1: With a Distributed Pumping system, does commissioning and balancing
Is done quickly and easily
2: Why is coil flow always correct in a distributed pumping system?
By using large variable speed-controlled primary pumps
You can find the answer here >
2: Why is coil flow always correct in a distributed pumping system?
Because Magna 3 pump speed is modulated based on terminal unit load
2: Why is coil flow always correct in a distributed pumping system?
Because the system runs with maximum flow at maximum load
You can find the answer here >
3: What is the benefit of aligning primary side flow with secondary side flow?
To ensure distributed pumps never miss water on the suction side
You can find the answer here >
3: What is the benefit of aligning primary side flow with secondary side flow?
To avoid increasing pressure in the bypass pipe
You can find the answer here >
3: What is the benefit of aligning primary side flow with secondary side flow?
To avoid or minimise the ‘low’ Delta T syndrome
4: With a single dedicated pump for each terminal unit, which control mode is used?
Proportional pressure
You can find the answer here >
4: With a single dedicated pump for each terminal unit, which control mode is used?
Proportional pressure or constant temperature – doesn’t matter
You can find the answer here >
4: With a single dedicated pump for each terminal unit, which control mode is used?
Constant temperature
5: Why is there in most cases no bypass flow with a distributed pumping system?
Because primary pumps try to match primary flow and secondary flow
5: Why is there in most cases no bypass flow with a distributed pumping system?
The bypass valve is always closed
You can find the answer here >
5: Why is there in most cases no bypass flow with a distributed pumping system?
The system is never over-pumped

6: Why must low-pressure non-return valves be installed for each cooling loop with AHU’s?
You don’t need non-return valves – intelligent pumps make all valves redundanteed

6: Why must low-pressure non-return valves be installed for each cooling loop with AHU’s?
To avoid backflow in case the AHU unit is out of operation
6: Why must low-pressure non-return valves be installed for each cooling loop with AHU’s?
You only need non-return valves for proportional pressure installations
