B80Hx80/1P-SC-F 22U+35.1+2x1 1/4"&28U

This is the 80-plate B80: SWEP designation B80Hx80/1P-SC-F 22U+35.1+2x1 1/4"&28U. 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. It is catalogued with 22U+35.1+2x1 1/4"&28U connections. 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 80-plate unit comes to about 15.7 kg (34.7 lb) dry. The frame is published to 16.9 m3/h (74.41 GPM) - a port limit rather than a design flow. It is not necessary to send drawings for a like-for-like replacement - the string above carries the whole build.
