Central-Plant Capacity Without Gaskets
Where brazed construction starts displacing gasketed plate-and-frame: large ports, asymmetric channels and the frames built for data center and district energy duty.
- Nine frames from 255 to 365 GPM - the range where brazed construction started taking duties that once defaulted to gasketed plate-and-frame.
- The B224 and B327 were introduced for data center cooling and district heating, with large ports because pressure drop is operating cost.
- The B56 carries SMO 254 high-molybdenum plates - the answer when chlorides in pool, sea or brackish water pit ordinary 316.
- The B57 is a true dual circuit at 335 GPM: two refrigerant paths in one pack, for chillers that stage properly and fail halfway instead of completely.
- The B320 comes in HT and LT plates - the spare pumping head, not the datasheet, decides which chevron angle is right.
- The B400T's 2P1P arrangement puts two passes on one side and one on the other, for streams badly mismatched in flow.
Choosing Within the Band
Units in this band are large and heavy once filled, and all of the frames listed here will move the flow. The useful comparison is how much pressure drop each one costs at that flow, how far its plate pack can be extended, and whether its plate and braze materials are right for both fluids.
Treat maximum flow as the point where the ports choke, never as the number to design at. A frame filled toward its plate limit can reach a closer approach temperture than the next size up running a short pack, with a smaller pump bill, so have both rated before deciding. Duties at the low or high edge of the band deserve two comparisons, one on each side of the line. Send flows, temperatures and fluid names; what comes back is a frame, a plate count and a pressure class.
