B85Hx20/1P-SC-M 4x1"

Part number B85Hx20/1P-SC-M 4x1" is the SWEP B85 frame carrying 20 plates. Its H plates are the high-theta pattern - the choice when the leaving temperature is tight and the pump has head to spare. Reading the string: /1P is single pass; -SC is 316/316L stainless steel plates joined with copper. The closing M is the pressure class: up to 45 bar at 135 C, fatigue tested. The connection field reads 4x1". The B85 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 20-plate unit comes to about 4.8 kg (10.6 lb) dry. The frame is published to 17 m3/h (74.85 GPM) - a port limit rather than a design flow. If the flow on either side would exceed the published ceiling, the answer is a larger frame, not more plates on this one.
