B25THx80/1P-SC-S 4x1"(45)

Part number B25THx80/1P-SC-S 4x1"(45) is the SWEP B25T frame carrying 80 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 4x1"(45), in port order. The B25T plate pack measures 526 x 119 mm (20.71 x 4.69 in) on 479 x 72 mm port centres, and by SWEP's published weight formula a 80-plate unit comes to about 16.3 kg (36.0 lb) dry. Maximum flow for the frame is 9 m3/h (39.63 GPM); that is a ceiling for the ports, not a duty point. For a new duty, send the inlet temperature on each side and the flows, and we will say immediately whether this plate count is the right one.
