Heat Exchanger

What are heat exchangers shell and tube?

Shell and tube heat exchangers consist of a series of tubes which are fitted in the shell ends, just like the Kenics Unit, the Kenics Units have the addition of mixing elements in the tubes to ensure that higher viscosity liquids are continually turned into the tubes so that it is not just the liquid in contact with the tube walls that is heated or cooled.

Shell and tube heat exchangers are typically used for high-pressure applications as they are robust due to their shape.

What are u tube heat exchangers?

A standard Shell and Tube heat exchanger has straight tubes going to each end of the unit, whereas, a U Tube Unit has the tubes going to only one end of the unit. In other words, the tubes inside the unit are bent into a U and go back to the same end.

Which type of heat exchanger is more efficient? Advantages and disadvantages?

It depends on the application. The Plate type Heat Exchanger is more thermally efficient and cheaper because the sheets are just be stamped out with the channels indented into the Plate and are used in the Dairy Industry for Heating or Cooling Milk, they are only suitable for light liquids and the Plate type Heat Exchanger have a limitation on the pressure rating up to 30 bar.

How do you size a heat exchanger?

You calculate the heat or cooling capacity required to get the required output, the client will inform you of the process temperature and the required temperature to be achieved.

In Kelvion, we use in house selection software to size Plate type heat exchangers.

Which type and brands of heat exchangers does Flexachem supply?
