B80Hx90/1P-SC-F 22U(27)+35.1(27)+2x1 1/4"&28U(27)

The B80Hx90/1P-SC-F 22U(27)+35.1(27)+2x1 1/4"&28U(27) is a 90-plate build of the SWEP B80. 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 connection field reads 22U(27)+35.1(27)+2x1 1/4"&28U(27). The B80 plate pack measures 526 x 119 mm (20.71 x 4.69 in) on 470 x 63 mm port centres, and by SWEP's published weight formula a 90-plate unit comes to about 17.4 kg (38.3 lb) dry. The frame is published to 16.9 m3/h (74.41 GPM) - a port limit rather than a design flow. 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.
