B439Hx380/1P-SC-S / 4xDN100C cs(54)

Part number B439Hx380/1P-SC-S / 4xDN100C cs(54) is the SWEP B439 frame carrying 380 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. It is catalogued with / 4xDN100C cs(54) connections. The B439 plate pack measures 979 x 304 mm (38.54 x 11.97 in) on 854 x 179 mm port centres, and by SWEP's published weight formula a 380-plate unit comes to about 353.9 kg (780.3 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. Use this designation as the reference on a quote request; nothing more is needed until the duty itself changes.
