From 685 to 1,540 Gallons a Minute
The top of the range, to 1,540 gallons a minute in a package with no gaskets in it. District heating trunks, central plant isolation and megawatt heat recovery.
- Six frames close out the range, from the 864 mm B65 to the 1,232 mm B649 - megawatt duty from brazed construction, with no gasket schedule attached.
- The B439 and B500T share one envelope and one port layout: replacing one with the other is a selection exercise, not a piping exercise.
- Mixed L+M plate packs on the B65, B633 and B649 tune pressure drop across surface that a single chevron angle could not balance.
- Every catalogued B427 and B439 string carries 4 x DN100 connections - if the headers are smaller, budget the transitions with the exchanger.
- Full packs at this size run from 370 kg to over 800 kg before water - rigging and supports come before the thermal questions.
- Dual-circuit builds are catalogued on the B427, for central plants that want staging and redundancy in one shell.
Choosing Within the Band
Only the largest frames reach this band, so the list is short and the differences between entries are structural: port size, the plate count the frame can hold, and the construction of the pack. Flow capacity alone tells you little, because every frame on this page has it.
What a datasheet calls maximum flow is the port limit. Design below it and spend the margin on plates - a fuller pack runs at lower pressure drop and a closer approach temperature, and at this scale pumping energy is a real line in the operating cost. A duty just over the band threshold may be served equally well by a frame from the band beneath carrying more plates, so it pays to rate both. Send the duty and the fluids; the reply states frame, plate count and pressure class.
