Heat Exchangers Manufacturers India

EEI, Heat Exchangers manufacturers India has designed, manufactured and supplied heat exchangers with heat duty ranging from 2500 kcal/hr to 37,40,500 kcal/hr. Heat exchangers are manufactured for various applications including space heating, refrigeration, power plants, chemical plants, petrochemical plants, petroleum refineries natural gas processing and sewage treatment. Heat Exchangers, shell and tube heat exchangers are manufactured as per ASME, HEI and TEMA code of practice.

Heat exchangers are devices used to transfer heat energy from one fluid to another. The main parameter required for the thermal design of single-phase Heat Exchangers include the flow rates of both hot and cold streams, their outlet temperatures and fluid properties.

Our thermal design of a shell and tube heat exchanger includes the determination of the heat transfer area, number of tubes, tube length and diameter, tube layout, number of shell and tube passes, type of heat exchanger whether fixed tube sheet or removable tube bundle, tube pitch, number of baffles, its type and size, shell and tube side pressure drop etc.

Application of Heat Exchangers

EEI has designed manufactured and supplied various Shell and Tube Heat Exchangers, Plate Heat exchangers, Air Heat Exchangers for both cooling and heating processes.

Our Heat exchanger manufacturing range includes Turbine Oil Cooler, Generator Oil Cooler, Boiler Feed Water Heater, Furnace Oil Heaters, Compressor Air CoolerWaste Heat Recovery BoilersChemical Heat RecoveryFluid heat exchangers, Air Preheaters, Steam Coil Air Preheater, Tubular Air Preheater, Air & Oil Cooled Heat Exchangers, Hydraulic Oil Coolers, Phase-change heat exchangers, Black And Green Liquor Heating, High Pressure Ammonia Chillers, Industrial Refrigerators, Chillers, Evaporator heat exchangers.

Heat Exchanger types based on application

Shell and Tube Heat Exchangers are typically used for high-pressure applications with pressures greater than 30 bar and temperatures greater than 260 °C due to the flexibility of design. Shell and Tube Exchangers can be designed as Fixed tube sheet, Floating head and U tube.


Ammonia as a refrigerant has greatest application in industrial settings, primarily in the petrochemical and pharmaceutical sectors. An absorption refrigerator is a refrigerator that uses a heat source that is waste heat from factories, to provide the energy needed to drive the cooling process.


helps in heating the fuel, improving combustion, reducing the flue gas temperature and increasing the boiler thermal efficiency.


The coolers are often essential for designing temperature-optimized hydraulic systems to keep oil temperatures within a limited range.
