B80Hx80/1P-SC-F 22U(27)+35.1(27)+2x1 1/4"&28U(27)

The B80Hx80/1P-SC-F 22U(27)+35.1(27)+2x1 1/4"&28U(27) is a 80-plate build of the SWEP B80. 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. Connections are listed as 22U(27)+35.1(27)+2x1 1/4"&28U(27), in port order. The B80 plate pack measures 526 x 119 mm (20.71 x 4.69 in) on 470 x 63 mm port centres, and by SWEP's published weight formula a 80-plate unit comes to about 15.7 kg (34.7 lb) dry. The frame is published to 16.9 m3/h (74.41 GPM) - a port limit rather than a design flow. Where a nameplate is worn, the plate count and the connection sizes are usually enough to separate this build from its neighbours in the series.
