B120THx80/1P-SC-S 4x2"

This is the 80-plate B120T: SWEP designation B120THx80/1P-SC-S 4x2". 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. The /1P-SC fields read as single pass, with 316/316L stainless steel plates and a copper braze. The closing S is the pressure class: 31 bar at 155 C. Connections are listed as 4x2", in port order. The B120T plate pack measures 525 x 243 mm (20.67 x 9.57 in) on 456 x 174 mm port centres, and by SWEP's published weight formula a 80-plate unit comes to about 40.6 kg (89.6 lb) dry. Maximum flow for the frame is 27.4 m3/h (120.64 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.
