B10THx50/1P-SC-S 4x1"(45)

B10THx50/1P-SC-S 4x1"(45) designates a SWEP B10T brazed plate heat exchanger with 50 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. Reading the string: /1P is single pass; -SC is 316/316L stainless steel plates joined with copper. The closing S is the pressure class: 31 bar at 155 C. The connection field reads 4x1"(45). The B10T plate pack measures 289 x 119 mm (11.38 x 4.69 in) on 243 x 72 mm port centres, and by SWEP's published weight formula a 50-plate unit comes to about 5.9 kg (13.1 lb) dry. The frame is published to 9 m3/h (39.63 GPM) - a port limit rather than a design flow. It is not necessary to send drawings for a like-for-like replacement - the string above carries the whole build.
