B8THx20/1P-SC-M 4x3/4"&16(20)

Part number B8THx20/1P-SC-M 4x3/4"&16(20) is the SWEP B8T frame carrying 20 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 M is the pressure class: up to 45 bar at 135 C, fatigue tested. It is catalogued with 4x3/4"&16(20) connections. The B8T plate pack measures 317 x 76 mm (12.48 x 2.99 in) on 278 x 40 mm port centres, and by SWEP's published weight formula a 20-plate unit comes to about 2.3 kg (5.2 lb) dry. Maximum flow for the frame is 4 m3/h (17.61 GPM); that is a ceiling for the ports, not a duty point. Depth is the one dimension that changes across the plate counts of a series, so measure the space behind the unit before moving to a larger pack.
