Cooling and A.C.

The Need
Cooling tower's fillpack and nozzles, as well as heat transfer surfaces are seriously
impaired by suspended material. This may reduce performance by 40 % and increase
energy consumption by 70 %.

The Problem
Suspended particles originate from the following source; airborne, biological growth,
corrosion, carbonate precipition. These form an insulating layer which reduce heat
transfer, Removal of suspended matter will not only ensure less clogging, it will prevent
nucleation which is a floc formation trigger.

The Solution
In large systems ( usually above 420 T.R. ) a sidestream filtration unit will significantly
reduce the problem. Sidestream design is between 6 - 15 % of the full flow and provided
the correct grade is applied, reduces fouling problems, will save up to 40 % excess
energy consumtion, reduce chemical dosing and downtime, as well as maintenance cost.

Performance
Over 150 sidestream system have been operating for more than 6 years. The exact filtration
grade ensures that only particles smaller than a defined size will be recycled in the cooling
loop. Adjustment to the required flow, as well as handy flexibility of filtration grade are
mentioned by customers as an outstanding advantage.

Advantages
All of the advantages of the " grooved disc spin klin system " are fully expressed in the
cooling tower application.

In Addition More Advantages are Highlighted
* Bleeding - Usually backflushing is adjusted to serve as an automatic bleeding outlet.
* Rooftoops - A paramount percentage of cooling facilities are rooftop mounted. In this
case, the lightweight, compact, modular design is extreamely useful.
* Corrosion resistant - Cooling tower water is saline, the advanced technical plastic filters
are immune to corrosion
