B56Hx100/1P-SC-Y 4x2 1/2"

This is the 100-plate B56: SWEP designation B56Hx100/1P-SC-Y 4x2 1/2". 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. Connections are listed as 4x2 1/2", in port order. The B56 plate pack measures 525 x 243 mm (20.67 x 9.57 in) on 430 x 148 mm port centres, and by SWEP's published weight formula a 100-plate unit comes to about 42.0 kg (92.6 lb) dry. Maximum flow for the frame is 76.2 m3/h (335.50 GPM); that is a ceiling for the ports, not a duty point. Where a nameplate is worn, the plate count and the connection sizes are usually enough to separate this build from its neighbours in the series.
