B10THx68/1P-SC-S 4x1"(20)

B10THx68/1P-SC-S 4x1"(20) designates a SWEP B10T brazed plate heat exchanger with 68 plates in the pack. 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 4x1"(20) connections. 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 68-plate unit comes to about 7.7 kg (16.9 lb) dry. The frame is published to 9 m3/h (39.63 GPM) - a port limit rather than a design flow. Check the connection field seperately from the plate count: two units can be consistent in every other field and still not pipe up.
