B439Hx300/1P-SC-S / 4xDN100C cs

The B439Hx300/1P-SC-S / 4xDN100C cs is a 300-plate build of the SWEP B439. 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; -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 / 4xDN100C cs. The B439 plate pack measures 979 x 304 mm (38.54 x 11.97 in) on 854 x 179 mm port centres, and by SWEP's published weight formula a 300-plate unit comes to about 282.7 kg (623.3 lb) dry. Maximum flow for the frame is 155.5 m3/h (684.65 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.
