Advantages of Brazed Plate Heat Exchanger

  • High heat transfer performance due to its unique herringbone plates pattern.
  • Able to operate at higher temperature and pressure due to its tough gasket-less brazed structure which enables tight sealing performance.
  • Compact and light with the use of thinner materials to build.

Brazed Plate Heat Exchanger Working Principle

How Does a Brazed Plate Heat Exchanger Work?

The fluid flow and movement is similar to plate heat exchanger (PHE). However, fluid inside BHE would not have contact with any gasket sealing material. Therefore, lower or higher fluid temperature can be operate inside the BHE. The hot fluid and cold fluid flow in alternate directions through the heat transfer plates.

Product Name
  • Brazed Plate Heat Exchanger
  • Shell and Tube Heat Exchanger
  • High thermal efficiency with overall U value of 4,000 to 8,000 W/m²°C
  • Low Efficiency. Shell and tube heat exchanger having LMTD value from 3°C to 5°C(5°F to 10°F)
  • Lower capital costs, BHE is compact and light and has small footprint.
  • Higher capital costs, shell and tube exchanger is heavier and larger, used more floor space when installed.
  • Fewer materials and parts are used, which resulted in reduction of overall size compared to shell and tube heat exchanger.
  • With same specification, shell and tube exchangers required 4 times the size of a brazed heat exchanger.
  • Maintenance is fairly easy. Can be clean with a quick chemical clean-in-place method.
  • Cleaning and maintenance are much more complicated. Tubes are intertwined inside the shell.

Brazed Plate Heat Exchanger Applications

Refrigeration Air Conditioning


The BHE is employed for various kinds of heat exchangers such as the evaporator, condenser, oil cooler, and subcooler in compression refrigeration cycles. The compact BHE uses the least amount of coolant necessary even while improving device performance. It is used in various air conditioners. 


The BHE is also used in absorption refrigerators used in large scale air conditioning. Use the highly efficient BHE in solution heat exchange or drain heat exchange to help improve device performance. 

Refrigeration Cycle (Flow)

There are two types of refrigeration cycles: “compression” through an electric compressor, and “absorption”, heat-driven by steam or burning gas. Recently, energy efficient “heat pumps” have been used to prevent global warming. This “heat pump cycle” has the same principle as the “refrigeration cycle”. Many brazed plate heat exchangers are used for their efficiency even in heat pump cycles. 

Hot Water Heating System

Heat Pump

Heat pumps are gaining attention as a re-usable energy source. By using a BHE, which can handle high pressure, as a condenser, they can efficiently provide hot water. 

Hot water heater

The BHE is optimal for raising the temperature of cold water in a system that provides hot water separately to each household through heat exchange between tap water and a centrally produced heat source.


The BHE matches non-pressure open-type boilers that require heat exchange with the boiler water, and is used by many manufacturers.


The BHE is used for various uses, such as heat collection and heat release. In the bare minimum amount of space necessary, it can increase the heat recovery rate and improve device performance, and is absolutely necessary for compact cogeneration systems.

Industrial Instrument Temperature Control

This is used in many devices such as temperature control systems for hydraulic fluid, lubricant, and finishing liquid necessary for various machining tools and presses, and cleaning agent temperature control systems for various kinds of washers. The BHE is also used in temperature control inside semiconductor manufacturing equipment, which requires precise temperature control and reliability.
