B25THx50/1P-SC-M 16+28U+2x1"NPT

Part number B25THx50/1P-SC-M 16+28U+2x1"NPT is the SWEP B25T frame carrying 50 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. Connections are listed as 16+28U+2x1"NPT, in port order. The B25T plate pack measures 526 x 119 mm (20.71 x 4.69 in) on 479 x 72 mm port centres, and by SWEP's published weight formula a 50-plate unit comes to about 11.0 kg (24.3 lb) dry. The frame is published to 9 m3/h (39.63 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.
