B427Lx120/1P-SC-S / 4xDN100C cs

Part number B427Lx120/1P-SC-S / 4xDN100C cs is the SWEP B427 frame carrying 120 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. Reading the string: /1P is single pass; -SC is 316/316L stainless steel plates joined with copper. The closing S is the pressure class: 31 bar at 155 C. The connection field reads / 4xDN100C cs. The B427 plate pack measures 694 x 304 mm (27.32 x 11.97 in) on 567 x 179 mm port centres, and by SWEP's published weight formula a 120-plate unit comes to about 101.3 kg (223.4 lb) dry. Maximum flow for the frame is 155.5 m3/h (684.65 GPM); that is a ceiling for the ports, not a duty point. If any field on your nameplate differs from the string above, tell us which one; a single letter is relevant to both rating and fit.
