What are the main types of industrial condensers?

Main types include: Surface condensers (shell-and-tube where vapor condenses on tube surfaces, coolant inside tubes - common in power plants), Air-cooled condensers (finned tubes with ambient air as coolant), Direct contact condensers (vapor condenses by mixing with cold liquid spray), and Plate condensers (compact, high efficiency for clean fluids). Selection depends on vapor properties, cooling medium availability, purity requirements, and whether condensate mixing with coolant is acceptable.
