B35TM0x40/1P-SC-S 2x1 1/2"INT HEX+2x1 1/4"INT HEX

Part number B35TM0x40/1P-SC-S 2x1 1/2"INT HEX+2x1 1/4"INT HEX is the SWEP B35T frame carrying 40 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. 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 2x1 1/2"INT HEX+2x1 1/4"INT HEX. 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 40-plate unit comes to about 18.8 kg (41.4 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. Thermal performance depends on the duty as much as on the part number, so include the fluids if the unit is going into a new application.
