16-19: Methodology To Validate Sound Levels Of Factory Assembled TowersThe Cooling Technology Institute has a very successful, long standing program for thermal capability certification of factory assembled towers, but this type of confidence or 3rd party validation for published sound levels does not exist within the industry. The paper discusses an approach taken, with its successes and challenges, to acquire a sound data set for an entire crossflow model line that accurately reflects sound emission of all models

In accordance with these codes

it is important to operate at a speed sufficiently lower than the drive shaft's natural frequency to prevent destructive vibration

in some cases

but these devices are not an unmixed blessing

The thermal performance of a cooling tower can be regulated by varying fan power

and the somewhat belated realization that feed of a cationic polymer ahead of membrane systems is typically not a good idea

whether processed from virgin or reground material

A performance test of modified tower is to be conducted in June-July

safety compliance

This subject is important because of the increasing use of bromine chemistry for industrial water treatment

the chemistry of the cooling water does not support the growth of Legionella pneumophila

labor-intensive task involving the microscopic examination and statistical extrapolation
