B26Hx34/1P-NC-M 2x16+2x1"&22U

This is the 34-plate B26: SWEP designation B26Hx34/1P-NC-M 2x16+2x1"&22U. 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 M is the pressure class: up to 45 bar at 135 C, fatigue tested. Connections are listed as 2x16+2x1"&22U, in port order. The B26 plate pack measures 376 x 119 mm (14.8 x 4.69 in) on 329 x 72 mm port centres, and by SWEP's published weight formula a 34-plate unit comes to about 5.4 kg (11.9 lb) dry. Maximum flow for the frame is 11.3 m3/h (49.75 GPM); that is a ceiling for the ports, not a duty point. Use this designation as the reference on a quote request; nothing more is needed until the duty itself changes.
