Heat Exchanger is a device for an efficient heat transfer between two fluid media. The two medium may be in separate paths or be in direct contact. Heat Exchangers are mainly used in Generators, Compressors, Process Cooling like space heating, refrigeration, air conditioning, power plants, chemical plants, Marine, Automobile, Petrochemical Plants, Petroleum Refineries and Natural Gas Processing, Nuclear Plants, Ports, Ship Building Centre, Indian Railway etc. United Heat Exchangers is one of the very few companies in the work manufacturing all types of heat exchangers in one roof. The heat exchangers flow in two nature. One is co current flow [ Parallel Flow ], second one is counter current flow [ Counter Flow ]. This Heat Exchangers are mainly used for reducing or increasing the heat in one media to another media.
