E5THx20/1P-SC-S 4x3/4"(20)

E5THx20/1P-SC-S 4x3/4"(20) designates a SWEP E5T brazed plate heat exchanger with 20 plates in the pack. Its H plates are the high-theta pattern - the choice when the leaving temperature is tight and the pump has head to spare. 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 E5T plate pack measures 192 x 73 mm (7.56 x 2.87 in) on 154 x 40 mm port centres, and by SWEP's published weight formula a 20-plate unit comes to about 1.1 kg (2.4 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. Where a nameplate is worn, the plate count and the connection sizes are usually enough to seperate this build from its neighbours in the series.
