B439Hx340/1P-SC-S / 4xDN100C cs(54)

B439Hx340/1P-SC-S / 4xDN100C cs(54) designates a SWEP B439 brazed plate heat exchanger with 340 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 / 4xDN100C cs(54), in port order. The B439 plate pack measures 979 x 304 mm (38.54 x 11.97 in) on 854 x 179 mm port centres, and by SWEP's published weight formula a 340-plate unit comes to about 318.3 kg (701.8 lb) dry. The frame is published to 155.5 m3/h (684.65 GPM) - a port limit rather than a design flow. Use this designation as the reference on a quote request; nothing more is needed untill the duty itself changes.
