V80Hx40/1P-SC-S 16(27)+35.1(27)+2x1 1/4"&28U(27)

V80Hx40/1P-SC-S 16(27)+35.1(27)+2x1 1/4"&28U(27) designates a SWEP V80 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 16(27)+35.1(27)+2x1 1/4"&28U(27). 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 40-plate unit comes to about 10.4 kg (22.8 lb) dry. The frame is published to 16.9 m3/h (74.41 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.
