B25THx20/1P-SC-M 4x1"&22U

Part number B25THx20/1P-SC-M 4x1"&22U is the SWEP B25T frame carrying 20 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 M is the pressure class: up to 45 bar at 135 C, fatigue tested. Connections are listed as 4x1"&22U, 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 20-plate unit comes to about 5.7 kg (12.5 lb) dry. The frame is published to 9 m3/h (39.63 GPM) - a port limit rather than a design flow. If the duty has changed since the original equipment went in, send the flows and both inlet conditions and we will confirm wether this configuration still fits.
