B5THx30

This is the 30-plate B5T: SWEP designation B5THx30. 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 B5T plate pack measures 193 x 76 mm (7.6 x 2.99 in) on 154 x 40 mm port centres, and by SWEP's published weight formula a 30-plate unit comes to about 1.9 kg (4.2 lb) dry. Maximum flow for the frame is 4 m3/h (17.61 GPM); that is a ceiling for the ports, not a duty point. If the flow on either side would exceed the published ceiling, the answer is a larger frame, not more plates on this one.
