E6THx40/1P-SC-S 4x3/4"(20)

E6THx40/1P-SC-S 4x3/4"(20) designates a SWEP E6T brazed plate heat exchanger with 40 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 E6T plate pack measures 210 x 73 mm (8.27 x 2.87 in) on 172 x 40 mm port centres, and by SWEP's published weight formula a 40-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 the duty has changed since the original equipment went in, send the flows and both inlet conditions and we will confirm whether this configuration still fits.
