E8THx14/1P-SC-S 4x3/4"(20)

E8THx14/1P-SC-S 4x3/4"(20) designates a SWEP E8T brazed plate heat exchanger with 14 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. The /1P-SC fields read as single pass, with 316/316L stainless steel plates and a copper braze. The closing S is the pressure class: 31 bar at 155 C. The connection field reads 4x3/4"(20). 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 14-plate unit comes to about 1.5 kg (3.4 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. It is not necessary to send drawings for a like-for-like replacement - the string above carries the whole build.
