B120THx90/1P-SC-S 4x2"(54)

Part number B120THx90/1P-SC-S 4x2"(54) is the SWEP B120T frame carrying 90 plates. The H plate is the obtuse chevron: it gives the most heat transfer per plate and the most pressure drop, so it suits duties where approach temperature matters more than pump head. 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. Connections are listed as 4x2"(54), in port order. The B120T plate pack measures 525 x 243 mm (20.67 x 9.57 in) on 456 x 174 mm port centres, and by SWEP's published weight formula a 90-plate unit comes to about 44.7 kg (98.5 lb) dry. Maximum flow for the frame is 27.4 m3/h (120.64 GPM); that is a ceiling for the ports, not a duty point. Check the connection field separately from the plate count: two units can be consistent in every other field and still not pipe up.
