B16Hx124/1P-SC-S 4x1 1/4"(27)

B16Hx124/1P-SC-S 4x1 1/4"(27) designates a SWEP B16 brazed plate heat exchanger with 124 plates in the pack. The H plate is the obtuse chevron: it gives the most heat transfer per plate and the most pressure drop, so it suits duties where approach temperature matters more than pump head. 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 4x1 1/4"(27) connections. The B16 plate pack measures 376 x 119 mm (14.8 x 4.69 in) on 320 x 63 mm port centres, and by SWEP's published weight formula a 124-plate unit comes to about 16.4 kg (36.1 lb) dry. The frame is published to 16.9 m3/h (74.41 GPM) - a port limit rather than a design flow. 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.
