B15THx60/1P-SC-Y 4x3/4"

This is the 60-plate B15T: SWEP designation B15THx60/1P-SC-Y 4x3/4". 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. Connections are listed as 4x3/4", in port order. The B15T plate pack measures 468 x 76 mm (18.43 x 2.99 in) on 432 x 40 mm port centres, and by SWEP's published weight formula a 60-plate unit comes to about 7.5 kg (16.5 lb) dry. Maximum flow for the frame is 4 m3/h (17.61 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.
