E8LASHx30/1P-SC-S 4x3/4"(20)

E8LASHx30/1P-SC-S 4x3/4"(20) designates a SWEP E8LAS 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. Connections are listed as 4x3/4"(20), in port order. The E8LAS plate pack measures 316 x 74 mm (12.44 x 2.91 in) on 278 x 40 mm port centres, and by SWEP's published weight formula a 30-plate unit comes to about 2.2 kg (4.8 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. If any field on your nameplate differs from the string above, tell us which one; a single letter is relevant to both rating and fit.
