Plate Heat Exchanger


Plate type heat exchanger one is composed, thin, slightly-separated plates that have very large surface areas & fluid flow passages for heat transfer. plate-heat-exchangers-t-tamilnadu. This stacked-plate arrangement can be more, in a given space, than the shell and tube heat exchanger. Advances in gasket and brazing technology have made the plate-type heat exchanger increasingly practical. The plates produce an extremely large surface area, which allows for the fastest possible transfer. Making each chamber thin ensures that the majority of the volume of the liquid contacts the plate, again aiding exchange. The troughs also create and maintain a turbulent flow in the liquid to maximize heat transfer in the exchanger. Liquid foods such as milk, fruit juices, beers, wines, & liquid eggs are pasteurized using plate-type heat exchangers. Wine and fruit juices are normally deaerated prior to pasteurization in order to remove oxygen and minimize oxidative deterioration of the products. Plate-type heat exchangers consist of a large number of thin, vertical steel plates that are clamped together in a frame.

Specifications of Plate Heat Exchanger:

  • Heat Exchanger behind a heat exchanger is the use of pipes or other containment vessels to heat or cool one fluid by transferring heat between it and another fluid. In most cases, the exchanger consists of a coiled pipe containing one fluid that passes through a chamber containing another fluid.

Applications of Plate Heat Exchanger:

  • No mixing of product
  • Easy maintenance and suitable for CIP, plate pack easily accessible & High heat transfer coefficients
  • Flexibility to change plate arrangement and to add or remove plate Compact constructions Optimized heat recovery

Advantages of Plate Heat Exchanger:

  • Plate Heat Exchanger of the pipe are usually made of metal, or another substance with a high thermal conductivity, to facilitate the interchange, whereas the outer casing of the larger chamber is made of a plastic & coated with thermal insulation, to discourage heat from escaping from the exchanger. The plate heat exchanger (PHE) was invented by Dr Richard Seligman in 1923 and revolutionized methods of indirect heating and cooling of fluids.
