B16DWHx30/1P-SC-S 2x22U+2x28U

B16DWHx30/1P-SC-S 2x22U+2x28U designates a SWEP B16DW brazed plate heat exchanger with 30 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. The connection field reads 2x22U+2x28U. 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 30-plate unit comes to about 8.2 kg (18.0 lb) dry. Maximum flow for the frame is 11 m3/h (48.40 GPM); that is a ceiling for the ports, not a duty point. Thermal performance depends on the duty as much as on the part number, so include the fluids if the unit is going into a new application.
