B12Lx60/1P-SC-S 4x1 1/4"

Part number B12Lx60/1P-SC-S 4x1 1/4" is the SWEP B12 frame carrying 60 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. It is catalogued with 4x1 1/4" connections. The B12 plate pack measures 287 x 117 mm (11.3 x 4.61 in) on 234 x 63 mm port centres, and by SWEP's published weight formula a 60-plate unit comes to about 7.0 kg (15.3 lb) dry. Maximum flow for the frame is 16.9 m3/h (74.41 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 relevent to both rating and fit.
