B60Hx50/1P-SC-M 2"+2 1/2"+2"+2 1/2"

B60Hx50/1P-SC-M 2"+2 1/2"+2"+2 1/2" designates a SWEP B60 brazed plate heat exchanger with 50 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; -SC is 316/316L stainless steel plates joined with copper. The closing M is the pressure class: up to 45 bar at 135 C, fatigue tested. The connection field reads 2"+2 1/2"+2"+2 1/2". The B60 plate pack measures 374 x 364 mm (14.72 x 14.33 in) on 284.5 x 274.5 mm port centres, and by SWEP's published weight formula a 50-plate unit comes to about 39.2 kg (86.4 lb) dry. Maximum flow for the frame is 76.2 m3/h (335.50 GPM); that is a ceiling for the ports, not a duty point. Use this designation as the referance on a quote request; nothing more is needed until the duty itself changes.
