Hydrun Filter Station is a fully automatic filter station for the hydronic system, designed to ensure clean system fluid through continuous filtration of contaminants and magnetite.
The Filter Station operates on a partial flow and continuously draws in system fluid via its powerful and robust circulation pump.
The unit is equipped with a display showing how full the filter is. An alarm is triggered when the filter starts to get full (custom threshold), enabling proactive filter replacement.
When the filter is full, a new alarm is triggered and the pump stops.
Alarm functions ensure continuous filtration, while stopping the pump when the filter is full saves energy and extends the service life of the unit.
Proactive alarm for upcoming filter replacement. Alarm and pump stop when the filter is full.
Easily choose between continuous or scheduled filtration (day of the week and start time).
Clear connection logic and preset values reduce time on site.
Modbus TCP, RTU, and BACnet for alarms, status, and logging directly to the BMS/DDC as standard.
Use the same system connection as the degasser and save two extra connections.
Save energy by continuously reducing the amount of dirt and magnetite in the system.
