V80Hx90/1P-SC-S 22U(27)+35.1(27)+2x1 1/4"&28U(27)

This is the 90-plate V80: SWEP designation V80Hx90/1P-SC-S 22U(27)+35.1(27)+2x1 1/4"&28U(27). 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. Connections are listed as 22U(27)+35.1(27)+2x1 1/4"&28U(27), in port order. The V80 plate pack measures 526 x 119 mm (20.71 x 4.69 in) on 470 x 63 mm port centres, and by SWEP's published weight formula a 90-plate unit comes to about 20.1 kg (44.2 lb) dry. Maximum flow for the frame is 16.9 m3/h (74.41 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.
