We have large experience in thermal design of heat exchangers and are capable to design an exchanger in most optimum manner. We have designed some shell-and-tube exchanger under very stringent Process conditions such as viscosity of Process fluid as high as 17000 cP and approach as low as 3 degree Celsius.  Such a low approach is generally not conducive for shell-and-tube type exchanger. Yet, as per the client’s requirement, we designed the shell-and-tube exchanger with lowest possible heat transfer area.

The optimum design of an exchanger involves:

Selecting TEMA type of the exchanger
Finding optimum surface area for a given duty and within the pressure drop limitations
Maximizing EMTD (effective mean temperature difference) and heat transfer coefficient for given pressure drops
Optimizing number of tube passes
Managing the pressure drops
Fixing the tubesheet layout
Defining the nozzle sizes
Analyzing flow induced vibrations, etc

We have capability to design following type of heat exchangers:
i) Shell-and-tube heat exchanger
ii) Double pipe exchanger
iii) Water bath heater or line heater
iv) Plate and frame exchanger
v) Air-cooled exchanger
