7.0Fill, Louvers and Drift Eliminators:

31

7.1

Fill shall be cross-corrugated,

Fill modules can be removed for inspection and cleaning in accor-

 

counterflow film type, thermoformed

dance with local anti legioinella guidelines.

 

from 0.40mm thick PVC. Fill shall

Drift rate varies with design water loading and air rate, as well as

 

be assembled into packs for ease of

 

removal and cleaning. Fill shall be sup-

drift eliminator depth and number of directional changes. The indi-

 

ported on channel sections supported

cated rate of 0.001% is easily achievable without premium cost. If a

 

from the tower structure and have a

lower rate is required, please discuss with your Marley sales repre-

 

flame spread rating less than 25. Drift

sentative.

 

eliminators shall be PVC with a mini-

 

 

mum of three changes in air direction,

 

 

and shall limit drift losses to no more

 

 

than 0.001% of the design water flow

 

 

rate.

 

7.2Air inlet louvers shall be a minimum of

127mm air travel, triple pass PVC to prevent water splashout and eliminate sunlight from entering the collection basin. For ease of service and long life of louvers, PVC louvers shall be enclosed in a removable frame that attaches to the air inlet without tools. Louvers with less than three changes in air direction are unacceptable.

8.0Hot Water Distribution System:

8.1

A pressured spray system shall dis-

The combination of PVC piping and polypropylene nozzles is very

 

tribute water evenly over the fill. The

resistant to the build-up of scale and slime.

 

branch arms shall be corrosion resis-

 

 

tant PVC with polypropylene spray noz-

 

 

zles attached to the branch arms with

 

 

a rubber socket connection for ease of

 

 

removal and cleaning. To ensure proper

 

 

spray system operation, nozzles shall

 

 

seat in branch arms without regard for

 

 

direction or alignment.

 

9.0Casing and Fan Guard:

9.1The casing shall be heavy gauge EN10142:2000 grade Z600 galvanized steel and shall be capable of with- standing the loads described in para- graph 4.1. Casing panels shall encase the fill on all four sides of the tower. The top of the fan cylinder shall be equipped with a conical, non-sagging, removable fan guard, fabricated of welded 5/16" and 7 gauge rods, and hot dip galvanized after fabrication.
