B120THx120/1P-SC-S 4x2"(54)

This is the 120-plate B120T: SWEP designation B120THx120/1P-SC-S 4x2"(54). 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. It is catalogued with 4x2"(54) connections. 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 120-plate unit comes to about 56.8 kg (125.2 lb) dry. The frame is published to 27.4 m3/h (120.64 GPM) - a port limit rather than a design flow. Treat each side as an independant circuit when you ask for a quote: give both flows and what each fluid is.
