Cooling Towers / cooling Water
Full Stream Filtration

Industries - Pharmaceuticals, Machines, Metallurgy, Moulding, Food & Beverage,
Commercial Cooling and A.C.

The Need
The same as in large cooling towers. In addition some of the systems may be of the
open cooling water loop nature; i..e. more dirt evolving from product direct cooling
and nozzle protection is usually involved as well.

The Problem
Suspended contaminations reduce the effciency of fillpack and cooling spray nozzles.
The nozzles are frequently blocked and the heat exchanger rate is reduced.

The Solution.
Full stream filtration, predominantly at cooling capacities up to 420 T.R. A carefully
selected and accurately designed filtration system that ia able to solve nozzle clogging
as well as reduce chemical dosing expenses by 40 %

Performance
Over 70 systems have been serving the above mentioned industrial sectors for the past
7 years. Systems are always designed with a by pass and indicator. Compact system to
adjust to confined space. The flush volume serves as bleeding and can also be recirculated.
Air aided flushing is applied when pressure is low and when fine filtration is needed.

Advantages
Sames as with sidestream systems, in addition:
- Compact modular system for confined spaces.
- Air aided flushing to further diminish flush volume < 0.2 % of flow.
- Fine guranteed filtration grade.
- Profound acquaintance with customer's needs.

A.F.S. Industrial Division Capabilities in Addition to Design and Supply
- Sidestream planning recommendation - sidestream volume, positioning, filtration grade
intake and return locations, computerized planning.
- Engery monitoring - by simple temperature parameters the end user can receive his:
" Actual V.S. optimal designed energy consumption " and check cooling system operation
as well as filtration system performance.
- Intergration with bilogical growth retardants, scale and corrosion prevention.
- Chryptosphoridium - there is no media which is regarded as a breeding ground for this
pathogenic oocyst.
