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.
SUITABLE PRODUCTS
AG AUTOMATIC FILTERS
AG series filters are the most used for this application ; they equipp dozens of wastewater treatment plants in France.
Advantages :
- Fully automatic
AS AUTOMATIC FILTERS
AS filters are also suitable , when the filtered water outlet is on a low-pressure network, or at open air.
Advantages :
- Fully automatic
- Work at low pressure.
