Networks in factories

Most factories have large water networks, whether used for the process (in papermaking for example) or for cooling. Cooling networks are frequently loaded with dust, fine metal particles or other materials, which can be removed by a filter.
For example, Hectron has supplied several plastics factories in which the cooling water is charged with fine plastic particles.
Our filters are also an alternative to magnetic filters: if selecting a sufficiently fine filtration degree, the metal particles of the network are hold. The advantage of our solutions is that the filter will also retain non-metallic materials such as dust.



AG filters are the most used for this application. They are available with very fine filtration degrees what is necessary in several applications.

Advantages :


The AS series filters are also suitable if the network is at very low pressure, for example in the case of air cooling towers.
