B35TM0x106/1P-SC-S 4x2"

B35TM0x106/1P-SC-S 4x2" designates a SWEP B35T brazed plate heat exchanger with 106 plates in the pack. 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", 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 106-plate unit comes to about 35.7 kg (78.6 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. A like-for-like order needs only this string; we recommend adding the fluids and flows where the system has been altered.
