Industrial Heat Exchangers: How They Work and Why They Are Necessary

Industrial Heat Exchanger

At industrial facilities and worksites, heat exchangers are one of the most versatile, durable, and necessary pieces of equipment, and their usefulness isn’t just limited to one industry. The impact of heat exchangers is widespread, as they used for everything from oil refining, to processing food and dairy products, to brewing beer, to propelling large ships across the sea.

Although heat exchangers are used for residential purposes, as well, for our purposes we are going to focus on how they work and why they are so indispensable in an industrial setting. To start with, what, exactly, is an industrial heat exchanger and how does it work?

Best Industrial Heat Exchangers for Small Floor Spaces

Industrial Heat Exchangers

Many industrial applications require a heat exchanger, but, when space is scarce, is it even possible to find one that’s small enough to fit? Even if you can find a compact heat exchanger that works for your space, is it even capable of doing the job you need it to do?

When people think of heat exchangers, the one thing that comes to mind is an old shell and tube heat exchanger. Great machines, but hardly plausible if you’re dealing with tight quarters. Fortunately, there are industrial heat exchangers available that not only fit in tight floor spaces, but which do the job of a machine many times larger. These compact heat exchangers are revolutionizing the way people think of heat exchangers and what they’re capable of, regardless of the size of the space available.

5 Money-Saving Maintenance Tips for Heat Exchangers

Heat exchangers are used in so many ways, it’s almost impossible to keep track of them all, but one thing they have in common is that they all need regular maintenance to operate at an optimum level. If proper maintenance isn’t performed, dirt and sediment will build up, parts will break down, and performance will suffer.

Ultimately, these problems all lead to downtime and can cost you a significant amount of time and money. With that in mind, we will discuss some heat exchanger maintenance tips that can save you both time and money now and into the future.

Everything from home heating and cooling systems to rocket ships depends heavily on a heat exchanger’s ability to normalize the temperatures of liquids and gases used in their systems.

This level of versatility is why heat exchangers are one of the most sought-after devices on planet Earth and also begs the question – should you consider getting a heat exchanger? And, if you already have one, when is it time to replace it?

With these questions in mind, we’re going to discuss when to get or replace a heat exchanger, the difference among the different types, which heat exchanger is best for your application, and which type of company to buy from.

Workplace Safety Tips for Operating Heat Exchangers

Plate, shell and tube, and air cooled heat exchangers combine to function for a variety of applications and are prevalent in a number of industries. If you work in an industry that uses machinery of any type, you probably knowingly or unknowingly work alongside a heat exchanger on a daily basis. While heat exchangers are incredibly useful and relatively safe to operate, there are precautions to should be taken when starting, running, and shutting them down.

Here are a few tips that can help keep you safe when operating a heat exchanger at work.

When Does a Heat Exchanger Need to Be Repaired?

It’s not always obvious when a heat exchanger is going to stop working, which makes it difficult to know when it needs to be repaired. Complicating matters even further is deciding whether you should have your heat exchanger repaired or have it replaced altogether. Fortunately, there are ways to tell which option is best so you’re able to get your heat exchanger up and running again as soon as possible.

What Engineers Need to Know About Plate Heat Exchangers

Many plant processes require heat exchangers to transfer energy from one fluid or gas to another without mixing them together. Being essential parts of both comfort and process heating and cooling applications, heat exchangers perform efficiently for a long time without much thought.

Plate heat exchangers are one of the most popular types due to their efficiency and versatility. Made up of two metal end plates that envelop many thin metal plates located in close proximity, a liquid is pumped into one side of the plates and another liquid is pumped into the other side. As both liquids contact as much surface area as possible, heat is exchanged from one liquid to the other liquid.

Differences Between Plate Heat Exchangers and Other Heat Exchangers


Flat plate heat exchangers, also known as plate and frame heat exchangers, transfer heat between two fluids using metal exchanger plates. These heat exchangers are made of plates sitting alongside each other that have four opening ports. The plates on these units have a gasket fitted between them that creates space so fluid can flow between two ports and change direction when necessary.
