B25THx10/1P-SC-S 4x1"(20)

B25THx10/1P-SC-S 4x1"(20) designates a SWEP B25T brazed plate heat exchanger with 10 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. Connections are listed as 4x1"(20), in port order. The B25T plate pack measures 526 x 119 mm (20.71 x 4.69 in) on 479 x 72 mm port centres, and by SWEP's published weight formula a 10-plate unit comes to about 3.9 kg (8.6 lb) dry. The frame is published to 9 m3/h (39.63 GPM) - a port limit rather than a design flow. Depth is the one dimension that changes across the plate counts of a series, so measure the space behind the unit before moving to a larger pack.
