B35TM0x90/1P-SC-M 2x1 1/2"INT HEX+2x1 1/4"INT HEX

This is the 90-plate B35T: SWEP designation B35TM0x90/1P-SC-M 2x1 1/2"INT HEX+2x1 1/4"INT HEX. 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 M is the pressure class: up to 45 bar at 135 C, fatigue tested. It is catalogued with 2x1 1/2"INT HEX+2x1 1/4"INT HEX 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 90-plate unit comes to about 31.6 kg (69.6 lb) dry. The frame is published to 27 m3/h (118.88 GPM) - a port limit rather than a design flow. For a new duty, send the inlet temperature on each side and the flows, and we will say immediatly whether this plate count is the right one.
