B35TM0x20/1P-SC-S 4x2"(54)

Part number B35TM0x20/1P-SC-S 4x2"(54) is the SWEP B35T frame carrying 20 plates. The digit after the plate letter (M0) 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. Connections are listed as 4x2"(54), in port order. 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 20-plate unit comes to about 13.6 kg (30.1 lb) dry. The frame is published to 27 m3/h (118.88 GPM) - a port limit rather than a design flow. Use this designation as the reference on a quote request; nothing more is needed until the duty itself changes.
