Generator Hire: Air-Cooled vs Liquid-Cooled

Our thoughts in this post turn to air cooled vs liquid-cooled generators, and to our customers and new visitors to our site, who might appreciate an explanation as to what they are and what the differences might be. We like our customers to make educated decisions about which generator hire is right for their needs, and we do this by providing a range of informative posts that talk about the most pressing concerns and queries they might have. Today it’s the turn of our air-cooled vs liquid-cooled generators.

Overheated generators are damaged generators.

As you can imagine power generators can produce an intense amount of heat making the insides so hot they could be irreparably damaged. However, what keeps the components cool are the air-cool and liquid-cool systems. What do they do and which generators will have them?

In the main, whether it’s air or liquid will largely depend on the generator’s size and type. Normally an air cooling system will be installed in a smaller generator while a larger one will have a liquid cooling system. These differences are there to deliver the right amount of power safely.

Now we know which type of cooling system serves which generators, the next question we need to ask is ‘what are the advantages and disadvantages of air or liquid cooling systems?’

Air cool system generators.

Air circulation is what smaller generators use to keep them working efficiently, keeping the insides from heating up. Cooler air is taken in and then distributed within the generator to keep the parts cool and safe from burning. An air cooling system is normally used in smaller generators such as portable or standby generators. There are two options and these are completely enclosed systems or open ventilated systems. 

The ones using open ventilated systems take in air and then release it back as exhaust. Air-cooled generators have some limitations however, they can overheat if used for a long period of time. When they fail as a result of this, the repairs can be extensive, which is something you need to be aware of. As you can imagine then, air-cooled engines need good maintenance to keep them in tip-top condition.

Liquid cooler generator systems.

A generator of this type, using liquid cooling systems will use different types of fluid to keep it in good working order. These are oil or other types of coolant. They are a little more expensive to buy because they are far more efficient than air cooling systems. 

As well as the coolant liquids we’ve mentioned, a liquid cooling generator system will also rely on a water pump and radiator. The pump distributes the liquid through the generator where the air will cool it. A lot of complex design goes into making liquid-cooling systems and they are by and large much more powerful and last much longer than air-cooling systems. Liquid generators are usually in use within industrial commercial organisations because there’s much more demand for power than smaller domestic properties.

The next question then is, which system do you need?

Well, that largely depends on what you’re going to be using it for. Air cooling systems are better for smaller domestic properties with less demand, while liquid cooling systems are better suited for bigger areas with more complex needs.
