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 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 [...]

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?

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
21 May

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 [...]

Preheating resistor

The advantages of using preheating resistors

It is essential that a generator set, operating in emergency, takes the load quickly and reliably, when there is a power failure, at the main source. For this to occur, the preheating resistance is essential, because it keeps the antifreeze warm and makes it circulate through the engine block, ensuring that it is always at a controlled temperature and ready to start at any time. The heating of the engine of a generator that is inside a building with controlled temperature [...]
