Plastic Fuel Tank

The advantages of the plastic fuel tank

At Grupel, we are 100% dedicated to innovation and to the constant improvement of all the elements that make up and contribute to the good functioning of our generators. We believe that the quality of each piece makes a difference in our final product, making it increasingly more competent and reliable. That is why, with the last update of our standard generators, fuel tanks are now made of plastic. Currently, our equipment has this type of deposit, entirely in plastic [...]

Grupel Solutions for Agriculture

Grupel solutions for the agricultural sector

Over the years, Grupel has been creating and developing quality solutions for the agricultural sector, with equipment that is capable of truly supporting producers and their needs at every stage. This sector depends on energy in all its phases, from planting to harvesting, through the feeding and treatment of livestock. Given the conditions it presents today and being an area that is increasingly automated and dependent on machinery, it cannot suffer power failures or from being energized by an unstable [...]

In addition to specific attributes and powers (between 2 and 6.9kW), the three models in [...]

Resistência Anti Condensação

The role of the alternator’s space heater

The space heater’s purpose is to reduce the moisture in the alternator. The integrity of the insulation and the components of the generator, namely of the alternator, must be carefully preserved, and one of the easiest and most effective ways to prevent the accumulation of moisture and condensation is the use of space heaters, as these utensils maintain an adequate temperature so that the conditions for condensation are not met.These components are recommended for:places where the relative humidity is high places [...]

What are the PMG and AREP for?

What are the PMG and AREP Systems for?

To ensure the generator’s stable operation, it is important that there are no major voltage fluctuations. For this purpose, an excitation current is created to provide power to the AVR (Automatic Voltage Regulator), a device that maintains the generator's nominal voltage at a preset value, even when there are sudden load variations or in the case of special operations, such as:parallel operation between generators parallel operation between the generator and the grid start-up of more demanding equipmentIn regular [...]

Backup / standy generator

How does a standby / backup generator work?

Power failures are inevitable, whether due to technical issues or adverse terrain and weather conditions. Standby generators or emergency run generators are used to, in situations like these, fill in as the main source of energy in the event of a network failure. Having an alternative source of electricity is a useful and often highly necessary option, with many sectors and activities relying on energy continuously. Places such as supermarkets, hospitals, clinics, data centers, industries, works, events, among others, cannot [...]

Grupel solutions for telecommunications

The telecommunications sector is made up of huge transmission equipment, such as towers, antennas, and a large technological infrastructure, whose energy consumption is remarkably high. Therefore, this market has very demanding needs. The generators that operate to assist this sector must be adapted to difficult conditions, often having to operate in a continuous regime (24/7), for years. The costs are very high, if you take into account operation, maintenance and fuel. Reliability is an important factor in ensuring the success of [...]


What is the fuel pre-filter for?

To ensure the proper functioning of your generator, it is essential that its components operate properly. There are some elements that help to maintain the state of conservation of the circuits of the group and of its components and, thus, ensure their correct functioning. The pre-filter, for example, has the purpose of separating water from fuel and removing residues in it, preventing them from being pumped into the engine and causing oxidation, corrosion and cavitation problems in the cylinders. It is [...]

What is an inverter generator?

What is an inverter generator?

Two weeks ago, we presented our new range of portable generators Grupel, consisting of three equipments, including an inverter generator. All have specific powers, characteristics and attributes, adapted to different requirements and requirements.But what does really differentiate an inverter generator? Basically, the major distinguishing factor is the energy generation process, which includes more steps. That is, an inverter generator produces direct current energy and converts it into alternating current energy, which improves the quality of the power, since alternating current wastes [...]

electronic speed control

What does the electronic speed control of the engine do?

The electronic speed control is an element that optimizes the work of the generator and makes it more competent, because it automatically manages the engine speed when there are more demanding loads. Diesel engines, especially those with lower power, are generally mechanically regulated, which means the engine speed adjustment is done mechanically. However, when working with more demanding loads, electronic control is the best solution, since the speed adjustment is done electrically, and this considerably reduces the engine's response time [...]
