Shell and Tube Heat Exchanger
A shell and tube heat exchanger is a type of heat exchanger that consists of a shell (a large pressure vessel) with a bundle of tubes inside it. These tubes are typically arranged in a way that allows fluid to flow through them while another fluid flows over the outside of the tubes. Heat is transferred between the two fluids through the tube walls.
Here’s how a shell and tube heat exchanger typically works:
Shell: The shell is a large cylindrical vessel that contains one of the fluids. It is usually made of metal and is designed to withstand high pressure.
Tubes: Inside the shell, there is a bundle of tubes through which the other fluid flows. These tubes can be straight or bent and are typically made of metal such as copper, stainless steel, or titanium. The tubes are sealed at both ends to prevent leakage.
Tube side and Shell side: The fluid flowing inside the tubes is referred to as the tube side fluid, while the fluid flowing outside the tubes, within the shell, is called the shell side fluid.
Heat Transfer: Heat is transferred between the tube side and shell side fluids through the tube walls. The temperature difference between the two fluids drives the heat transfer process. For example, if the tube side fluid is hotter than the shell side fluid, heat will transfer from the tube side fluid to the shell side fluid.
Baffles: Baffles are often placed inside the shell to direct the flow of the shell side fluid. These help improve heat transfer efficiency by promoting turbulent flow and preventing the formation of stagnant zones.
Tube Layout: The tubes can be arranged in various configurations, such as parallel, triangular, or square patterns, depending on the specific application and heat transfer requirements.
Fluid Connections: Inlet and outlet ports are provided for both the tube side and shell side fluids to enter and exit the heat exchanger.
Shell and tube heat exchangers are commonly used in various industrial processes, including power generation, chemical processing, refrigeration, and HVAC systems, due to their versatility, efficiency, and ability to handle high pressures and temperatures. They can be designed and customized to meet specific heat transfer requirements for different applications.
Types
A DX (Direct Expansion) chiller, also known as a DX refrigeration system or DX cooling system, is a type of air conditioning or refrigeration system commonly used for cooling buildings or industrial processes. In a DX chiller, the refrigerant directly cools the air or process fluid without the use of an intermediate heat exchanger.

A flooded shell and tube heat exchanger is a specific type of heat exchanger design primarily used in industrial applications where precise temperature control and high heat transfer rates are required. In this design, the shell side of the heat exchanger is flooded with the fluid being cooled or heated.
Capacity :
30 - 1000TR(Single Circuit)
An oil cooler is a type of heat exchanger specifically designed to cool oil or other fluids by transferring heat away from them. Oil coolers are commonly used in automotive, industrial, marine, and aerospace applications to maintain optimal operating temperatures and prevent overheating of the lubricating oil or hydraulic fluid.

200-300TR (Double Circuit)
A U-bundle shell and tube heat exchanger is a specific type of shell and tube heat exchanger configuration characterized by the shape of its tube bundle. In a U-bundle design, the tubes are bent into a U-shape, hence the name, and arranged within the shell of the heat exchanger.
