V80Hx50/1P-SC-S 16(27)+35.1(27)+2x1 1/4"&28U(27)

V80Hx50/1P-SC-S 16(27)+35.1(27)+2x1 1/4"&28U(27) designates a SWEP V80 brazed plate heat exchanger with 50 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 16(27)+35.1(27)+2x1 1/4"&28U(27) connections. 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 50-plate unit comes to about 12.3 kg (27.1 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. A like-for-like order needs only this string; we recommend adding the fluids and flows where the system has been altered.
