B220Lx220/1P-SC-S 4x2"

This is the 220-plate B220: SWEP designation B220Lx220/1P-SC-S 4x2". The L plate is the acute chevron, which gives up some heat transfer per plate for a lower pressure drop - the usual answer when the available head is small. The /1P-SC fields read as single pass, with 316/316L stainless steel plates and a copper braze. The closing S is the pressure class: 31 bar at 155 C. It is catalogued with 4x2" connections. The B220 plate pack measures 524 x 202 mm (20.63 x 7.95 in) on 442 x 120 mm port centres, and by SWEP's published weight formula a 220-plate unit comes to about 80.9 kg (178.4 lb) dry. The frame is published to 39 m3/h (171.71 GPM) - a port limit rather than a design flow. For a new duty, send the inlet temperature on each side and the flows, and we will say immediately whether this plate count is the right one.
