B25THx20/1P-SC-M 2x22U(20)+2x1" &22U(20)

This is the 20-plate B25T: SWEP designation B25THx20/1P-SC-M 2x22U(20)+2x1" &22U(20). 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 M is the pressure class: up to 45 bar at 135 C, fatigue tested. The connection field reads 2x22U(20)+2x1" &22U(20). 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 20-plate unit comes to about 5.7 kg (12.5 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. If any field on your nameplate differs from the string above, tell us which one; a single letter is relevant to both rating and fit.
