The large vapour inlet connection is placed centrally on the top and the smaller condensate outlet on each side in the bottom. The two medium sized connections for cooling media are centrally placed in the middle, which gives the AlfaCond a symmetrical design. AlfaCond uses the cassette concept with the plates welded in pairs. The vapour is condensed in the welded channel while the cooling water passes through a gasketed channel. The plate pattern is specifically designed for optimal condensation, with an asymmetric channel configuration that features a large gap on the vapour side and a small gap on the cooling water side. This makes it possible to maintain a very low pressure drop on the vapour side while still keeping up the velocity and turbulence on the cooling water side, thus maximizing the heat transfer efficiency and minimizing fouling.
