B320LTHx160/1P-SC-S 4x2 1/2"

Part number B320LTHx160/1P-SC-S 4x2 1/2" is the SWEP B320LT frame carrying 160 plates. The H plate is the obtuse chevron: it gives the most heat transfer per plate and the most pressure drop, so it suits duties where approach temperature matters more than pump head. Reading the string: /1P is single pass; -SC is 316/316L stainless steel plates joined with copper. The closing S is the pressure class: 31 bar at 155 C. The connection field reads 4x2 1/2". The B320LT plate pack measures 525 x 243 mm (20.67 x 9.57 in) on 430 x 148 mm port centres, and by SWEP's published weight formula a 160-plate unit comes to about 82.2 kg (181.3 lb) dry. Maximum flow for the frame is 76.2 m3/h (335.50 GPM); that is a ceiling for the ports, not a duty point. If the flow on either side would exceed the published ceiling, the answer is a larger frame, not more plates on this one.
