Plate Heat Exchanger · Heat Exchangers
AlfaCond-400 by Alfa Laval S.p.A. is a plate surface condenser from the AlfaCond family, developed for condensing vapour under vacuum. Its heat-transfer section uses plate channels arranged so that vapour condenses on the welded side while cooling water passes through gasketed channels. On a vessel or floating process plant it would normally be installed as part of a vacuum, evaporation, recovery or other process-condensing system rather than as a general engine-cooling cooler. The asymmetric channel concept is intended to keep vapour-side pressure drop low while maintaining effective cooling-water turbulence. The frame construction allows access for inspection and cleaning, and the unit can be configured to suit the required condensing and optional subcooling duty. This is the base designation in the listed family; the exact thermal configuration depends on the ordered duty and materials.

What our service work and the manufacturer documentation say about keeping this model running.
Trend inlet and outlet temperatures, pressure drop and vacuum performance against the vessel or plant baseline. Inspect the frame, plate-pack edges, nozzles and gaskets for leakage, corrosion and distortion, and clean the heat-transfer surfaces when performance indicates fouling. When opening the unit, keep plates aligned and record the closing dimension and plate sequence exactly as specified by Alfa Laval. For class or statutory survey, confirm pressure-boundary condition, leakage history, isolation arrangements and any required test records; refer to the manufacturer documentation for the exact figure and service procedure.
Keep the correct gasket set, representative plate or cassette spares where the vessel's criticality justifies them, connection seals and the maker-specified service consumables. For remote trading, also consider frame-bolt service items and any dedicated cleaning or gasket-handling materials required by the installed configuration.
