Cooling Water

Cooling water

Filtration degree between 25 and 100 microns.

The water used in these circuits are usually polluted not only with residual material originating from the production cycle, but also (in case of cooling towers) with particles present in the air used for the cooling of the water.
The polluting material can be sand, dust, organic or inorganic residue. These pollutants dispersed in the water can cause damage to the piping or the factory facilities, by clogging them and causing a decrease in the efficiency of the cooling process.
In this case the filters we use are the AVC model with a filtration degree between 25 and 100 microns. The filter tissue is also functionalized with the so called OilRepellent™ technology, that retains the oil and grease deriving from the production cycle. Only when the content of suspended solids in the water is very high, also AHC filters are used (centrifugal separators) as a first-step filtration.

Application schemes

River / lake waters can contain a high SST content,
therefore in the first stage an ABV filter (200 ÷ 100µm) is generally used, capable of evacuating even large solidids without the need to use a prefilter.
In the case of taking water directly from the sea, there may be many SSTs in the water.
the most suitable filter is the ABV model (200 ÷ 100µm) capable of separating large quantities of contaminants, even large ones.
The band filter (ABF) can be used as a polishing unit after sand filtration.
In these cases the filter can ensure filtration up to 15µm.
