Heat Exchanger Uses in Various Industries

There are many different pieces of equipment that use a heat exchanger to function, and this equipment is used in a wide variety of different industries. In fact, almost everyone comes into contact with something from one of these industries on a daily basis. From food to power, the heat exchanger is a valuable piece of technology that has revolutionised many different devices and industries. Without it, we would not be able to enjoy a number of products or services we have today. Here are a few of these different industries.


A number of different machines are used in the pasteurisation of cream and milk. This process takes milk and heats it to a very high temperature, then holds it at that temperature for a certain amount of time. This kills off a number of different microorganisms that cause food to spoil, spread disease, or cause fermentation when it’s not wanted. A plate heat exchanger is used in these machines to purify the cream and milk. These exchangers may also be used in other devices that purify products to make them safe for consumption.


A heat exchanger can also be found in equipment that is used to help cool beers, soft drinks, and fruit juice. For brewing, a heat exchanger helps to boil and cool down wort, the infusion of grains such as malt before the beer is fermented. It’s also used to cool the final product. In soft drinks, a heat exchanger is used to heat water, pasteurise energy drinks and syrup, and dissolve sugar. This is similar to the exchanger’s use in the processing of fruit juice.


Heat exchangers are used in the creation of ethanol and in processing corn. They are used in the interchange of beer and mash or beer stillage. A heat exchanger plays an important part in cooling mash and cooling the fermented mixture. A plate heat exchanger is particularly useful when the fluid being heated has something solid in it that is weighing it down, which often occurs when making alcohol.

Power Plants

In many types of power plants, various fluids and fuels must be cooled quickly and safely. That’s where a heat exchanger comes into play. It helps cool oil, diesel, and petrol. It can be used to cool rotor blades and bearings as well as steam turbines. Many different types of plate exchangers are used within the power plant and energy sector to keep machines cool and to improve their efficiency.

Marine Industry

Another area that relies on exchangers is the shipping industry. Ships must have the oil in their primary engines cooled regularly to prevent overheating. A heat exchanger is also used to assist with marine HVAC systems and with the production of safe drinking water. While other types of exchangers can be used in the marine industry, plate exchangers are preferred because they’re smaller and more efficient. This makes it easier to fit them into the restricted spaces of marine vessels.
