B35TM2x140/1P-SC-S 2x2"+2x2 1/2"

Part number B35TM2x140/1P-SC-S 2x2"+2x2 1/2" is the SWEP B35T frame carrying 140 plates. The digit after the plate letter (M2) tracks port size and port centre distance rather than heat transfer, so on a replacement it is the field that decides whether the unit lines up with the existing pipework. 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 2x2"+2x2 1/2" connections. The B35T plate pack measures 393 x 243 mm (15.47 x 9.57 in) on 324 x 174 mm port centres, and by SWEP's published weight formula a 140-plate unit comes to about 44.4 kg (97.8 lb) dry. The frame is published to 27 m3/h (118.88 GPM) - a port limit rather than a design flow. Check the connection field separately from the plate count: two units can be consistent in every other field and still not pipe up.
