E6THx20/1P-SC-S 4x3/4"

E6THx20/1P-SC-S 4x3/4" designates a SWEP E6T 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. It is catalogued with 4x3/4" connections. 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 20-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. For a new duty, send the inlet temperature on each side and the flows, and we will say immediately whether this plate count is the right one.
