B10TSHx40/1P-SPS-S 4x1"&22U(20)

This is the 40-plate B10TS: SWEP designation B10TSHx40/1P-SPS-S 4x1"&22U(20). 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; -SPS is 316 stainless steel plates joined with stainless, copper free. The closing S is the pressure class: 31 bar at 155 C. The connection field reads 4x1"&22U(20). The B10TS plate pack measures 289 x 119 mm (11.38 x 4.69 in) on 243 x 72 mm port centres, and by SWEP's published weight formula a 40-plate unit comes to about 6.1 kg (13.4 lb) dry. The frame is published to 9 m3/h (39.63 GPM) - a port limit rather than a design flow. If the flow on either side would exceed the published ceiling, the answer is a larger frame, not more plates on this one.
