cases requiring the lowest possible fan sound levels the Marley “Ultra Low-Noise” fan option is now available on all but the NC8301 NC Class models. Tower height may increase slightly—obtain current sales drawings from your Marley sales representative for accu- rate dimensions. If your requirement calls for inlet and outlet attenu- ation, you might consider the Ultra Low-Noise fan in lieu of attenua- tion. Outlet attenuators are not available with the Ultra Low-Noise Fan option.

■This option reduces what might otherwise be a complex hot water piping layout to a simple, single connection per cell. It also avoids an unsightly (perhaps unsafe) maze of pipe exposed above the top deck of the tower.

The single inlet connection can be located either in the tower's endwall casing, or below the cold water basin. The endwall entry point is suit- able for single-cell towers, and for those that might be installed in groups of two cells each. Bottom inlet piping lends itself to close- spaced, multicell installations and to those situations where it is appro- priate to keep all pipework below the level of the tower.

Be sure to specify that the internal pipe extends to the tower exterior panel, either the casing panel or collection basin floor. Some manufac- turers require the contractor to complete the internal piping adding to your cost.

■In wooded or windy areas, these screens help to keep leaves or blowing debris out of the cool- ing tower and circulating water system.

■High wind load designs greater than 30 psf are available up to 100 psf.

It is important to consult

the local code official for actual requirements. Some manufacturers will claim their tower is capable but have never had the design reviewed by a licensed structural expert. Not requiring expert review for high wind and seismic regions is dangerous to you and the public.
