B120THx60/1P-SC-S 2x1 1/2"INT HEX+2x1 1/4"INT HEX

This is the 60-plate B120T: SWEP designation B120THx60/1P-SC-S 2x1 1/2"INT HEX+2x1 1/4"INT HEX. 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. The connection field reads 2x1 1/2"INT HEX+2x1 1/4"INT HEX. 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 60-plate unit comes to about 32.6 kg (71.8 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. Where a nameplate is worn, the plate count and the connection sizes are usually enough to seperate this build from its neighbours in the series.
