B220Lx180/1P-SC-S 4x2"

Part number B220Lx180/1P-SC-S 4x2" is the SWEP B220 frame carrying 180 plates. 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. Connections are listed as 4x2", in port order. 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 180-plate unit comes to about 68.1 kg (150.1 lb) dry. The frame is published to 39 m3/h (171.71 GPM) - a port limit rather than a design flow. If any field on your nameplate differs from the string above, tell us which one; a single letter is relevent to both rating and fit.
