MAGNA3 D is an energy-efficient intelligent wet rotor electronic circulator. It is a highly advanced circulation pump with intelligent features to ensure that the system always provides the best possible comfort and most efficient operation.

 

MAGNA3 D features two pump heads that communicate wirelessly. They can operate in alternating mode, in which one pump runs simultaneously; in cascade mode, in which the second pump head contributes when needed; and finally, in reserve mode, in which one pump is 100 percent redundant. This intelligent, wireless communication and multi-pump functionality ensures peace of mind and continuous supply, ideal for commercial buildings where downtime is not tolerated.

 

Built-in thermal energy meter:

• This feature monitors the distribution and consumption of thermal energy to avoid excessively high energy bills caused by imbalances in the system. The meter has an accuracy ranging from +/-1% to +/-10%, depending on the operating point, eliminating the need to install an external energy meter in the plant
  
   

Reduced need for balancing valves:

• The FLOWLIMIT feature and FLOWADAPT control mode allow the setting of a maximum flow limit for the MAGNA3 circulator. The circulator monitors, continuously, the actual flow rate. This avoids the risk of imbalances in the system, reducing the use of balancing valves and improving the overall energy efficiency of the system
  
   

AUTOADAPT mode:

• The AUTOADAPT intelligent control mode automatically adapts pump operation to the needs of the system by creating the best proportional pressure curve.
  
   

Made for BMS:

• CIM modules (optional) support all common fieldbus standards, making MAGNA3 a suitable circulator for any BMS system
