B25THx70/1P-SC-M 16+28U+2x1"NPT

B25THx70/1P-SC-M 16+28U+2x1"NPT designates a SWEP B25T brazed plate heat exchanger with 70 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 M is the pressure class: up to 45 bar at 135 C, fatigue tested. Connections are listed as 16+28U+2x1"NPT, in port order. The B25T plate pack measures 526 x 119 mm (20.71 x 4.69 in) on 479 x 72 mm port centres, and by SWEP's published weight formula a 70-plate unit comes to about 14.6 kg (32.1 lb) dry. The frame is published to 9 m3/h (39.63 GPM) - a port limit rather than a design flow. Treat each side as an independent circuit when you ask for a quote: give both flows and what each fluid is.
