Plate Heat Exchanger (PHE)

The plate heat exchanger is a type of heat exchanger that can be installed in the process line or utility line to heat or cool a fluid. It uses a very thin sheet of corrosion-resistant metal (such as stainless steel, or titanium) to transfer heat between two fluids. Compared to a conventional heat exchanger, a plate heat exchanger has a larger surface area, thus the heat transfer rate is increased.

Plate Heat Exchanger Working Principle

How Does a Plate Heat Exchanger Work?

The plate heat exchanger is used to transfer thermal energy between two fluids without allowing the fluids to mix together. Multiple plates are stacked together and gaskets installed on the plate to prevent the fluids from entering alternating plates. Thus, fluids flow into the channel counter-currently in the heat exchanger to achieve optimal heat transfer.

Principles of Heat Exchange

Heat exchange is the transfer of heat energy from a high-temperature fluid to a low-temperature fluid. Heat energy has the property of moving from high to low.

As a method of heat exchange, a bulkhead method in which two types of fluids are made to flow through a solid wall separated by metal etc. and transmit the energy of each other. This method is easy to handle both fluids and versatile to operate with different types of fluid. By using this method, high-temperature and low-temperature fluids are made to flow alternately, and thermal energy is transferred to lower the temperature of the high-temperature fluid.

Bulkhead type heat exchangers are used in a wide range of industrial fields, such as the heating, cooling, concentration, vaporization, condensation and heat recovery of fluids. In contrast to the bulkhead method, a direct contact method is also used in which fluids such as air and water are brought into direct contact and the temperature of each other is transmitted. This method is frequently used in cooling towers that promote evaporation of water with air and cool warm water, and barometric condensers that directly cool gases such as steam and warm air with cold water.

Everyday Applications


Air conditioners

Air temperature in the room is conditioned by cooling and warming the air by the indoor unit. Heat exchangers are installed in both the indoor unit and the outdoor unit respectively. So, one air conditioner system is made up of two heat exchangers.




Water that used to cool the engines of cars or motorcycles is cooled with air.



Water Heaters

Hot water that is used at home is heated with a heat exchanger.



Heated Pools, Hot Springs, Aquariums

Heat exchangers are used to heat the water in pools, cold springs, and to control the water temperature in aquariums.


Plate Heat Exchanger



It has a high heat transfer performance by using a thin plate with a corrugated pattern for the heat transfer section, and it is used in a wide range of applications because it is lightweight and compact.


  • High heat transfer coefficient: The overall heat transfer coefficient is much larger than that of the multi-tube type, because a turbulent flow effect can be obtained.
  • Self-cleaning effect: The turbulent flow effect makes it difficult for dirt to adhere to the surface of plates.
  • Compact: The footprint is small due to the high heat transfer coefficient and the maintenance space within the frame itself.
  • High heat exchange efficiency: Since heat exchange can be performed in a complete counter flow, it is possible to approach a difference of 1°C between the inlet temperature on the high temperature side and the outlet temperature on the low temperature side.
  • Increase/decrease heat transfer area: Since the heat transfer plates are arranged in vertical-stack structure, it is possible to change the heat transfer area by increasing or decreasing the number of heat transfer plates. (However, it depends on the dimensions of the frame.)



We create our heat transfer plates by pressing thin sheets of corrosion-resistant metal such as stainless steel or titanium using specific mold and apply gaskets as a sealing method. Several heat transfer plates are stacked between the fixed and moving frames, which have a guide bar for suspending the plates, and then tightened with tightening bolts. Gaps between the heat transfer plates allow the fluid to flow. High-temperature fluid and low-temperature fluid flow through every other plate, usually forming a countercurrent flow. Many types have specialized functionality, depending on the plate press shape and structure.

Product Name
  • Plate Heat Exchanger
  • Shell and Tube Heat Exchanger
  • Plate heat exchanger is able to achieve a very low LMTD of 1°C(2°F)
  • Low Efficiency. Shell and tube heat exchanger having LMTD value from 3°C to 5°C (5°F to 10°F)
  • Lower capital cost, plate heat exchanger is lighter compare to shell and tube exchanger and uses less floor space when installed.
  • Higher capital costs, shell and tube exchanger is heavier and larger, use more floor space when installed.
  • Plate heat exchanger is flexible and easy to adjust capacity to meet changing requirements, by simply adding or removing the plates while maintaining the existing frame.
  • Shell and tube exchanger is not flexible to adjust the capacity, as its capacity is fixed and decided when installation.
  • Maintenance is fairly easy, just by simply removing the tightening bolts and nuts.
  • Cleaning and maintenance are much more complicated. Tubes are intertwined inside the shell.
