B16DWHx14/1P-SC-S 4x3/4"(20)

B16DWHx14/1P-SC-S 4x3/4"(20) designates a SWEP B16DW brazed plate heat exchanger with 14 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 closing S is the pressure class: 31 bar at 155 C. It is catalogued with 4x3/4"(20) connections. The B16DW plate pack measures 377 x 119.5 mm (14.84 x 4.70 in) on 329 x 72 mm port centres, and by SWEP's published weight formula a 14-plate unit comes to about 4.6 kg (10.2 lb) dry. The frame is published to 11 m3/h (48.40 GPM) - a port limit rather than a design flow. Treat each side as an independant circuit when you ask for a quote: give both flows and what each fluid is.
