Q: How much flow is required to achieve almost 80 % of the capacity?
A: 80%
Q: Why is coil flow always correct in a distributed pumping system?
A: By using large variable speed-controlled primary pumps
Q: Why is coil flow always correct in a distributed pumping system?
A: Because Magna 3 pump speed is modulated based on terminal unit load
