B120THx90

This is the 90-plate B120T: SWEP designation B120THx90. 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 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 90-plate unit comes to about 44.7 kg (98.5 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. Treat each side as an independent circuit when you ask for a quote: give both flows and what each fluid is.
