Watering and micro-irrigation networks require to protect solenoid valves, drip or micro-sprinklers.
The installation of a hydrocyclone or automatic filter (80 – 100 microns) avoids clogging and reduces maintenance compared to cartridge filters. Several Hectron materials are suitable for this application.
SUITABLE PRODUCTS
HYDROCYCLONES HN
Hydrocyclones HN are the most affordable solution if presence of sand. They require manual interventions to drain the tank, but much less frequently than on a cartridge filter. They do not require any minimum pressure.
Advantages :
- Very robust design
PRAGO AUTOMATICFILTERS
Prago filters are suitable for well water with flow rate up to 10 m³/h. They are the most affordable solution among automatic filters.
Advantages :
- Fully automatic
- Online installation on piping
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
- Up to 340 m3/h
