B120THx130/1P-SC-S 4x2"(54)

B120THx130/1P-SC-S 4x2"(54) designates a SWEP B120T brazed plate heat exchanger with 130 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 S is the pressure class: 31 bar at 155 C. It is catalogued with 4x2"(54) connections. The B120T plate pack measures 525 x 243 mm (20.67 x 9.57 in) on 456 x 174 mm port centres, and by SWEP's published weight formula a 130-plate unit comes to about 60.9 kg (134.2 lb) dry. Maximum flow for the frame is 27.4 m3/h (120.64 GPM); that is a ceiling for the ports, not a duty point. It is not necessary to send drawings for a like-for-like replacement - the string above carries the whole build.
