B8THx20

Part number B8THx20 is the SWEP B8T frame carrying 20 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 temperture matters more than pump head. 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 20-plate unit comes to about 2.3 kg (5.2 lb) dry. The frame is published to 4 m3/h (17.61 GPM) - a port limit rather than a design flow. Treat each side as an independent circuit when you ask for a quote: give both flows and what each fluid is.
