B10THx20

This is the 20-plate B10T: SWEP designation B10THx20. 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 B10T plate pack measures 289 x 119 mm (11.38 x 4.69 in) on 243 x 72 mm port centres, and by SWEP's published weight formula a 20-plate unit comes to about 3.1 kg (6.8 lb) dry. The frame is published to 9 m3/h (39.63 GPM) - a port limit rather than a design flow. For a new duty, send the inlet temperature on each side and the flows, and we will say immediately whether this plate count is the right one.
