FLOWLIMIT

FLOWADAPT benefits from the advantages of AUTOADAPT, along with the availability to set a maximum flow limit with FLOWLIMIT. Once the desired maximum flow is set, a remarkable energy saving can be achieved. The MAGNA3 continuously monitors the flow rate ensuring that it is not exceeded. This will save the cost of a separate balancing valve.

Intelligent Interface – Monitoring

MAGNA3 comes with a monitoring function, which makes it possible to keep track of the heat energy distribution and consumption within a system. This avoids excessive energy bills caused by system imbalances.

The heat energy meter has an accuracy between +/-1% and +/-10% and makes installing a separate energy metering device within your system superfluous.

Temperature input from return pipe

Intelligent Interface – Work Log

Every duty point and the operational conditions are tracked and stored in the pump.

The 3D work log and duty over time curve, provide instant overviews of historical pump performance and operational conditions.

The perfect tools for pump optimization, replacement and troubleshooting.
