Heat Exchangers

EEI has designed, manufactured and supplied heat exchangers heat duty ranging from 2500 kcal/hr to 37,40,500 kcal/hr.

Heat exchangers are devices used to transfer heat energy from one fluid to another. The fluids are separated by a solid wall to prevent mixing.

We have manufactured Heat exchangers for various applications including space heating, refrigeration, power plants, chemical plants, petrochemical plants, petroleum refineries natural gas processing and sewage treatment Heat Exchangers are manufactured as per ASME, HEI and TEMA code of practice.

Application of Heat Exchangers

Various Shell And Tube Heat Exchangers for Turbine Oil Cooling, Boiler Feed Water Heating application, Compressor Air Cooling, DG Set Engine Water Cooling Chemical Heat Recovery, Waste Heat Recovery, Fluid heat exchangers, Phase-change heat exchangers and Black And Green Liquor Heating

Various types Based on Application

…..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


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.
