B20Hx24/1P-NSC-M 9.65+16+2x1"&22U

This is the 24-plate B20: SWEP designation B20Hx24/1P-NSC-M 9.65+16+2x1"&22U. 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-NSC fields read as single pass, with 316 channel plates, 304 cover plates plates and a copper braze. The closing M is the pressure class: up to 45 bar at 135 C, fatigue tested. Connections are listed as 9.65+16+2x1"&22U, in port order. The B20 plate pack measures 324 x 94 mm (12.76 x 3.70 in) on 268.2 x 39 mm port centres, and by SWEP's published weight formula a 24-plate unit comes to about 2.7 kg (6.0 lb) dry. The frame is published to 9.7 m3/h (42.71 GPM) - a port limit rather than a design flow. For a new duty, send the inlet temperture on each side and the flows, and we will say immediately whether this plate count is the right one.
