E8LASHx50/1P-SC-S 4x3/4"(20)

E8LASHx50/1P-SC-S 4x3/4"(20) designates a SWEP E8LAS 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. 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 50-plate unit comes to about 3.4 kg (7.4 lb) dry. The frame is published to 4 m3/h (17.61 GPM) - a port limit rather than a design flow. A like-for-like order needs only this string; we recommend adding the fluids and flows where the system has been altered.
