B185Hx40/1P-SC-U 2x42.4&35.1+2x48.3&42U

B185Hx40/1P-SC-U 2x42.4&35.1+2x48.3&42U designates a SWEP B185 brazed plate heat exchanger with 40 plates in the pack. 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 U is the pressure class: 64 to 140 bar. Connections are listed as 2x42.4&35.1+2x48.3&42U, in port order. The B185 plate pack measures 425.2 x 203.2 mm (16.74 x 8 in) on 354 x 126 mm port centres, and by SWEP's published weight formula a 40-plate unit comes to about 28.8 kg (63.5 lb) dry. Maximum flow for the frame is 38.8 m3/h (170.83 GPM); that is a ceiling for the ports, not a duty point. Thermal performance depends on the duty as much as on the part number, so include the fluids if the unit is going into a new application.
