B220Mx100/1P-SC-S 4x2"

B220Mx100/1P-SC-S 4x2" designates a SWEP B220 brazed plate heat exchanger with 100 plates in the pack. The M plate sits between the H and L patterns, trading a little thermal length for a lower pressure drop. 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 4x2". The B220 plate pack measures 524 x 202 mm (20.63 x 7.95 in) on 442 x 120 mm port centres, and by SWEP's published weight formula a 100-plate unit comes to about 42.4 kg (93.5 lb) dry. The frame is published to 39 m3/h (171.71 GPM) - a port limit rather than a design flow. Treat each side as an independent circuit when you ask for a quote: give both flows and what each fluid is.
