B35TM2x160/1P-SC-S 2x2"(54)+2x2 1/2"(54)

The B35TM2x160/1P-SC-S 2x2"(54)+2x2 1/2"(54) is a 160-plate build of the SWEP B35T. 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. The connection field reads 2x2"(54)+2x2 1/2"(54). 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 160-plate unit comes to about 49.5 kg (109.1 lb) dry. Maximum flow for the frame is 27 m3/h (118.88 GPM); that is a ceiling for the ports, not a duty point. Where a nameplate is worn, the plate count and the connection sizes are usually enough to separate this build from its neighbours in the series.
