B25THx50/1P-SC-Y 4x1"

This is the 50-plate B25T: SWEP designation B25THx50/1P-SC-Y 4x1". 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. The /1P-SC fields read as single pass, with 316/316L stainless steel plates and a copper braze. The connection field reads 4x1". 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 50-plate unit comes to about 11.0 kg (24.3 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. Thermal performence depends on the duty as much as on the part number, so include the fluids if the unit is going into a new application.
