FILTRATION SYSTEMS
Series "Bergamo"
Filtration Systems
Bag type Filtration Systems for district heating networks and plants designd in accordance with network nominal flow rates and degree of filtration desired. The system is mounted as "package" with single or twin body for flow rate and maintenance reasons. It comes complete with control, metering and safety devices, as well as fouling meter and transmitter suitable for integration into existing supervisory systems via analog and digital standard and unified signals. The filtration degree can also be varied along operation depending on the fouling observed.
- Nominal flow rate: 35 to 2000 m3 / h.
- Filtering degree: 1 to 1000 μm.
- Pressure drop: <0.3 bar.
- District Heating max Temperature: 135 ° C.
- Max pressure: 25barg
- Certifications: CE / PED.
