Choosing the right generator for your needs can be a difficult task. Everyone wants to have a reliable and efficient generator that doesn’t require much attention. Power generation is an essential part of any worksite, so in an ideal situation, one shouldn’t have to worry or lose sleep over the functionality of a generator.  

Nowadays there are many different generators available for purchase. This article examines specifically two types of generators found in the market: diesel generators and hydraulic generators. Both possess unique characteristics that make them suitable for various applications, but understanding their differences and weighing their advantages is crucial in making an informed decision. 

Size and movability 

One of the appealing differences can be seen immediately when looking at these two products side by side: the size difference is remarkable. Diesel generators are considerably bigger in size than hydraulic generators, which makes hydraulic generator easier in mobile and logistical use: it’s always onboard within a vehicle or a machine and therefore, never in the way of action. Our Super Compact HG Hydraulic Generators can be up to 95 % smaller than diesel generators with equivalent power. This saves time since there’s no need for additional trailers for transportation. On the other hand, if you wish to leave generator to the worksite, you may consider diesel generator.  

Emissions 

Nowadays, emissions have to be taken into account. Diesel generators are not extremely environmentally friendly to begin with: they emit pollutants such as nitrogen oxides, particulate matter, and carbon monoxide when in use. There are some reducing factors, though; diesel generators can generate more electricity per unit of fuel consumed compared to some other generator types due to their fuel efficiency.  

In case of hydraulic generators, the emission levels depend on the machine’s or vehicle’s engine that provides the hydraulic power for the generator. But broadly speaking, machinery and vehicles often have stricter emission standards than small combustion engines, which are used to run diesel generators. So, by choosing a new vehicle or machine that has low emissions, you may also run the generator with low emissions.   

In both cases, you can also impact the emissions of a generator by choosing more environmentally friendly fuel options like, for example, biodiesel or even hydrogen. 

Maintenance 

Diesel and hydraulic generators are tough fellows and designed for professional usage. But, when it comes to their maintenance, there are big differences. Both of these generators, of course, benefit if they are cleaned properly once in a while. But overall, a hydraulic generator requires much less attention from the user than diesel generator, and here is why. 

For instance, a diesel generator has an engine, which means one engine more to maintain. For example, the diesel generator’s fuel filter must be changed on average every 500 hours. A hydraulic generator utilizes a machine’s or vehicle’s engine, so it doesn’t bring anything new to your maintenance schedule. The hydraulic generator itself is robust and built to last. It needs no regular maintenance.  

Hydraulic generator users have also mentioned that they like that with hydraulic generators you don’t have to hassle with diesel or gasoline. As a hydraulic generator uses a machine’s engine, it also uses its fuel system. As a machine’s or vehicle’s fuel tank is much bigger than diesel generators, you don’t need to refuel it so often. Also, space is saved from your machine or vehicle because, in many cases, you don’t need to have spare fuel canisters with you.  

Maintenance could be a deciding factor when comparing these two generators. This category is heavily divided: hydraulic generators are low in maintenance, whereas diesel generators require regular maintenance such as oil changes and general inspection. 

In conclusion 

Hydraulic generators are used in environments where hydraulic power is available, such as in mobile use and construction sites. It is important to notice that any vehicle can produce hydraulic power with hydraulic power take-off. And if you are not familiar with the concept, you may read more about hydraulic power take-offs by clicking this. Diesel generators are used in versatile worksites and even for home use. To determine which of them is the best option for you, it’s necessary to think about your own needs. This list showcases each generator’s special characteristics and traits, and you might want to compare their pros and cons before deciding between them.
