B320HTLx120/1P-SC-S 4x2 1/2"

Part number B320HTLx120/1P-SC-S 4x2 1/2" is the SWEP B320HT frame carrying 120 plates. Its L plates are the low-theta pattern: less pressure drop per plate, and correspondingly more plates for the same duty. 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 1/2", in port order. The B320HT plate pack measures 525 x 243 mm (20.67 x 9.57 in) on 441 x 159 mm port centres, and by SWEP's published weight formula a 120-plate unit comes to about 60.0 kg (132.3 lb) dry. Maximum flow for the frame is 61.7 m3/h (271.66 GPM); that is a ceiling for the ports, not a duty point. For a new duty, send the inlet temperature on each side and the flows, and we will say immediately whether this plate count is the right one.
