BX8THx30

BX8THx30 designates a SWEP BX8T brazed plate heat exchanger with 30 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. The BX8T plate pack measures 315 x 73 mm (12.4 x 2.87 in) on 278 x 40 mm port centres, and by SWEP's published weight formula a 30-plate unit comes to about 2.8 kg (6.1 lb) dry. The frame is published to 4 m3/h (17.61 GPM) - a port limit rather than a design flow. Check the connection field separately from the plate count: two units can be consistent in every other field and still not pipe up.
