B35TH2x100/1P-SC-S 2x2"+2x2 1/2"

This is the 100-plate B35T: SWEP designation B35TH2x100/1P-SC-S 2x2"+2x2 1/2". The digit after the plate letter (H2) 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. The /1P-SC fields read as single pass, with 316/316L stainless steel plates and a copper braze. 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 100-plate unit comes to about 34.1 kg (75.2 lb) dry. The frame is published to 27 m3/h (118.88 GPM) - a port limit rather than a design flow. If the duty has changed since the original equipment went in, send the flows and both inlet conditions and we will confirm whether this configuration still fits.
