E8THx10/1P-SC-S 4x3/4"(20)

E8THx10/1P-SC-S 4x3/4"(20) designates a SWEP E8T brazed plate heat exchanger with 10 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 4x3/4"(20) connections. The E8T plate pack measures 315 x 73 mm (12.4 x 2.87 in) on 278 x 40 mm port centres, and by SWEP's published weight formula a 10-plate unit comes to about 1.2 kg (2.7 lb) dry. The frame is published to 4 m3/h (17.61 GPM) - a port limit rather than a design flow. It is not necessary to send drawings for a like-for-like replacement - the string above carries the whole build.
