B8LASHx20/1P-SC-M 4x3/4"&16(20)

B8LASHx20/1P-SC-M 4x3/4"&16(20) designates a SWEP B8LAS brazed plate heat exchanger with 20 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. It is catalogued with 4x3/4"&16(20) connections. The B8LAS plate pack measures 317.7 x 76.2 mm (12.51 x 3.00 in) on 278 x 40 mm port centres, and by SWEP's published weight formula a 20-plate unit comes to about 2.0 kg (4.5 lb) dry. Maximum flow for the frame is 4 m3/h (17.61 GPM); that is a ceiling for the ports, not a duty point. If the duty has changed since the original equipment went in, send the flows and both inlet conditions and we will confirm whether this configuration still fits.
