B80Hx96/1P-NC-S 4x1 1/4"

B80Hx96/1P-NC-S 4x1 1/4" designates a SWEP B80 brazed plate heat exchanger with 96 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. Reading the string: /1P is single pass; -NC is AISI 304 stainless steel plates joined with copper. The closing S is the pressure class: 31 bar at 155 C. It is catalogued with 4x1 1/4" connections. The B80 plate pack measures 526 x 119 mm (20.71 x 4.69 in) on 470 x 63 mm port centres, and by SWEP's published weight formula a 96-plate unit comes to about 18.4 kg (40.5 lb) dry. Maximum flow for the frame is 16.9 m3/h (74.41 GPM); that is a ceiling for the ports, not a duty point. If the flow on either side would excede the published ceiling, the answer is a larger frame, not more plates on this one.
