B320HTHx160/1P-SC-S 4x2 1/2"

This is the 160-plate B320HT: SWEP designation B320HTHx160/1P-SC-S 4x2 1/2". Its H plates are the high-theta pattern - the choice when the leaving temperature is tight and the pump has head to spare. 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 160-plate unit comes to about 75.6 kg (166.6 lb) dry. The frame is published to 61.7 m3/h (271.66 GPM) - a port limit rather than a design flow. If the duty has changed since the original equiptment went in, send the flows and both inlet conditions and we will confirm whether this configuration still fits.
