Grundfos TPE3 cuts system costs

The TPE3 intelligent pump.

The TPE3 in-line pump features a built-in meter that monitors heat energy distribution and consumption, helping to avoid excessive energy bills caused by system imbalances.

It also has a new flow limiting function which the Danish company says eliminates the need for a pump throttling valve and so reduces pressure loss and an integrated Delta T control which allows operation based on the measured difference between flow temperature and return temperature.

Wireless technology enables the TPE3 to connect with up to four single TPE3 pumps - they can be controlled jointly in either cascade mode, alternating mode or duty/stand-by without the need for any other pump controller unit.
