The main function of the industrial generator is to maintain the electricity supply during blackouts. The presence of this equipment in companies is essential so that productivity is not impaired, in addition to promoting greater safety to the environment.

But with a multitude of models of this equipment available on the market, deciding on the best type requires a lot of attention.

There are several other more specific questions that will help you a lot when it comes to purchasing the right equipment for your business. After all, the generator used in an industry cannot be the same for small businesses, right?

In today's post, we will talk about the main characteristics of the most used generators on the market, diesel and gasoline. Understand what are the advantages and disadvantages in the use of each equipment and for what types of business they best apply.

What is the difference between the diesel and gasoline power generator?

The type of fuel is a very relevant factor in the choice of the energy generator.

Despite performing the same function, diesel and gasoline generators are indicated for specific situations according to the individual characteristics of each model.

Now let's look at the advantages and disadvantages of these generators.

Diesel generator


They have power capacity above average compared to other models;
Cheaper fuel and maintenance value;
Longer service life depending on conditions of use and installation;


They are noisier;
Higher rate of emission of gases harmful to the environment;
The technical assistance for this equipment requires extra attention due to its structure being more complex;
If installed in a low temperature location, the equipment takes longer to produce energy at its nominal power;
High acquisition cost;

Gasoline generator


They are quieter;
Easy to transport;
Lower pollution level compared to diesel fuel;
Low acquisition cost.


More expensive fuel and maintenance cost;
They require a greater amount of fuel to operate;
Limited power capacity compared to diesel-powered;

After all, what is the best model to invest in?

In short, both are quite efficient. The choice will depend on the purpose for which the equipment will be applied.

In cases of sporadic use, gasoline is more suitable. This model can be applied in small and medium-sized establishments (schools, shops), farms and homes.

Industrial diesel generators are preferentially used to supply electricity in more complex work environments and require continuous electricity, such as construction sites, hospitals, airports and industries.

Therefore, if you are looking for an alternative energy source to be applied only in blackout situations and which have a simpler configuration, the gasoline engine can completely supply the electrical network of the space where it is inserted.

But, if the intention is to have all the electrical part constantly active regardless of the local network, especially in larger spaces, invest in the diesel generator.

Another important factor when deciding on the ideal generator model, it is essential to make its dimensioning correct.

In this way, you will be able to identify the appropriate power level to be able to supply the required energy capacity of the environment where it is installed.

How does the diesel generator work?

Usually, it is the model chosen for large installations, as it has more robust capacity. It caters for frequent and intense uses and manages to generate 800 to 125,000 watts.

It is produced in portable (open) and cabined versions, with digital panels, cooling systems (air or water). The relevant technical specifications for a diesel generator are.

Engine type - whether it is 2 or 4 stroke, which directly affects the power of the machine.
Tank capacity - information needed for you to make consumption calculations, for example, and detail averages.
Maximum power - expresses the equipment's capacity.
Number of phases / voltage - whether it is single-phase or three-phase.
Battery charger - it is common for generators to have a battery, but at the time of purchase it is worth checking out this detail.
Noise emission - technical data that is expressed in decibels, an important measure, especially if people are going to be exposed to the machine during its operation.

It is certain that these characteristics are present in the diesel or gasoline generator. On the other hand, cab models are equipped with automatic voltage regulators, which prevent short circuits, for example.

How does the gasoline generator work?

It is a very versatile device, as it can be used in camping spaces or in small construction sites. Normally, it is triggered when the distribution of the public power grid is interrupted.

Its main presentation is the portable models, which are connected manually retractable or by electric starter. Other technical features:

The engines are 2 and 4 stroke;
They are bivolts (110/230 V), guaranteeing their use in all Brazilian regions;
They also operate on single-phase and three-phase voltages;
Tanks with capacities from 3.5 to 25 liters.
The maximum power of this type of equipment varies from 2.2 to 9 kw | kva. The tip is to check how much you will need to connect your equipment, whether in a residence or commercial establishment.
