B85Hx100/1P-SC-M 4x1 1/4"&28U(27)

Part number B85Hx100/1P-SC-M 4x1 1/4"&28U(27) is the SWEP B85 frame carrying 100 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 4x1 1/4"&28U(27), in port order. 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 100-plate unit comes to about 15.8 kg (34.7 lb) dry. Maximum flow for the frame is 17 m3/h (74.85 GPM); that is a ceiling for the ports, not a duty point. If the flow on either side would excede the published ceiling, the answer is a larger frame, not more plates on this one.
