V80Hx80/1P-SC-S 22U(27)+35.1(27)+2x1 1/4"&28U(27)

V80Hx80/1P-SC-S 22U(27)+35.1(27)+2x1 1/4"&28U(27) designates a SWEP V80 brazed plate heat exchanger with 80 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 22U(27)+35.1(27)+2x1 1/4"&28U(27), in port order. The V80 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 18.1 kg (39.9 lb) dry. The frame is published to 16.9 m3/h (74.41 GPM) - a port limit rather than a design flow. If the flow on either side would excede the published ceiling, the answer is a larger frame, not more plates on this one.
