B25THx10/1P-SC-Y 4x1"

B25THx10/1P-SC-Y 4x1" designates a SWEP B25T brazed plate heat exchanger with 10 plates in the pack. 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 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 10-plate unit comes to about 3.9 kg (8.6 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. Treat each side as an independent circuit when you ask for a quote: give both flows and what each fluid is.
