A Shell Tube Heat Exchanger is a class of heat exchanger designs. It is the most common type of heat exchanger in oil refineries and other large chemical processes, and is suited for higher-pressure applications. As its name implies, this type of heat exchanger consists of a shell (a large pressure vessel) with a bundle of tubes inside it. One fluid runs through the tubes, and another fluid flows over the tubes (through the shell) to transfer heat between the two fluids. The set of tubes is called a tube bundle, and may be composed of several types of tubes: plain, longitudinally finned, etc.
There can be many variations on the shell tube design. Typically, the ends of each tube are connected to plenums (sometimes called water boxes) through holes in tubesheets. The tubes may be straight or bent in the shape of a U, called U-tubes.
Shell Tube Heat Exchangers are most commonly used in heating or cooling process fluids and gases. Typically found in applications where a need to heat or cool large volumes exist; however small volume applications are also very common.Shell and tube exchangers come in many variations to meet process requirements in almost every industry or application. They deliver reliable heat transfer performance by utilizing a high turbulence and counter flow, making one or more passes. While one (1), two (2) and four (4) pass models are standard, multi-pass custom models of any size are available.
HRS Process Systems Limited also designs and manufactures ECOFLUX* Smooth Tube Heat Exchanger for various industrial application like heating, cooling, condensing and reboiling in our world class manufacturing facility to cater to Customer’s heat transfer requirement. We manufacture units presently to working pressure of 80 bar for process / service plant and with 0 temperature upto 400 C. For specific design we can manufacture units with 150 bar pressure at 500 C.
Development of Corrugated Tube
ECOFLUX* Corrugated Tube Heat Exchangers (CTHE)use corrugated tubes instead of smooth tubes. The corrugations induce turbulence in the media and ensure high Reynolds number even at low velocity.The development of corrugated tube is perhaps the most exciting advancement in heat transfer technology.
HRS Hot Water System is the most versatile and compact hot water generation system. It provides highly efficient solution to instantaneous hot water generation using energy efficient heat exchangers (Funke Brazed or Gasketed plate heat exchanger or Ecoflux* corrugated tube heat exchanger. HRS Hot Water Systems can also be installed with storage (buffer) vessel for semi-instantaneous applications and in conjunction with solar based hot water systems.
