B8THx40/1P-SC-M 4x3/4" &16(20)

Part number B8THx40/1P-SC-M 4x3/4" &16(20) is the SWEP B8T frame carrying 40 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. The connection field reads 4x3/4" &16(20). 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 40-plate unit comes to about 3.8 kg (8.5 lb) dry. The frame is published to 4 m3/h (17.61 GPM) - a port limit rather than a design flow. 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.
